Treatment and destruction of bedbugs with hot and cold fog - reviews and tips

What is hot fog

This is the name of the method of treating a room.
In this case, the output is a gaseous substance, which is mixed with the insecticide. As a result, the poison enters the air and spreads throughout the room, due to its high volatility. Preheating accelerates the process of releasing the toxic substance. A smoke bomb operates on a similar principle. However, in this case the substance spreads naturally. When hot fog from bedbugs is used, the gas is supplied under pressure. At the same time, a high rate of filling the air space of the room is noted. Heating technology is used to quickly deliver the toxic substance into the air, but additionally, when the temperature changes, the hot steam condenses. This leads to the appearance of small droplets of the toxic substance.

They settle on the surface

very slowly, which is due to the minimum weight of the particles (their size is 20 microns).

The dissolved insecticide is supplied under pressure and heated

Comparison of cold and hot fog

The mechanism for obtaining a cloud from a toxic substance is similar in both cases. So, if a cold fog is considered, then the poison does not heat up, as can be guessed from the name. But the substance is also supplied under pressure using a fog generator. Such devices are designed much simpler, which makes it possible to use some of the models at home.

Thus, a cold fog generator works on the principle of spraying a working solution. The liquid from the chamber is supplied to the nozzle, and a vapor cloud at room temperature is obtained at the exit. Heating is not provided in this case. The methods (cold and hot fog) differ in a number of features:

• the range of models of devices for spraying hot fog does not include devices that could be used at home;
• the technique of spraying a hot insecticide provides a better result than that which requires the need to perform treatment with a cold substance, and the heated insecticide destroys even parasite eggs;
• cold mist can be sprayed independently, but the level of processing efficiency is not high, since you need to know the nuances of the procedure.

Hot fog generator

A special technique is used to spray the insecticide. It is used during professional processing. Such devices are expensive, so they are not used in domestic conditions. In addition, they are quite complex and require care and skill during operation. So, inside the mechanism, hot gas, supplied under pressure, and a toxic substance are mixed.

At first it helps

transition of the insecticide into an aerosol state, and under the influence of high temperature the poison evaporates, which leads to the appearance of hot steam.

The difference in the method of spraying substances of different temperatures is also due to the fact that when using cold fog, the size of the particles that are released from the nozzle is always the same. In the case of hot steam, a change in the size of microscopic droplets of fine suspension is observed.

The value of this parameter depends on the environmental conditions. If the humidity level and air temperature change, there is an increase or decrease in particles. Exterior view of one of the hot fog generators

Hot fog

Killing bedbugs with hot fog makes it possible to get rid of pests in one treatment. Repeated manipulation is performed only if the bedbug population is excessively large, as well as in a residential area that has all the conditions for the reproduction of blood-sucking insects.

What is hot fog

Destruction of bedbugs with hot fog is a professional treatment of a room using a hot steam generator. The device is filled with a working solution consisting of several insecticides. It is heated above 50°C and sprayed indoors.

Heating occurs in a few milliseconds, after which a gas stream is supplied from the nozzle of the unit under pressure.

During contact with relatively cold air in the room, the gas cools and moisture condenses in the form of droplets from 1 to 20 micrometers. They create a dense cloud and travel far due to the speed of the gas supplied from the nozzle.

How it works and how to treat it

Treatment with hot fog against bedbugs creates a kind of cloud in the treated room, consisting of fine particles of insecticide, which remain suspended for a long time (3-8 hours). They easily penetrate into the most inaccessible crevices and microcracks.

At temperatures above +50 °C, mature bedbugs and their eggs die instantly. As it cools, the insecticide settles on the surface, forming a thin film. When surviving parasites come into contact with it, they receive a dose of a destructive insecticide, which inevitably leads to their death.

All horizontal and vertical surfaces and interior items are covered with a toxic film. The chances of survival for blood-sucking insects are reduced to zero.

Treating an apartment against bedbugs with hot fog has the following advantages::

• processing takes minimal time;
• an insecticide heated to high temperatures penetrates deeply into the most hidden places, therefore causing the death of both bedbugs and other crawling parasites;
• after treatment there are no sharp, persistent odors in the room;
• The hot cloud not only gets rid of blood-sucking parasites, but also eliminates mold, fungi and other pathogenic microorganisms.

This method of pest control has virtually no disadvantages . Although it is not suitable for some rooms due to high humidity. It is also impossible to practice it at home on your own and you need to call specialists from insecticidal services.

How does hot fog affect bedbugs?

A fine aerosol fills the space in a matter of minutes. The room temperature rises to 45-50°C. The effect of the poison in a “foggy” state is enhanced several times. Due to their microscopic size, the chemical particles continue to hover in the apartment for up to 8 hours.

Along with the air, the heated insecticide penetrates into the farthest corners of the home: between sofa cushions, behind furniture, under wallpaper and in cracks. Under the influence of high temperatures, some pests die instantly - heating to +45°C is destructive for bedbugs and eggs.

During the cooling process, the poisonous cloud settles, covering the floor, furniture and other objects with an invisible film. Surviving insects receive a dose of poison and die over time. Flies, ants, and cockroaches have no chance of salvation.

How long do bedbugs live after fogging?

Adult individuals, one way or another, during the volatility of the clouds come into contact with the poison and die after a quarter of an hour. Hot toxic fog enters through the protective shell of the eggs and completely destroys them within 5-6 hours.

The duration of action and effectiveness of disinfestation is largely determined by the composition of the poison against bedbugs. Only a specialist can choose the reagent correctly. A professional takes into account many factors:

• Effectiveness of components;
• Harm to humans from use;
• Intensity and persistence of odor;
• Preparations and methods previously used to kill bedbugs in the house.

Bed bloodsuckers quickly adapt to poor conditions. If the previous removal of bedbugs did not give the desired result, then the surviving individuals have developed resistance to certain chemicals. This information must be provided to employees of the Sanitary and Epidemiological Station or representatives of a private disinfection service.

Treating a room against bedbugs with hot fog

Before treating an apartment with hot fog, it is necessary to select a pesticide with which to spray the home. It is necessary to take into account whether disinfestation was carried out in this room previously, and what insecticide was used. Insects can develop immunity to the drug.

Corpses

What solution is used to treat bedbugs?

The choice of preparations for hot fog treatment against bedbugs is quite wide. They are divided into:

• contact;
• intestinal;
• contact-intestinal.

Use liquid products or soluble powders. To increase efficiency, a solution is prepared from a mixture of different types of substances. When treating an apartment with hot steam against bedbugs with the help of hired specialists, it is better to leave the decision on choosing a product up to them. When purchasing on your own, preference should be given to the latest products to which the parasites have not yet developed immunity.

How long does it take for bedbugs to die after treatment?

The effectiveness of killing bedbugs with hot fog depends on several factors. Death may occur:

• Instantly. When an individual gets exposed to a large dose of insecticide. This is achieved by directing the generator nozzle directly into the socket.
• Within 6–8 hours. A suspension of a toxic substance settles on the parasites and causes damage to the nervous system.
• For 10 days. The dose of the chemical was too small to quickly kill the insect.

In case of severe infection, the possibility of survival of several individuals cannot be ruled out, for which a low dose of insecticide serves as a kind of vaccination against the active poison. A specialized organization usually gives a guarantee for its work and, if the bedbugs survive, will carry out re-treatment. This will require another drug.

Preparatory activities

Treatment with cold and hot fog against bedbugs requires scrupulous preparation of the room, so you should reserve time.

Before poisoning, it is necessary to perform a set of measures:

1. Take children and animals out of the apartment so that they cannot inhale the fog. Temporarily you will have to move aquarium fish to another place - rising temperatures are detrimental to aquatic pets.
2. Indoor flowers can be taken out to the balcony if disinfestation is carried out during the warm period of the year.
3. Place food in the refrigerator or take it out of the apartment.
4. It is advisable to cover household appliances with polyethylene.
5. Carry out a small redevelopment: move large furniture away from the walls, remove bed linen from the bed, raise mattresses, lay out pillows.
6. It is advisable to pack clothes, curtains and other textiles in bags and place them in a closet.
7. Wash bedding at +60°C and hide it in the chest of drawers.
8. Temporarily dismantle the baseboards and open access to window frames, door frames, and the back surfaces of chairs, beds and sofas.
9. Remove interior decor, carpets, paintings from the walls, roll up rugs and clear the floor.
10. Leave drawers for clothes, if empty, open.

Before using hot fog against bedbugs and cockroaches, it is necessary to close all supply and exhaust ventilation ducts. In addition, neighbors should be notified about the upcoming disinfection. Residents of adjacent apartments must also block the ventilation holes in the bathroom and kitchen.

Pros and cons of hot fog treatment

The main advantage of the method is the high temperature. It is this feature that makes this type of disinfestation the most effective in the fight against adult bedbugs and eggs. Professionals have in their arsenal modern generators that can heat the insecticide to +90°C. This temperature is enough to destroy the eggs, which remain invulnerable to cold fog treatment.

Review.

Anna, Tver.

We treated dorm mattresses with hot fog. As soon as we checked in, we immediately realized that we would not sleep until we got rid of the insects. They called in professionals, as the scope of work was impressive. Exterminators carried out the treatment quickly, using hot fog. We are satisfied, everything was done efficiently and at a high level.

The fog, the effect of which has a detrimental effect on the life of bedbugs, quickly leads to their death, does not dissipate for a long time due to the high temperature. Over time, the cloud settles evenly on all surfaces. This is another advantage of this type of chemical disinsection - the parasites that were lucky enough not to die in the first minutes of treatment come into contact with the insecticide and are poisoned.

This method is not without its drawbacks.

• high cost;
• inability to use independently at home;
• treatment with hot fog for bedbugs sometimes takes a whole day, this is due to the long settling of the cloud.

The main disadvantage of this method is that it can be dangerous for the handler. To prevent this from happening, you must strictly follow safety regulations. Professionals have all the necessary protective clothing and know the rules for using generators. For beginners, it is quite dangerous to treat furniture against bedbugs using hot fog. Order a service from professionals, protect yourself and your loved ones from possible intoxication.

Review.

Peter, Moscow.

Hot fog treatment perfectly gets rid of bedbugs, because its high penetrating ability poisons all individuals and eggs and quickly kills them. Small particles penetrate everywhere, even into fleecy material. They stay there for a long time, maintaining their effectiveness for a long time.

Sanitary and Epidemiological Service

It is better to entrust the destruction of cockroaches in an apartment to a special service. Factors contributing to this:

• Specialists use professional equipment, which can be in the form of powerful generators or steam cleaners, and all equipment is certified, in good working order, and will not fail during the process;
• Exterminators know what a cockroach infestation is; based on their work experience, they quickly identify a cluster of insects; they are not afraid if there are a lot of them; in addition, when working they use protective suits that prevent the penetration of toxic substances into the human body;
• The substances used, thanks to which the destruction of cockroaches is carried out with cold fog, are inaccessible to the common person, they are located in the laboratories of the epidemiological service, they cannot be bought in a simple hardware store;
• Specialists using professional equipment will be able to spray toxic components in the most inaccessible places that a person cannot treat with his own efforts.

The Sanitary and Epidemiological Service accepts applications for the treatment of premises in different ways:

• Call the phone number during business hours, available information on the official website, leave a request, agree on the time of work;
• In the form of an application by email.

In addition, the epidemiological service accepts anonymous requests if a cluster of cockroaches is found in an apartment. In this case, specialists go to the specified address and carry out work; the consent of the apartment owners is not required for this.

Treatment for bedbugs with hot and cold fog generators in Moscow and the region is one of the most popular disinfection services. So how can you carry out competent, and most importantly, high-quality treatment against bedbugs in your apartment or at any other facility? In order to understand exactly what to do in your situation and what kind of treatment for bed bugs is required, we will consider several methods of disinsection (destruction) of insects using modern equipment.

• Hot fog in Moscow
• Cold fog in Moscow

Treating rooms against bedbugs with cold and hot fog in Moscow against bedbugs has long been firmly established in the lives of companies professionally involved in treating bedbugs. Modern technologies have replaced manual and balloon large-drop spraying, significantly simplifying and speeding up the treatment processes against bedbugs and other insects. Such methods of exterminating bedbugs in apartments in Moscow and other facilities have proven their effectiveness and are in demand on the market. But is everything as rosy as marketers of companies portray to us in pursuit of profit? Let's understand the pros and cons of treating rooms against bedbugs with hot and cold fog.

Although most people mistakenly call this procedure nothing more than disinfection of bedbugs with fog, do not follow their lead. Getting rid of insects is called disinfestation.

Cold fog treatment for bedbugs in an apartment in Moscow

How does cold fog affect bedbugs?

After spraying, the cloud with the active substance remains in the air for up to 1.5 hours. The smallest particles of poison spread throughout the apartment, penetrate into ventilation shafts, ceiling cracks, etc. The aerosol literally “envelops” the walls and floor with a film.

The toxic composition, entering the body of insects, leads to their death. The spectrum of action depends on the type of bedbug treatment used. In one treatment, you can remove not only arthropod bloodsuckers, but also cockroaches, ants and other insects.

The effectiveness of the work done is largely determined by the type of insecticide. Requirements for pesticides:

• Efficiency - bedbugs adapt to unfavorable conditions, and surviving individuals may no longer react to the same toxins; when re-processing, a new product must be used;
• Safety – it is advisable to check the availability of a certificate of no harmful effects on people;
• No pungent odor - some “aromas” of pesticides remain indoors for months;
• Spectrum of action - not all bedbug poison is effective against bedbug eggs.

It is better to entrust the choice of remedy to professionals who will help you buy an effective poison. The specialist takes into account the number of pests, the time of their appearance, the type of housing, the previous control method and other factors.

Cold fog - features of the method

Those who decided to get rid of pests and ordered the bed bugs cold fog leave only positive reviews about this technology. This modern method greatly simplifies and speeds up the destruction of insects. You should not tolerate their presence in the room or suffer from their painful bites; the prices set for the service of exterminating bedbugs with fog are low, affordable for everyone.

Disinfestation will not take much time. Due to its implementation, the client will not have to endure serious inconvenience. The products used belong to the fourth hazard class; they will not harm the property and health of those using the premises. Before specialists arrive to exterminate bedbugs with fog, the customer must complete the following simple steps:

• - empty the cabinets of dishes and food, remove all things from under the bathtub and sink;
• - furniture should be moved 15 centimeters from the walls;
• - remove personal belongings and toys from open places;
• — pets should be given to relatives, friends for a while, or taken out for a walk.

If you read the opinion of those who ordered the extermination of bedbugs with fog, they leave only positive reviews about the company’s work. You can treat a hostel, cottages, houses, offices, shops, almost any premises. The operating principle of the cold fog generator is as follows: under high pressure and the influence of aerodynamic force, a special solution is supplied to the nozzle. The liquid is reduced to a very small amount. It becomes only 50-150 microns in size. The operator can adjust this indicator.

The substance sprayed in this way completely fills the room. It gradually sinks and settles on furniture, floors, and all surfaces. By killing bedbugs with a cold fog generator, you can treat the most inaccessible places, even behind the baseboard. Pests have no chance to survive.

The generator is an electrically powered device, so it is preferable to use it than one that creates hot mist from bedbugs , because some difficulties arise due to its use. The room is filled with vapors of gasoline and exhaust gases, so it must be well ventilated.

Before ordering the extermination of bedbugs with cold fog, reviews about this technology can be read on the Internet, on the website. The only disadvantage of this technology is a temporary increase in humidity in the premises. This method is much more effective than spraying or the drip method. The operator does not need to make any special physical effort.

Which method of exterminating insects is better to choose, cold fog or hot fog for bedbugs , depends on the type of room, how it is used and for what. The company’s specialists will take into account all the nuances and help the client make a choice. Having ordered a cold mist for bedbugs, you can begin to use the room within 3-4 hours after treatment. There are many advantages to using this method. For these and many other reasons listed, the cold fog service for bedbugs has received only positive reviews.

Using generators, the company’s specialists will treat even hidden areas of the room very carefully. They will adjust the minimum spray to avoid excessive wetting of the sleeping areas. After treatment, it is guaranteed that there will be no pests left in any corner, behind baseboards, in ceilings, cracks, or furniture. If you want to see with your own eyes how the cold fog for bedbugs service is performed, a video of the work being performed can be viewed on the website.

It is recommended to carry out wet cleaning two, maximum three days after disinfestation. It will be necessary to ventilate the room and wipe down the furniture, all surfaces with which a person most often comes into contact. These are tables and cabinets, dishes. After the client understands all the intricacies of the cold fog service for bedbugs, what it is , how it is performed, and is convinced of its effectiveness, he can immediately contact the company’s managers and order it.

How to properly prepare a room for processing

Before you begin to exterminate bedbugs, cockroaches and other pests in a residential area using hot or cold fog, it is necessary to carry out preliminary preparation according to all the rules.

Before starting the disinfestation procedure, you must perform several sequential steps:

• securely hide all food products;
• place utensils, as well as hygiene products, in another room, and if this is impossible for some reason, provide them with airtight temporary packaging;
• In order for the aerosol product to work effectively, you must first perform a wet cleaning, which will remove dust from the floors, baseboards, jambs and other elements of the room;
• if there are paintings, framed photographs, carpets, as well as various decorative items on the walls, they must be removed;
• move all furniture away from the walls a few centimeters so that it can be securely covered with materials that do not allow droplets of aerosol chemicals to pass through;
• the room in which the procedure is performed must be closed.

While the room is being treated with cold or hot fog, no people or pets should be present. The person who is going to perform this work must wear closed protective clothing. In addition, it is important to take care of protecting the eyes, respiratory organs and skin - you will need a special mask and respirator.

Preparation for processing

To effectively destroy bedbugs, it is necessary to prepare the premises for treatment, namely:

• Take out or seal the dishes, etc.;
• Take out or seal all products;
• Move furniture away from the walls;
• Remove dust from the floor, baseboards, and other surfaces;
• It is recommended to remove decorations, paintings, and carpets from the walls;
• Remove people, pets, birds from the premises, take out the aquarium;
• The treatment of premises is carried out in special clothing and a respirator, and after finishing the work, clothes must be removed, washed hands and face, and taken a shower.

Security measures

Ensuring safety is the initial requirement for self-disinfestation. Professionals have special equipment in their arsenal: overalls, a respirator or gas mask, gloves, etc. Without personal protective equipment, there is a high probability of serious poisoning and allergic reactions.

Mandatory equipment for self-processing:

• A high-quality respirator - the particles of the insecticidal cloud are negligible; a regular cotton-gauze bandage will not protect the respiratory tract;
• Plastic glasses;
• Tight closed clothing, shoes;
• Gloves.

At the end of the work, clothes must be washed.

Important! If you feel the slightest discomfort or nausea, you should immediately leave the apartment, wash your hands, face, rinse your mouth and take activated charcoal. If the measures taken do not help, go to the hospital.

Hot fog treatment for bedbugs - advantages and disadvantages

It is almost impossible to destroy multiplied blood-sucking insects at once. Especially if you use sprayers or bulk insecticides. The small size of bloodsuckers gives them the opportunity to hide in small crevices and corners, and the high reproduction rate allows them to lay eggs in the most unexpected places. Therefore, killing bedbugs with fog becomes the most optimal option.

The effect of the method, treating an apartment against bedbugs with hot fog, is based not only on the spraying of toxic substances, but also on the direct effect of high temperature on insects. Bedbugs die at temperatures of 45°C and above, and this temperature has a detrimental effect on the pest in any phase of its life.

The treatment is carried out with special generators that heat the insecticide solution to 90°C and push a stream of steam through the bell. Fog generators are heated by liquid fuel and are therefore quite massive. Floor-standing, mobile versions of the Jumbo type can be used, consuming up to 9 liters of fuel per hour, or portable ones of the Airofog type, weighing 14 kg and with a consumption of 2 l/h, can also be used. The cost of exterminating bedbugs in Moscow using hot fog will depend on the area of ​​the room being treated.

What is good about disinfecting bedbugs with hot fog:

• steam microparticles measuring 5-25 microns, like air, penetrate into any pores and cracks;
• after 5-8 hours, in all places where the hot fog has penetrated, a film of a toxic substance remains, remaining active for 15-30 days;
• it is possible to select several insecticides depending on the degree of damage to the room and exclude products previously used in the treated area;
• The price for hot fog against bedbugs is affordable, and the effect of killing insects reaches 95%;
• residential buildings are treated with safe means;
• settling steam particles do not damage the coatings of furniture and finishing materials.

The disadvantages include:

• hot treatment against bedbugs is carried out only by trained specialists equipped with equipment and personal protective equipment;
• the need to leave housing for a time sufficient for the fog to completely settle;
• Thorough cleaning of open surfaces after completion of the procedure.

If there are allergy sufferers in the family, you can use hot steam treatment of the household without adding chemicals, but in this case, a repeat procedure may be required. On the other hand, if you have a strong desire to quickly get rid of insects and the high efficiency of hot fog treatment for bedbugs, the price no longer matters. Consumers who have used such methods of getting rid of bedbugs note a long period of its effectiveness - up to six months or more.

What is cold and hot fog?

“Fog” – finely dispersed drops of the working solution, sprayed using a generator. The insecticide is supplied from a reservoir under high pressure, which guarantees fine spraying with droplet sizes up to 5 microns. Depending on the temperature of the chemical supply, cold and hot fog are distinguished.

Cold fog disinfection involves using a liquid at room temperature and is useful for killing cockroaches, fleas and mold. Penetrating into the pores of furniture, wallpaper, hard-to-reach crevices and textiles, the chemical quickly and effectively destroys parasites along with their offspring.

The hot fog generator supplies the substance in a heated form (60-70˚C), which guarantees deeper and more targeted penetration of the insecticide into insect habitats. Hot fog treatment of residential and non-residential premises is used in the fight against all types of parasites, including bedbugs.

What is the difference between hot fog and cold fog?

In addition to the spray temperature, the fog differs according to several criteria, which are important to know before calling a disinfectant. The advantages of a hot fog generator are obvious:

• Finer atomization – droplet size is 3-30 microns. With cold spraying, 40-80 microns are achieved.
• Penetration into the most inaccessible places in the room.
• The ability to control the direction of the flow, since hot fog, unlike cold fog, is visible to the naked eye.

The cold fog generator has an undeniable advantage - the relatively low cost of the equipment. This directly affects the prices of companies that disinfect premises. If the company does the work conscientiously, then the destruction of mold, cockroaches or fleas with a cold mist is no less effective than with a hot one.

The scope of application of cold chemistry is much larger, due to the relatively low penetrating ability of the substance. Sometimes specialists refuse to carry out work where children and pets live. Especially when it comes to hot spraying. Cold fog treatment is possible almost anywhere where there is access to an electrical network that powers the generator.

Dry and liquid fog

Dry bed bug mist is the most advanced technology available. Baiting bedbugs using dry insecticidal fog is especially appropriate in apartments heavily crowded with furniture. The treatment procedure in this way allows you to get rid of parasites in one session.

Dry mist against bedbugs fills the entire area of ​​the room, and the remaining insecticide particles scattered throughout the room serve as a reliable barrier protection against the penetration of insects from neighboring rooms.

Various liquid insecticide options can be used using cold and hot generators. Treatment of a room with a hot or cold cloud is performed only by specialists.

Units for manipulating cold or hot insecticides are expensive, so purchasing them for home use is not possible, and there is no point in doing so.

How is processing carried out in Moscow?

Carrying out the treatment yourself seems difficult due to the need to use the necessary equipment and chemicals. In addition, each specialist takes precautions when carrying out stripping, and also provides customers with recommendations on further actions.

How the apartment or sequence of actions is processed:

1. Minimal preparation of the premises by residents for the arrival of a specialist: closing ventilation holes and windows, placing pets in, cleaning small interior items, cleaning bed linen.
2. An exterminator who arrives at the scene dismantles all secluded places in search of insect nests. To do this, furniture can be moved and disassembled, carpets removed, and wooden floors exposed.
3. At the end of the treatment, a short preservation of the room follows.

A specialist can conclude that some items are illiquid and need to be disposed of. Treatment for bedbugs is carried out not point-by-point, but throughout the entire space of the room. Staying next to a specialist in the same room while he is working is permissible only in a protective suit (but it is recommended to leave the room).

What is hot fog

Destruction of bedbugs with hot fog is carried out using generators. This involves more than just warming up the air in the room. Steam is created on the basis of liquids added to the generator, that is, the chemical base for killing bedbugs - insecticides.

The insecticide emulsion is diluted in water to a certain concentration. It is then added to the generator. The latter, during operation, turns the added liquid into fine droplets. Unlike a generator that uses cold fog, equipment with hot fog involves not just spraying the product into space, but heating it to a very high temperature. A curtain of fog is created, enveloping all corners of the room being treated. Spot treatment of an apartment with hot fog will not work due to its spread in all directions. It basically loses its meaning when there is a high level of bedbug infestation in the home.

Advantages of hot fog treatment for bedbugs

This type of disinfestation is characterized by the highest tariffs. However, technology guarantees the success of the event and often gets rid of bedbugs after the first visit of specialists. Therefore the price is justified.

Why choose this method and what is the reason for the effectiveness of disinfestation:

• there is a large processing area (the created curtain covers the entire space of the room);
• by creating a finely dispersed fog that falls for a long time into all small crevices, insect mortality is guaranteed;
• As a rule, an exterminator tries to use a complex of chemicals to create a hot fog, which also minimizes the chances of survival.

Exterminators, guided by the principle of safety of apartment residents, use solutions in generators that are not dangerous to people and pets. Hot fog has a large coverage area (unlike, for example, manual spraying with an aerosol or a cold fog), which allows the product to penetrate into all the nooks and crannies of the room.

How to treat bedbugs with cold fog

Today, treating a room with cold fog is one of the most common and effective methods of killing bedbugs. Disinfestation specialists carry out disinfestation using this particular technique, sometimes combining it with hot fog and other techniques.

Practice shows that cold fog provides the optimal combination of cost and efficiency of room treatment, as well as time consuming and safety for residents. Depending on the level of infestation of the apartment and house, using this technique you can remove bedbugs in just 1-2 hours.

Hot and cold fog: description, comparison

Destruction of bedbugs with fog
Outdated hand sprayers did not give the desired effect due to the size of the droplets of several hundred microns. Fog generators emit drugs, which will be discussed later, in a finely dispersed form. Thanks to this, they settle better on the surface and penetrate into the smallest cracks. Take a closer look at both methods:

• Cold: clouds of 35-80 microns emerge from the equipment nozzle. The indoor air remains dry. This guarantees the safety of wallpaper, furniture and other objects. The settling process takes 4 hours. This technology is most often used in apartments and houses. The reason is the compactness and availability of equipment. The result is almost always 100%;
• Hot: the generator produces particles 3-30 microns in size - this is already a gas. The settling process occurs within 10 hours - the effect is better. The method is relevant when processing large objects - warehouses, hangars, cinemas, etc. It is also used in residential areas. Equipment for exterminating bedbugs with hot fog is cumbersome and expensive, which is why the price of the service is 1.5-2 times higher.

Practice has shown that it is better to order a “cold” service for an ordinary apartment, while a mansion with a huge foyer and high ceilings can be properly treated using the second method.

Procedure for cold fog treatment

The essence of treating a room with cold fog is as follows:

• First, the prepared preparation is poured into a special apparatus - a cold fog generator. As a rule, an aqueous emulsion containing an effective insecticide is used;
• Then the device is turned on, and it begins to release jets of gas containing insecticide in finely dispersed form. Thanks to this, very small drops of the drug spread through the air, which along with it fall into all parts of the apartment, including penetrating into various holes and cracks where bedbugs often hide;
• Gradually, the product settles on all surfaces in the apartment, as well as on the bodies of insects. A certain dose of the drug, along with the air, immediately enters the spiracles of the parasites and penetrates first into the hemolymph, and then into the nerve ganglia. As a result, the insecticide acts on nerve cells and causes paralysis and death of the insect. If the dose of a substance that gets into the spiracle of a bug turns out to be insufficient, then it does not die immediately, but gradually the substance also begins to penetrate its body through the chitinous integument. Moving along treated surfaces, the parasite will absorb the drug, which will gradually lead to its death;
• The standard product used for pest control continues to act on insects for several weeks.

An example of such processing is shown in the video:

This principle of action is typical for most insecticides, regardless of whether they are distributed throughout the apartment using cold fog or sprayed through a regular spray bottle. The peculiarity of cold fog is that it ensures that the drug gets into hard-to-reach places, which is impossible when using a hand sprayer.

Benefits of cold fog

Compared to other methods, cold fog disinsection has a number of advantages, including:

• Possibility of using various liquid insecticides;
• Any surfaces are processed, including hard-to-reach ones;
• The disinfectant solution settles evenly and gradually;
• Economical use of drugs to have a positive effect on the cost of treatment;
• High safety indicators for people and animals.

The fog created by the generator has an ambient temperature, which gives the technology its name. The droplets settle completely within four hours.

Additional benefits of cold mist

The main advantage of cold fog is that it ensures that the drug remains suspended in the air for a long time. Thanks to this, the drug penetrates into all bedbug hiding places.

The technique allows the product to penetrate not only into hard-to-reach places, but also into the lairs of parasites, the existence of which people do not know. Bedbugs can live in cracks and holes in floors and walls, suspended ceilings, niches in furniture and other hidden places. Using a spray bottle, it is impossible to spray all the nooks and crannies of the apartment, whereas when distributing the product using a cold mist that penetrates everywhere, like gas or smoke, the insecticide is sprayed everywhere.

In addition, the cold fog generator produces a jet of steam under very high pressure. This facilitates the penetration of the insecticide even into the spaces between wallpaper and walls, behind baseboards and into winding crevices. Thanks to this, the efficiency of treating the room increases significantly, as does the likelihood that it will be possible to kill not only bed bugs, but also other parasites, for example, cockroaches and fleas, if they are present in the apartment.

For example, this is how cockroaches are poisoned in an ordinary apartment using cold fog:

Cold fog is much more effective than conventional spraying of an apartment with a hand-held spray bottle. One and its effectiveness can be increased. To do this, as a rule, a comprehensive disinfestation is carried out, which also involves the use of hot fog. This service is more expensive, but it allows you to remove parasites faster.

Cold and hot fog technologies complement each other. It is impossible to say that one of them is better or worse; both are effective. At the same time, hot fog is practically not used on its own; it is used for complex disinfestation.

What to choose: hot or cold mist?

The answer to this question should be given by specialists from the pest control company. Because despite the pros and cons of one or another method of killing bedbugs, each of them has its own subtleties and indications.

The specialist must inspect the room, identify the stage of development and the number of insects, and only after that make a decision about which technique will be appropriate in this case.

Although hot fog is considered one of the most effective ways to control bedbugs, it cannot always be used. This is due to what type of drug will be optimal for a particular case. Also, the choice is often influenced by the cost of the service. In any case, if you contact a pest control company, they will provide a guarantee for any treatment method and will certainly destroy all bedbugs and other insects.

What preparations are used to treat a room with cold fog?

To obtain cold fog, various products are used that are suitable for dilution in water. Preparations based on pyrethroids, neonicotinoids, organophosphorus compounds and other substances are mainly used. In each case, the drug is selected individually depending on the degree of infection of the room, the means used and the species composition of insects in the apartment. Quite often, at the same time as bedbugs, you have to poison other insects - silverfish, cockroaches, fleas.

Some bedbugs die while the apartment is being treated. If there are few of them in the room and during the disinfestation process it is possible to open all the shelters, then by the end of the treatment most of the parasites die. In a heavily infested apartment, where there is a lot of furniture and other things that allow insects to hide well, their poisoning may take longer. On average, it occurs within a few hours, but can last for a couple of days. Within a week, all bedbugs should disappear.

If 10-12 days after treatment the bugs begin to bite again, it means that their eggs have hatched into young larvae and they need to be re-pickled. This repeated treatment is also carried out using cold fog, but it is already simpler than the first, since there are fewer larvae in the room and they are more sensitive to the products.

Is it possible to use cold fog when treating yourself?

It is better to call professionals to treat your apartment with cold fog. To carry out such processing, a special generator is required, which is also called a fogger. The term comes from the English word "fog", translated meaning fog. The prices for such a device are quite high, so buying it for one-time use is impractical. A fogger should only be purchased by a specialist who is constantly engaged in baiting insects and whose device pays for itself fairly quickly.

Typical cold fog generator for sanitary disinsection.

As for the cost of services, treating a room with cold fog will cost almost the same as spraying an apartment yourself with a spray bottle, but the efficiency of professional work is much higher. To accurately get rid of insects, it is better to contact reliable and trusted companies.

The apartment must be prepared for treatment with cold fog in the same way as is done before disinsection by other methods. It is necessary to remove all objects from open surfaces, move furniture away from the walls, dismantle sofas and beds. It is important to find as many bedbug hiding places as possible. Cold fog kills bedbugs faster and more reliably than other technologies due to its high penetrating power. However, you should not expect that it will magically get rid of parasites in an unprepared apartment.

When the room is being processed, only specialists should be present in it. If the owners decide to stay, they must wear respirators. After the disinfestation is completed, the apartment must be left closed for at least 3 hours. Then it should be well ventilated. You can return home and lead a normal life on the same day. The drug used to bait insects ceases to be dangerous to people and pets after it settles on surfaces.

There is not a single case known where the products used would cause harm to residents or their pets if all safety rules were followed.

Cold fog from bedbugs

To process an apartment in this way, you need a special generator. Inside, its solution is fed into a chamber where a powerful air flow breaks the liquid into tiny particles. Through the hole, the fog is supplied outside at a temperature equal to the surrounding environment.

Since the temperature of the fog is low, the drops settle on the surface fairly quickly (about 3-4 hours).

Killing bedbugs with cold fog does not require special experience or skills. This process is quite simple and effective, but has some disadvantages.

Since the droplets of the product are quite large (compared to hot fog), the product cannot penetrate as effectively into all the distant spaces of the room. It is also not able to get inside furniture upholstery or behind tall cabinets that stand close to the wall. So there is a chance that after 2-3 weeks it will be necessary to re-treat to destroy the remaining insects.

Another disadvantage is high humidity. This has a negative impact on electronics and wiring. So for rooms where there is a lot of furniture, sources and consumers of electricity, it is better not to use this method.

How long does it take for bedbugs to die?

On the websites of sanitary and epidemiological services, there are often negative reviews that several days after cleaning, insects continue to bite and, therefore, the cold fog procedure is ineffective. This opinion arises due to ignorance of the stages of development of bedbugs. Most adults will die immediately after contact with the chemicals. But new ones may appear from the clutches after 3-4 days, and after two weeks they grow and begin to cause inconvenience to people.

One female lays about 20 eggs at a time. And not a single service will give you a guarantee that it has not put them aside, for example, in a distant outlet behind a closet. That is, new hatched and grown pests are biting you. Or you received parasites from neighbors whose apartment was also infested.

Therefore, experts advise not to carry out general cleaning for half a month, because the drugs used have a prolonged effect.

If after this period the insects still haunt you at night, then re-treatment with another insecticide is necessary.

Bedbugs die within half a month.

Further actions after disinfestation

After filling with chemical mist, the apartment is closed for at least 3 hours . If the parasites were poisoned using the hot method, this period increases to eight hours. Therefore, it is better to carry out this procedure in the evening, leaving the apartment closed at night.

After this, the room must be ventilated by opening windows and doors for 2 hours. General cleaning is carried out after 15-16 days. Before this, it is enough to wash only the surfaces with which residents come into contact with a soap-soda solution: kitchen tables, door handles, switches and dishes.

Floors, baseboards and walls are washed after two weeks. At the same time, curtains and bed linen from the closets are washed, and lighting fixtures are processed.

Repeated treatment is required if neighboring apartments are also infested with parasites. If disinfestation with cold fog was not effective enough, then you need to change the preparations or use another method in the form of temperature exposure.

Actions after processing

After the fog has completely settled, the premises must be thoroughly ventilated (at least one hour). After this, use a rag and a soap solution to clean areas that people often come into contact with (door handles, chairs, table tops, etc.). It is not recommended to wash surfaces with which contact is unlikely. Also, after treatment, you should not wash the floor for ten days, and it is better not to clean the walls and baseboards for a month.

Destruction of bedbugs with fog has only positive reviews, because insecticides in the form of a cloud make the treatment as effective as possible: a suspension of tiny particles is able to penetrate into the smallest gaps and crevices that bedbugs love so much, and destroys not only adults, but also their larvae. Consequently, the need for re-treatment, subject to preventive measures, is unlikely or will not arise soon. Read news and details about killing bedbugs with cold fog here.

Pros and cons of the method

“Foggy” disinfestation is a rather labor-intensive process. Preparing an apartment for processing and subsequent cleaning takes a lot of time and effort. The need to leave your home while the chemicals settle also causes a number of inconveniences. For residents exhausted by bites, the exposure time of the drug is often perceived as an eternity.

But, from the point of view of the effectiveness of exposure and the time of death of insects, it has no equal. The same fine-droplet spraying, which does not kill bloodsuckers, but only infects them, shows a weaker result and requires more time for complete cleaning.

The procedure for cold extermination of bedbugs is expensive relative to the purchase of dry chalk or aerosol. But, if you calculate how many cans of household poison it will take to treat an apartment, then the gain in price will not be significant.

Prevention

It should be noted that prevention will help keep the house clean and prevent the emergence of new colonies of insects.

Prevention of bedbugs is directly related to the reasons for their appearance, which are not always possible to establish. Bedbugs can come from anywhere: you can bring them on your clothes, bags and shoes; from troubled neighbors whose apartments are also contaminated; with the purchase of new furniture; on pet fur; Old books can also harbor bedbugs.

To prevent repeated pest control of bedbugs, you must:

• Do wet cleaning in the apartment at least once a week, keep the premises clean.
• Examine all floor surfaces in the house for holes and cracks, if any, they should be sealed with sealant.
• Be attentive to purchases of interior items, to your clothes and pets after a walk, to guests and neighbors, to recreational places (hotel rooms and other public places).
