Is Mashenka pencil dangerous for cats? Chalk Mashenka against cockroaches: an effective proven remedy

There are many products that protect our homes from harmful insects, but many housewives like the good old Mashenka chalk for its effectiveness and ease of use. This remedy has been known for a long time, and recommendations were passed on from mother to daughter: to draw white stripes along the floor and walls. This method is effective, but if you use only it, you will not get half the benefit from the popular insecticide. If you have already chosen white bars, try to reveal all their positive qualities when using them.

Chalk "Mashenka" for cockroaches - advantages and disadvantages of the drug

An inexpensive white block can solve the problem of harmful insects in an apartment where children or allergy sufferers live. The drug has earned many positive reviews. Consumers especially like the low toxicity to people and pets and the high efficiency in killing insects.

Positive qualities also include:

• low cost;
• no unpleasant odor;
• easy to apply to any materials and just as easy to wash off;
• helps against several types of insects.

Of course, any poisonous drug is dangerous for babies, who, crawling on the floor, can erase a line with a pen and then put their dirty fingers in their mouths. If there are small children in the apartment, draw lines only in places inaccessible to them. Adult cats and dogs are unlikely to lick crayon marks, and kittens and puppies may be interested in an incomprehensible pattern - protect them from contact with poison. It is most convenient to treat the apartment when the whole family and pets go to the country for several weeks; before they return, you will carry out a wet cleaning, collect dead insects with a vacuum cleaner - and there will be no dangerous traces left.

The drug “Mashenka” also has disadvantages. An apartment with white stripes on the walls and along the baseboards does not look very aesthetically pleasing. It is advisable to carry out the treatment at a time when guests rarely come to you. Users also note that the drug acts for a short time as a disadvantage. The lines have to be renewed periodically; the drug is destroyed especially quickly by sunlight.

Chalk "Mashenka" is not a brand, its name is not protected by copyright, and many companies produce this drug. Often negative reviews come from those who bought a block on the market cheaply, produced in an unknown place. Chalk is not that expensive; when purchasing, give preference to companies that specialize in producing insecticides and have earned a good reputation.

The effectiveness of the pencil against cockroaches and bedbugs is confirmed by its long-term presence on the insecticide market and numerous positive reviews

. The advantages of the drug include:

• ease of use;
• low toxicity;
• no odor;
• low cost.

The price of insecticide ranges from 10–30 rubles

. Thanks to this, all segments of the population can use the pencil for its intended purpose.

The disadvantages of the product include:

1. Low effectiveness in case of severe infection. If there are a large number of cockroaches and bedbugs in the room, chalk is unlikely to help. In this case, it is recommended to use a stronger agent.
2. Short validity period. The chalk begins to be active within a week and has a residual effect for about a month. However, sunlight and heat have a destructive effect on it. Therefore, the chalk lines must be updated every week.
3. Dangerous to use in a home with small children. The pencil's secure grip allows the poison to accumulate on the child's hands, from where it enters the baby's mouth. Therefore, surfaces that cannot be reached by children and animals should be treated.

Despite its shortcomings, the insecticidal chalk Mashenka against cockroaches and bedbugs does not lose its popularity

Chalk "Mashenka": instructions for use

Using the Mashenka chalk is very simple; it has the shape of a block, familiar to everyone since school. Do not rely on your skills, the instructions for use were written for a reason, you should read them. You can simply draw lines in places that are difficult for children to reach and inconspicuous, but there is no guarantee that active movement of insects will occur there. For maximum efficiency, outline the entire perimeter of the room with a continuous line at least 2 cm wide. Draw a closed outline along the baseboards on the floor and on the walls. Now the cockroach will not be able to leave or enter the room without touching the poisonous trail.

Treat utility entry points, ventilation openings, and window sills. If there are cracks or holes in the structures, draw a continuous closed outline around them. Draw a circle around hard-to-reach places where insects like to nest: the back walls of furniture, the interior cavities of cabinets and sofas. For convenience, you can chop the block and sprinkle powder on the places where pests accumulate.

When fighting harmful insects, you need to take precautions and protect yourself from contact with poison. When drawing the lines, you can open one edge of the package and hold the drug by the cellophane wrapper, but it is better to wear rubber gloves. Try to prevent particles of the drug from getting on your face: if you are crushing chalk or sprinkling powder on insect nests, it is advisable to protect your eyes with glasses. After work, wash your hands and face with soap, and only then can you touch food products.

How to properly use crayons against cockroaches

You can use a cockroach pencil in different ways:

• Clean up and thoroughly wipe away any dirt from the area where the lines will be drawn.
• Draw dense lines up to one and a half centimeters wide, crossing the expected paths of the cockroaches:

• along the perimeter of the entire living space on the floor along the baseboards;
• cabinets and shelves with food supplies in the kitchen, as well as mezzanines;
• walls and floor around the slab;
• draw a circle around the place where the trash can is located at a short distance from it;
• batteries and walls behind them;
• areas around the sink, toilet, bathtub and kitchen sink;
• the reverse side of hanging paintings, as well as pieces of furniture on the side adjacent to the wall;
• the perimeter of all walls and ceilings in the apartment.

• When carrying out this procedure in an apartment, it is also worth treating the common areas in the entrance:
• landings and flights;
• entrance to the basement;
• garbage chute location.

This treatment can guarantee the best effect in killing cockroaches in the apartment. It makes sense to unite with your neighbors and all at the same time take measures to eliminate the problem in all apartments of the building in order to avoid the reappearance of cockroaches.

Does Mashenka chalk help against ants?

Cockroaches and fleas may jump or fly over the drawn lines. Ants do not have such abilities, and a line 2 cm wide will become an insurmountable obstacle for them. They will bring pieces of the “delicacy” to the nest, feed all the inhabitants, and treat the female laying eggs. After some time, the entire family will be destroyed.

In the garden, you can sprinkle powder on the ground around the anthill. If there are aphids on the plants, make a water solution and spray the affected bushes with a spray bottle. This way you can deal with 2 types of pests at once. The same liquid composition can be poured directly into the anthill. Remove the top layer of soil and pour the powder or pour the liquid preparation into the place where insects accumulate. The principle of action of the drug in any form is absolutely the same.

Winning the fight against cockroaches is not easy, since these insects are very tenacious and easily adapt to various unfavorable conditions. But nowadays it has become easier to solve the problem, since there are many different drugs on sale to kill these harmful insects. A popular remedy is chalk for cockroaches, called by the manufacturers by the affectionate female name “Mashenka”.

Cockroaches are the scourge of many homes; picky insects can live in a country house, in an ordinary city apartment, or in luxury apartments. Insecticides, which come in a variety of forms, are successfully used to control insects.

One of the easiest to use and cheapest medications for cockroaches is the “Mashenka” chalk (pencil). At the same time, the product allows you to get a good result, especially if there are few insects in the house.

Description of the product

Chalk “Mashenka” is an insecticidal agent that has a contact effect, that is, in order for the insect to receive a dose of poison, it needs to come into contact with the surface treated with chalk.

The drug contains an effective insecticide - chlorpyrifos, but the main substance of the product is a cementing composition. When particles of the drug enter the digestive system of an insect, the cement blocks its functioning, resulting in the death of the insect.

Advice! You can buy Mashenka chalk in almost all hardware stores. The product is inexpensive, one pack is enough to treat 20-30 meters of area.

Packaging and appearance

Externally, the product looks like ordinary school white chalk, which does not have a distinct odor. Packaged in paper or polymer packs, decorated in blue tones. Instructions for use must be printed on the package. The weight of one package is 20 grams.

Storage conditions

To prevent the chalk from losing its insecticidal properties, it is important to store it correctly. Storage conditions:

• room temperature;
• lack of high humidity;
• no direct sunlight.

Advice! Chlorpyrifos is unstable to ultraviolet radiation, so Mashenka’s pencil should not be stored in places exposed to direct sunlight.

Safety

The product belongs to the IV (highest) safety class, that is, chalk is of low toxicity for humans, of course, unless you start using it internally in large quantities. However, you should not neglect basic security methods:

• The chalk should be stored in its original packaging away from food products;
• When using, it is not recommended to hold the pencil with bare hands; it is better to use gloves. You can apply the product by holding it through the packaging.

Storage conditions and safety

Mashenka chalk belongs to hazard class IV, it is low-toxic and generally safe for people. Externally, open chalk looks like ordinary school chalk, which is used to write on a blackboard and asphalt. Therefore, it is very important to think about storing the drug; choose places where children cannot find it.

You must not only hide the chalk from prying eyes, but also ensure that it is properly stored, otherwise the insecticide will very quickly lose its ability to fight cockroaches.

Conditions under which the product remains effective:

• Room temperature;
• Protection from high humidity;
• Protection from direct sunlight.

As mentioned above, you can only work with chalk while wearing gloves, and it is advisable to store it only in its original factory packaging. There should be no utensils or food products near the poison.

Application

Let's look at how you can use Mashenka's pencil to carry out pest control in your apartment.

Three ways

There are three different ways to carry out pest control using chalk:

• Drawing lines. This is the most popular and convenient method of use. The chalk is used for its intended purpose, that is, simply draw lines with it in those places where the paths of cockroaches pass, as well as near insect habitats.
• Use in crushed form. If you crush the pencil to a powder, the product can be used as a dust, that is, scatter it near places where cockroaches accumulate.
• Solution. Dilute one powdered chalk in five liters of water, use the prepared solution to wash surfaces - furniture, floors, plumbing items, pipes, etc.

Carrying out processing using the classical method

Since, most often, a pencil is used to draw lines in the habitats of cockroaches, let’s consider how to use this tool correctly so that the effect is maximum.

• Holding the chalk by the free edge, you need to draw continuous (not dotted!) lines. It should be remembered that this is a contact insecticide, so you should not give insects a chance to pass through the line without getting dirty.
• The following places need to be treated: thresholds, window sills, baseboards, ventilation grilles, places near sockets and switches located on the walls adjacent to neighboring apartments. It is imperative to treat the places where public building pipelines pass (sewage risers, heating system, water supply).

• It is useful to treat furniture from the inside. It is worth treating the shelves and drawers in cabinets and cabinets. It would not be superfluous to outline large furniture - sofas, chests of drawers, etc.
• It is imperative to carry out the treatment in the bathroom, draw lines at the places where the pipes pass, treat the space under the bathtub, make a line around the toilet.

The completed lines retain their properties for about a week, then the treatment can be repeated.

Mode of application

Mashenka against cockroaches can be used as follows:

• applied to the surface in the form of a chalk line;
• spray into places where insects accumulate after preliminary grinding;
• used as a solution.

The first option is most convenient, since in this case you won’t have to remove the apartment’s residents during the treatment, and you won’t need any special protective measures either. It is only necessary to ensure the continuity of the drawn line so that the insects are sure to cross it. It is best to apply a strip along the entire perimeter of the apartment, circling the baseboards and doorways with chalk. It would also be good to outline all the strategically important places for insects where they can gain access to food and water:

• trash cans;
• kitchen sink;
• cabinets with food supplies;
• fridge;
• dinner table;
• stove.

Its effectiveness will depend on the correct location for applying the drug. Therefore, before processing, it makes sense to inspect the apartment to detect nests of cockroaches and places of their greatest concentration.

If it is not possible to apply the product in a continuous line, for example, on an uneven surface, then it makes sense to crush it and scatter it in powder form. In this case, take the necessary protective measures. Rubber gloves are put on your hands, and your mouth and nose are covered with a gauze bandage so as not to accidentally inhale particles of the drug. This method is less preferable, since the risk of poisoning increases, and the adhesion strength to the treated surface is significantly reduced. However, as an additional treatment measure under baseboards and in hard-to-reach places, it is completely justified.

Mashenka chalk against cockroaches can be used in the form of a solution. To do this, the product, previously crushed to a powdery state, is diluted in 5-6 liters of warm water. The resulting solution is used to wipe the floor and all surfaces in the apartment. The advantage of this method is that the area of ​​the treated surface increases, however, the concentration of the toxic substance decreases, and the effectiveness of the drug decreases accordingly.

One package of the product is enough for approximately 30 m of the treated area if you plan to use it in the form of a chalk line. You will need two or even three times more powder. A solution prepared from one piece of chalk can be used to treat a medium-sized two-room apartment.

The effect of the pencil decreases after a week, so the treatment is repeated 7 days after the first, after first removing the remnants of the drug that has lost its activity with a damp cloth. Repeat the entire procedure as necessary until the insects are completely eliminated.

Interesting fact! It is unlikely that insecticidal chalk can be used as school chalk, since it has a softer structure and crumbles easily.

Is this remedy effective?

If the infection is severe, you should not use the product; you will need to select a more concentrated and effective insecticide and carry out a total treatment. As a preventative measure, Mashenka's pencil is very convenient. For example, if neighbors start poisoning cockroaches, then the insects will begin to actively crawl into adjacent apartments.

To protect yourself, it is worth drawing and regularly updating lines at places of general building communications - ventilation, pipelines, electrical wiring. You can use a pencil after a total treatment to prevent re-infection.

So, a cockroach pencil with the romantic name “Mashenka” is a fairly effective means of preventing cockroaches from entering your home. You can also use chalk if the premises are mildly infested. But if there are a lot of insects in the house, you should choose more “killer” products.

With which it is difficult for outdated pencils to compete. But not all products created decades ago are ready to lose ground. Cockroach chalk Mashenka confidently stands on the same shelves with the latest developments in this direction, in no way inferior to them in popularity. You can purchase it not only in Moscow, but also in any city in the country.

Active substance

The cockroach remedy Mashenka, despite its many years of existence on the market, is a modern drug: the manufacturer regularly makes changes to the composition, adding new, improved insecticides.

Chalk, which can be purchased today, contains the following substances:

• Deltamethrin. Poison of intestinal and contact action. It affects the nervous system when it comes into contact with the body, paws or stomach. Quickly leads to paralysis and death.
• Zeta – cypermethrin. It differs from the previous component in the structure and composition of the molecules. A synthetic substance from the group of pyrethroids.
• Chalk filler, which contains poison.

Cockroach chalk contains two different insecticides. This is done to prevent insects from developing resistance to the product.

Interesting!

If handled correctly, the likelihood of developing resistance to one insecticide is extremely low. To two at the same time - tends to zero.

Mashenka's cockroach pencil works in this way: the insect walks along the drawn strip, touching it with its paws, antennae, and abdomen. In contact with the smallest particles of water, the active components penetrate the insect’s cover and begin their destructive effect.

The main damage is caused by particles of the substance that enter the digestive system of the insect when it tries to clean the body parts stained with chalk with its jaws. Within a few minutes, the cockroach begins to behave unusually, after which it is paralyzed and death occurs. In order for cockroach chalk to fulfill its purpose, you just need to use it correctly.

We use Mashenka not only against cockroaches, but also against, and sometimes even helps. In general, we haven’t used anything other than chalk for many years. Cockroaches were removed many years ago and are no longer there. For prevention, we drew patterns from them in the kitchen in secluded places, and that’s all. Although there are crowds of neighbors. I was even ready to buy them these crayons myself - but no matter what, they think they are smarter.

Why Mashenka is good

The Mashenka pencil against cockroaches has a number of advantages, thanks to which millions of customers choose this product:

1. Chalk Mashenka against cockroaches, reviews of which may be mixed, effectively destroys cockroaches.
2. The low price of the pencil makes it accessible to all groups of the population. Even the cheapest products of a different type will cost more than Mashenka chalk.
3. This product does not generate dust, does not smell, does not emit toxins - it is safe to use. This is especially important for families with children or owners of furry pets.
4. It is very easy to wash off pencil streaks, unlike other cockroach medications.
5. Mashenka is well remembered from childhood. In those times when other means were unavailable or did not exist at all, it was Mashenka who helped get rid of cockroaches.

These reasons explain the fact that in many apartments today you can still find chalk strips around sinks, behind the refrigerator, and on the inside of kitchen cabinet doors. Often, close to the line drawn, there are corpses of those who underestimated the cockroach chalk.

Since childhood, I remembered that we always had these lines and stripes behind the refrigerator, around the sink and trash can, around the kitchen furniture, and in the toilet. Therefore, when I myself needed to remove cockroaches from the house, I immediately ran to the store for Mashenka. I thought it wouldn’t work today, because cockroaches mutate and adapt. But no, Mashenka did not disappoint, just like many years ago.

Dangerous sandbox

I remember well that as a child I very often spent time in the sandbox. My brother and I built entire sand castles and acted out battles with soldiers, tanks and other toys. The greatest danger was posed by black ants, which settled in the rotten wooden corner of the sandbox and periodically bit us, for which they were destroyed with childish mercilessness with a plastic spatula. In addition, there were sharp pebbles in the sand that could scratch your fingers.

While working as a pediatrician, I expanded my understanding of the potential dangers posed by sand (not counting quicksand, arid deserts, and construction accidents).

For example, I regularly communicate with parents of small children who are tasting sand. Here it is important to separate cases of curiosity - when a small child tries everything around, including sand. Usually, after several tastings, children understand that there is nothing pleasant about the taste of sand. However, some children experience a persistent perversion of taste. This can be due to a lack of certain substances in the body, for example, with iron deficiency anemia, zinc deficiency. And at an older age, persistent abnormal taste preferences may indicate the need to visit a psychologist or psychiatrist.

Experience shows that in addition to sand, completely unexpected things can appear in the sandbox. I once had a gloomy experience: the mother of one patient, a four-year-old boy Kolya, called me at nine in the evening and almost cried.

“Now I’m about to give Kolya a bath before bed, and he shows me a wound on his finger and says that he found a syringe near the sandbox and injected himself with it. What to do? -Where is the syringe? - I ask. - I don’t know where. On some playground, where he and the nanny walked during the day... - So, where is the nanny? - So it’s already 9 pm - I’ve probably been home for a long time. — The chance of possible infection is certainly very low. But theoretically it exists. If you want to play it safe, I say, you need... that same syringe. For analysis.

Then mom put Kolya to bed. Today she somehow especially, diligently and with expression read a book to him, he soon fell asleep. Before turning off the light, she looked at his sweet face for a long time, with tenderness. Suddenly he pulled his hand out from under the blanket, and mom again saw his little ring finger - with a wound from the damned syringe. She stood up abruptly, turned off the light and left the apartment. She rushed by car to the nanny's house.

Flaws

No matter how good the drug is, it has some disadvantages:

• short validity period - strips must be regularly updated so that they do not lose effectiveness;
• an insufficient effect is possible if the apartment is heavily infested;
• Inhalation of insecticide particles by animals may result in poisoning.

When applying chalk, you should wear a medical mask or respirator and gloves. After work, wash your hands thoroughly with soap.

How to use it correctly

There is nothing complicated about using Mashenka to fight cockroaches. It is necessary to apply stripes in those places that are especially often visited by cockroaches: behind the refrigerator, around heating pipes or appliances, at the sink, near the trash can. All necessary places are indicated on the packaging of the chalk.

Rules of application:

• Draw lines on baseboards and back panels of furniture. This should be done especially carefully on kitchen furniture. If possible, mark the entire perimeter of the rear panel.
• Enclose the trash can in a chalk ring. Make sure that the bucket always stands inside the circle.
• Make markings around the entire perimeter of the sink. Mainly, it is from this source that cockroaches quench their thirst.
• Outline the perimeters of all ventilation ducts.
• Surround the legs of the tables with a chalk pattern so that an insect, crawling onto the table, is forced to walk on the chalk.

The stripes should be thick so that cockroaches cannot step over them, but pass with all their legs. The price of chalk is low, so saving is inappropriate here.

The number of Prussians destroyed by chalk depends on the timing of its use: the longer the “drawings” are left undisturbed, the longer they will destroy arthropods. You should not remove the strips until the cockroaches are completely gone. Treatment should be repeated until the cockroaches disappear. Only there can one be sure that man and means have defeated the most ancient creatures on earth.

I still remember how my mother regularly bought a Chinese anti-cockroach pencil at the market. They died almost instantly. Now that I was faced with such a problem, I didn’t think that I would find a piece of chalk. didn't help. I was preparing to buy expensive sprays and gels, although I don’t really believe in their effectiveness. And suddenly in the store I see Mashenka’s pencil, similar to the one I remember! I was glad to see him, like an old friend. I immediately bought a year's supply. True, I used it very generously, so my supply was significantly reduced. I smeared everything possible, making sure not to apply it in the most noticeable places. And now I’ve been living peacefully for a month now. There are no old cockroaches left, and I am no longer afraid of new ones.

You can use both chemicals and folk remedies, the main thing is to start exterminating the Prussians immediately after their appearance. Cockroach chalk Mashenka has been used for several decades to successfully remove red cockroaches.

Many owners of infested apartments believe that Mashenka is the one who will most effectively deal with mustachioed insects.

Insects that occupy an apartment usually plunge the owners of the premises into shock, because the family of pests multiplies quickly.

Without taking immediate action, unexpected “tenants” will fill the entire home, threatening to displace the inhabitants.

Most often, cockroaches encroach on the territory, attracted by the large amount of food and moisture necessary for life.

Chalk Mashenka is a small gray pencil.

The weight of the bar is about 20 grams, but this is enough to treat a small room against cockroaches.

Manufacturer – Russia.

• deltamethrin;
• gypsum (helps keep its shape and not crumble during use);
• zeta cypermethrin (insecticide).

The packaging of the chalk is waterproof, which allows it to be stored for a long time without losing its properties that are harmful to the Prussians (provided that all storage rules required by the manufacturers are followed).

The active ingredients of the drug are the latest pyrethroids, which act only upon contact.

It is enough for an insect to run over the product applied to the surface so that a few particles of the toxic substance remain on its limbs.

From the extremities, insecticides certainly enter the oral cavity, then into the intestines (Mashenka chalk also tends to be absorbed through the body).

The poison spreads in the body of the barbel instantly and begins to act. First, a malfunction occurs in the nervous system, after which important organs for life stop functioning.

The death of the Prussians occurs after complete paralysis. This happens literally a few hours after the insecticides penetrate the body of the mustachioed “tenant.”

Another significant plus is that an infected cockroach can spread a toxic substance, because it manages to return to the nest, where it comes into contact with several fellow tribesmen.

The insecticide particles continue to act, infecting other longhorned beetles along the chain. Mass death of red “neighbors” occurs 3-5 days after exposure to the pencil.

When the home is not heavily infected, it will take about a month to completely exterminate the Prussians. During this time, several treatments may be necessary, this will significantly increase efficiency.

Home preparation

Be sure to paint stripes on door frames and even window frames. It is also important to block all approaches to objects attractive to cockroaches:

• kitchen stove;
• trash cans;
• dining table;
• refrigerator;
• kitchen sink;
• bedside tables with food supplies.

Often new “guests” enter an apartment cleared of cockroaches, especially if they are infested with pests.

You can stop all attempts by barbels to develop new territories by applying cockroach chalk around all cracks in the walls, ventilation ducts, and pipes.

Such prevention will allow you to keep your home clean for a long time, and by making it a rule to regularly apply the product, whiskered insects will probably no longer bother you.

When the surfaces are not very smooth and it is difficult to draw a wide, continuous line, it is better to use the second method of using chalk - scattering crumbs.

The drug crumbles well, but be sure to do this with rubber gloves.

A mask won’t hurt either, because it’s very easy to inhale small particles, and the consequences can be quite unpredictable, and a mild allergy is only the most harmless nuisance.

To prepare the solution you only need one chalk; it is enough for 5 liters of water. Crumble the pencil first, as it does not dissolve well in liquids.

• The advantage of this method is that you can process a considerable area.
• The downside is that some of the destructive properties of the insecticide are lost, which will affect the effectiveness.

Pencil Mashenka conscientiously poisons the barbels for only a week; after this period, she will have to re-arm herself with chalk and draw lines.

It is better to remove old stripes first; toxic substances have almost no effect. The lines are wiped with a regular wet cloth; you don’t even need to use detergents.

pros

Chalk Mashenka has many advantages, thanks to which it has remained at the peak of popularity for decades, in the ranking of owners of apartments infested with cockroaches.

The main advantages of breeding a Russian family with a pencil:

• convenient use (it is enough to remove the wrapper so that the “weapon” is completely ready for use);
• low, almost harmless toxicity for humans (the applied substance does not evaporate into the air, it acts only upon contact);
• there is no smell at all;
• the cost is several times less than the price of aerosols or spray.

It is thanks to its shape that chalk is considered the easiest to use.

After all, comparing it with liquids or aerosols, before using which you will have to remove all the inhabitants from the apartment, the pencil can be considered a real savior, because it will not harm even small pets.

Another important plus is that it goes well with all kinds of drugs from the red family.

If you first apply the stripes with a pencil, and then use an aerosol or working solution, then you can actually completely get rid of unwanted “tenants” in just one go, because the surviving individuals will certainly sooner or later run over the applied chalk.

When using chalk in combination with an aerosol, you should keep in mind: they do not affect the eggs, and in a few weeks young representatives of the cockroach family will appear in the home.

Here you cannot do without prolonged exposure to the pencil - it is better to regularly update the stripes for 2-4 months.

Minuses

Of course, the advantages of a crayon are obvious, but you also need to be aware of the disadvantages, especially before using a pencil.

Despite the assurances of manufacturers that the effective remedy acts on baleen insects for almost a month, it should be taken into account: perhaps this is only in a dry and dark room.

Sunlight and humidity destroy the toxic substance, and within a week cockroaches will be able to run on it completely safely.

If the room is heavily infested, you should also think carefully about how effective the use of chalk will be.

Typically, it can take many months to destroy an entire Prussian family. It should be taken into account: new larvae will appear from numerous eggs, and a pencil simply will not cope with so many pests.

It is better to spend money on a more effective drug, or use chalk as an additional remedy.

The last disadvantage of using it is that it is better to apply it in inaccessible places, especially when there are pets or children in the room.

Chalk Mashenka tends to accumulate on the hands, and if a child swallows a considerable amount of insecticide, despite its low toxicity, this can lead to poisoning.

If such a nuisance occurs and alarming symptoms are observed in the form of nausea, loss of consciousness, you should not delay medical help.

Using Mashenka chalk against domestic cockroaches is a fairly common method of control, but it is better to first think carefully about whether you can get rid of it with its help.

If the infection of the apartment is severe, it is better to use more aggressive drugs. This will allow, the result of which will still be a turn to powerful insecticides.

Special crayons can be called quite effective means for fighting Prussians. Mashenka's anti-cockroach pencil has proven itself well. On the Internet you can find mostly only positive reviews about it. Why do many people consider this chalk ideal, and how is effectiveness achieved?

How does cockroach chalk work?

Insects are exposed to active substances through direct contact with the insecticide. The cockroach touches the chalk strip and the drug gets onto its body. The poison does not act immediately, but after several hours. It gradually penetrates the body through the chitinous membrane. During this time, the cockroach manages to get to its nest with its relatives and infect them. The active substances have a detrimental effect on the nervous system of insects, blocking its impulses and causing paralysis and then death.

The effectiveness of chalk against cockroaches

The effectiveness of chalk is quite comparable to the level of its toxicity. Unlike aerosols sprayed to fight cockroaches, chalk fights the invasion of uninvited guests for a long time, even in the presence of the owners. They can calmly stay at home, and at this time the chalk will perform its function, killing more and more insects.

A pencil will not remove cockroaches once and for all; harmful insects may appear again after a while. But if you use it regularly, you can be sure that you will not encounter any uninvited guests at home. Numerous positive consumer reviews confirm the effectiveness of its work.

To work effectively, it is necessary to use the drug with a valid expiration date and, when applying it, act strictly according to the instructions.

How long does cockroach chalk work?

Once applied to surfaces, toxic substances last for about a week. Then, under the influence of external factors, they gradually lose their properties, becoming less effective, and they can even crumble off walls and other inclined surfaces.

Manufacturers recommend re-treating all cockroach paths 7-14 days after the previous application. It is not enough to simply draw lines in the same places. It is necessary to thoroughly wash the surfaces where the drug was previously applied, and then draw new ones.

Are crayons dangerous for humans and animals?

Despite the fact that the active ingredients of this product belong to toxicity class 4, and being in the same room with them is harmless, manufacturers do not recommend using cockroach pencils in rooms with small children or pets. Although crayons are used in inaccessible places, there is always a risk that the poison will enter the body of a baby or pet.

Unused crayons should be stored where they cannot be found by the youngest members of the family. The beautiful wrapper resembles candy, and the child can taste the crayon. Despite the bitter taste of most crayons, which is unlikely to please pets, a cat or dog can chew the packaging while playing with it and receive a dose of poison.

Composition and appearance

The manufacturer is Russia, but Mashenka chalk for cockroaches is an analogue of a Chinese-made insecticide, also popular and highly effective in the country of porcelain.

The pencil consists of chalk, gypsum and two toxic substances - deltamethrin and zeta-cypermethrin. Both of them are contact poisons, toxic to animals and people, and therefore this drug is assigned a 4th degree of danger.

Why are there plaster and chalk in the composition? These simple components, in turn, are binders and are necessary for attaching the poison to the surface, so that the activity is maintained for a long time.
