Operating principle

Pencil Mashenka against bedbugs and other insects begins its poisoning effect upon direct contact with them. Insecticides penetrate the outer shell of the pests and destroy impulses going to the muscles from the nerve nodes. After this, paralysis and death of the insect .

The effect of the chalk begins some time after the room has been treated. By touching the drug applied to the surface, the cockroach or bedbug becomes infected and infects other insects. The number of pests in the house begins to decrease after 3–5 days. Their twisted corpses can be found on the floor. With the help of Mashenka's chalk, the entire colony can be destroyed in two to four weeks. During this period, repeated treatments will need to be carried out every seven days.

Instructions for use

You can get rid of bedbugs, cockroaches and ants once and for all if you use the insecticide correctly.

2. Furniture is moved away from the walls and the room is wet cleaned. To block escape routes, door frames, ventilation grilles and windows are washed with a strong bleach solution. As soon as the moisture has dried, you can begin treating the room.

One pencil will be enough to cover a surface area of ​​30 square meters. m.

Room treatment

Before using Mashenka chalk, it is recommended to wear protective equipment. Hands must be protected with rubber gloves.

There are three ways to use an insecticidal pencil

1. Simple lines. Various lines 1–2 cm thick are drawn on the surface with chalk. In places where insects accumulate, the lines are made even thicker. All joints and cracks are processed. Particular attention is paid to the interior spaces of the furniture.
2. Grated chalk. Using Mashenka pencil powder is a fairly effective way to kill bedbugs, cockroaches, and ants. The chalk must be crushed so that the powder resembles flour or soda. It is poured into electronics, books and other things that cannot be sprayed with aerosols. After the pests are destroyed, the powder is removed using a vacuum cleaner.
3. Solution. The prepared powder can be dissolved in water and applied using a spray bottle. It is used to treat all habitats of bedbugs and cockroaches. The solution can be poured behind radiators, baseboards and into various crevices. It is not recommended to spray wallpaper with it. Washable wallpaper will then take a long time to wash, but paper wallpaper may come off.

The effectiveness of the treatment also depends on the correct location for application of the drug. Therefore, the apartment should first be carefully inspected in order to identify the places of greatest concentration of cockroaches, bedbugs, and ants.

Be sure to outline with chalk those places where insects can gain access to food and water:

• kitchen sink;
• trash cans;
• stove;
• dinner table;
• fridge;
• cabinets in the kitchen.

How long does a cockroach pencil last?

Many people do not know how this chalk works and how long it remains effective. A Chinese pencil against specific types of cockroaches is effective for 7-10 days.

After this time, the tenant carries out 1 more sanitation.

The fact is that in 7-10 days such a poison quickly loses its useful specific properties.

At the same time, such chalk often falls off walls or from various inclined surfaces, which also reduces its effectiveness.

Manufacturers of chalk pencil recommend that residents, after 7-14 days, first carry out wet cleaning, and then apply fresh, rather than outdated, insecticidal chalk to the baseboard or other surfaces.

Advantages and disadvantages of the drug

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 an 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 . All the disadvantages cover its many advantages and effectiveness.

The main mistakes in using insecticidal chalk

Despite the fact that the cockroach chalk pencil is very easy to use, many people make a number of mistakes when using it.

In such a situation, residents perform the following incorrect actions:

• They save too much on such a pencil from China. Many people, in order to save it, make the lines not thick and solid, but thin or dotted. Thus, they automatically reduce the effectiveness of such a drug;
• combine cockroach pencils with other insecticidal agents. Many residents, in addition to chalk pencil, apply various fragrant herbs to the infected surfaces, which repel parasites. However, in this case, the insecticidal chalk also becomes ineffective;
• Pencils are not stored correctly to prevent cockroaches. Sometimes people store it next to food or in low cabinets where small children can find it. Such an oversight should also not be allowed;
• do not carry out wet cleaning after completing the sanitation of their home. This is also a gross mistake, which often leads to poisoning of pets (cats, dogs, etc.) and humans.

Therefore, after sanitizing the apartment, it is imperative to remove the remains of chalk pencil from specific apartment surfaces.

Reviews on the use of Mashenka chalk against bedbugs

We rented a new apartment, which turned out to be infested with bedbugs. They were everywhere - in the old sofa and under the wallpaper. At night the parasites bit us and our three-year-old child. We wanted to rent another apartment, but our parents advised us to try decorating the rooms with Mashenka’s pencil. It is inexpensive and is available in every hardware store. We moved all the furniture away and went to spend the night with my mother. And my husband smeared chalk on all surfaces and furniture. The bedbugs disappeared after just three days . Now I use Mashenka for prevention. We always have this product in our house.

Marina, Russia

As the weather warmed up, we arrived at the dacha and discovered bedbugs. We didn’t buy any new products, but decided to resort to the old, proven Mashenka chalk. A week before the vacation, they covered all the rooms with it. The two weeks of rest passed quietly. Only mosquitoes bit us.

Alexandra, Samara

Our house is always clean, but then in the morning we started waking up bitten. It didn't look like mosquito bites, and I thought to look under the mattress. There were a lot of bedbugs underneath him. It’s unclear where they came from, since our neighbors are normal. I immediately sat down at the computer and began looking for information on how to deal with them. My parents remembered Mashenka’s chalk, which used to help against various insects, and I read that parasites do not like the smell of wormwood. I bought a pencil and spread wormwood. After treatment, the bedbugs disappeared two weeks later .

Folk remedies for bedbugs in the apartment

Double-sided tape - it is necessary to paste over the internal parts of furniture (bedside tables, wardrobes, beds), checking the results from time to time. Insects stick well to the surface of the tape.

Water baths are homemade traps placed at the foot of beds. In a deep bowl (about 6 cm), you need to fill the water halfway and place it under each leg of the sofa or bed.

The use of such methods as Mashenka's chalk will help in the fight against adult individuals that somehow accidentally ended up in your apartment. It will not be possible to destroy a bedbug nest using a trap or a small bag. To do this, we need more modern means, such as dichlorvos and other aerosols that have a suffocating effect. This contributes to the extermination of parasite nests and prevents the larvae from hatching from the eggs, continuing to increase the population size.

Reviews about the use of cockroach repellent

Only two days have passed since treating my apartment with Mashenka chalk, and there are already much fewer cockroaches. I hope that after a while they will disappear completely. I really liked this insecticide. It is easy to use and very cheap. Pencil - for those who are bothered by bedbugs, fleas, ants, cockroaches, moths. It is used to treat walls, baseboards, sinks, furniture, tiles, mattresses, and paintings. Chalk has one drawback - after processing, the lines drawn by it are visible on the surfaces.

Katerina, Kazakhstan

During the renovation of the apartment, cockroaches appeared in our house along with the purchased building materials. I am very afraid of these , so I immediately ran to the nearest supermarket to buy poison. There was nothing suitable on the store shelves. Apparently, cockroaches appeared not only in our apartment.

In a private store I was offered to try to get rid of pests using Mashenka chalk. Its price is very low, so I doubted it, but bought it. At home, I put on rubber gloves and, armed with a pencil, outlined all the building materials with thick lines. After a while, the cockroaches disappeared, and I washed off the traces of the chalk with a damp cloth. I recommend this product to everyone if insects have just appeared in your home. If they have already multiplied, then a stronger drug will be needed.

Antonina, Ukraine

In a rented apartment, we encountered cockroaches that were poisoned with everything! We tried various aerosols, gels, traps. But nothing helped. We decided to resort to old, well-known and cheap means – Dichlorvos and Mashenka’s pencil. We were pleased with the result .
We no longer think about insects. Lyubov, Ukraine

Ant chalk

Very often, owners of country houses or apartments located on the ground floor are faced with the problem of ants. They do not bring any harm to people, but they can seriously spoil food. Chalk Mashenka in this case will be an ideal option to help get rid of them.

If we talk about the disposal procedure itself, it is almost identical to that with cockroaches. But goosebumps are much easier to deal with. It's all about their nature and habits, unlike cockroaches, which run chaotically around the territory and scatter in all directions, ants choose their route and strictly follow it. Therefore, you need to use Mashenka’s chalk in the following way: draw lines that intersect their route.

It is very easy to figure out which way they move every day; it is enough to follow at least a few insects. You can use another method for those who do not have time to do surveillance. They have a sweet tooth and love sweets very much, so put a little honey or syrup, for example, in a certain place, and draw a circle around it. They will definitely touch the line and bring the substance to their nest.

Many people do it differently. You can look for an anthill near your house and sprinkle it with powder. The powder can be crushed into chalk. You can also pour a solution over anthills; to do this, chalk is diluted in water. The effect is absolutely the same.

Effect of the drug

Insert your text hereChalk and gypsum in the Mashenka pencil are only auxiliary substances.
Among the insecticidal components that have a detrimental effect on bedbugs are:

• Zeta-cypermethrin is used in the fight against household pests. The substance affects the nervous system of insects.
• Deltamethrin complements the action of zeta-cypermethrin.

These substances are considered the most effective blockers of the nervous system; they paralyze and lead to the death of bedbugs.
The chalk acts like a virus, which manages to transmit the bug to its relatives even before its death. The form of the drug Mashenka and its composition explain the specifics of the insecticide. Do not expect an immediate effect from using the product. The chalk kills most insects within a few days. The drugs retain their activity because they are resistant to weathering and moisture.

Insecticide composition

The twenty-gram Mashenka pencil looks like an ordinary school block of chalk. It is sold in plastic bags in all hardware stores. In addition to gypsum and chalk itself, this popular insecticide, as the name suggests, contains two toxic substances. Thanks to the plasticity of gypsum and chalk, the product is easily applied to surfaces that need to be treated against bedbugs.

Deltamethrin 0.05%

Deltamethrin is an insecticide belonging to the pyrethroid family. Pyrethroids are man-made versions of pyrethrins, natural insecticides found in chrysanthemum flowers. Deltamethrin is commonly used outdoors on lawns, ornamental gardens, golf courses, and indoors to treat cracks and cracks where bed bugs hide.

Deltamethrin was first described in 1974 and came to market in 1978. It is included in numerous products used to kill a wide range of insects. Deltamethrin can often be included in insecticidal products in the form of aerosols, sprays, and powders. Mashenka chalk, which contains Deltamethrin as an active ingredient, is very popular in Russia.

Cypermethrin was originally developed to control bedbugs on agricultural lands, and was also used to kill ectoparasites (lice, fleas, various ticks) that affect cattle, sheep and poultry. Subsequently, it became available to household consumers and was included in many household products, including the “Mashenka” chalk.

Penetrates the insect's body and paralyzes it.

Deltamethrin can kill insects by direct contact or if they eat it. This disrupts their normal nervous system function. It is less toxic to mammals due to their higher body temperature, larger size, and reduced sensitivity to the chemical.

On the one hand, this is a powerful weapon for protecting your home from insects, but on the other hand, this substance is one of the ten most severe toxic substances, along with DDT, hydrocyanic acid, and chlordane. Of course, its concentration in chalk is extremely low, but we must remember that it strongly depresses the nervous system.

The composition contains deltamethrin and zeta-cypermethrin as active substances.

Chalk and gypsum are auxiliary materials that simplify the process of using the drug and give it shape. Occupies more than 90% of the composition.

The anti-cockroach pencil is intended to help in pest control, as a primary or additional tool. The mechanism of action of the active substances is based on direct contact with insects. Once in the body of arthropods, the poison interferes with the conduction of impulses from the nerve nodes to the muscles, causing complete paralysis, which, in turn, leads to death.

One bar of “Mashenka” against cockroaches is usually enough for a small room. On average, to process an apartment or house, you should stock up on 4-5 pieces. Lines that are not in direct sunlight, but in the shade or covered pieces of furniture, retain their active properties for up to 4 weeks.

Instructions for use

There are three main ways to use Mashenka:

• Directly like chalk, which is used to draw lines on the surface being treated.
• As a powder, which is obtained by crushing chalk.
• In the form of a solution for wet processing.

These methods are no different in effectiveness.

Thick stripes are applied to the surfaces to be treated - from 2 to 4 cm in width. Traces of chalk leave:

• along the perimeter of the room along the baseboards;
• on the back surfaces and bottom of furniture;
• on the back of the paintings;
• in places where wallpaper has peeled off the walls.

Possible cracks and crevices in the floor are treated with a concentrated slurry, which is obtained by dissolving fine powder in water. You can expect final results from the treatment within a few weeks. After 4-6 weeks, the pencil marks are washed off with a soap and soda solution. It is important to store the drug correctly, since its substances lose activity when exposed to sunlight.
