You can use both chemicals and folk remedies, the main thing is to start destroying 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 - a small pencil gray.

The weight of the bar is about 20 grams, but this is enough for processing small room from 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 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 draw 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.

Cons

Of course, the advantages of a chalk 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.

Better to spend more effective drug, or use chalk as an additional tool.

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.

Insect chalks gained great popularity back in Soviet times. With their help, residents apartment buildings removed cockroaches, ants, bedbugs, moths and other unwanted living creatures from indoors. The chalk was convenient to use - just like regular school chalk, and unlike most other household insecticidal preparations, it did not have a specific odor.

In addition, the chalk itself was perceived as somehow positive and with a small amount of humor.

Maybe it was the quality of the composition or the convenient form of the product, but Mashenka’s chalk against bedbugs turned out to be no less effective than against cockroaches, and saved more than one family from these harmful and annoying insects. Now it can also be found on store shelves and market displays next to other, more modern means.

It must be said that the Mashenka chalk continues to enjoy stable popularity. This is not surprising, because it is very easy to use and non-toxic for people and animals. You can use it not only to kill insects, but also to prevent their appearance: for example, if your neighbors have bedbugs and can move away from them.

Composition of the product

Chalk Mashenka consists of only four components, two of which are auxiliary (chalk and gypsum). The active ingredients of the product are:

Of all the substances in the pyrethroid group, it is Cypermethrin and Deltamethrin that are the most effective blockers of nerve transmission in the body of insects. It is thanks to them that Mashenka is so highly effective.

Due to the consistency of the chalk, the applied substances are clearly fixed on the surface and are not erased from it. When a bug comes into contact with the treated surface, the poison enters its paws, and then through the proboscis into the digestive system. Having already been absorbed into the blood in the body, it begins to work.

If an infected bug touches another individual before it dies, it will also be poisoned. Thanks to this, Mashenka works according to the “viral” principle.

Feedback on using Mashenka chalk:

When we noticed bedbugs at the dacha, we decided to do it the old fashioned way and covered all the rooms with Mashenka’s pencil a week before our vacation. The chalk helped again: not a single bug bit us in two weeks. Only mosquitoes tormented me...

Alexandra, Samara

The toxic substances in Mashenka chalk have an active effect within 4-6 weeks after application.

Note:

Unlike most other insecticides, Mashenka’s components are quite resistant to weathering and moisture. Therefore, the chalk, being smeared on the surface, retains its activity for a long time. But these same properties require the protection of small children in the house.

Rules for using Mashenka chalk

Unused or started product must be stored in dark place, since its active substances tend to disintegrate when exposed to sunlight.

Depending on preferences and type of room, you can use one of three methods:

• directly “drawing” with chalk;
• dusting with crushed chalk (this method is the most toxic due to the risk of inhaling dust);
• wet treatment - coating the room with chalk dissolved in water.

There are no fundamental differences in effectiveness depending on the method of use of the chalk. The easiest and fastest way, of course, is to treat the room with a crayon stick. When fighting bed bugs, one pencil is enough for a room of 30 square meters.

It is advisable to wear protective gloves, especially if you plan to use several crayons at a time. After finishing the treatment, hands and face must be washed with soap. If dust from the product gets into your eyes, rinse them thoroughly with running water.

When fighting bed bugs, it is advisable to move furniture away from the walls in advance and check the baseboards for cracks and peeling. This is where bedbugs can live. It is necessary to remove the paintings from the walls, as they will also be processed. If it is possible to disassemble the sofa or bed down to the base (solid base), this should also be done.

Another review:

"When we entered new apartment, then they were horrified! There were bedbugs everywhere - in the wallpaper and on the sofa. They also bit us and a small child (3 years old). We thought about running away from there as soon as possible, but my parents recommended Mashenka’s pencil against bedbugs. It's cheap and sold everywhere. My husband sent us to my mother, and he moved all the furniture and smeared it everywhere. Believe it or not, after 2-3 days the whole misfortune was over. Although I keep the chalk just in case and periodically smear it for prevention.”

Marina, Moscow

Before use, you must empty the chalk from the packaging, leaving its lower part. It should be taken precisely by this half protected by polyethylene. Then the necessary surfaces are smeared with chalk. The stripes are drawn boldly, they should be 2-4 cm wide. First of all, the following areas are treated for house bugs:

• The entire room around the perimeter, the surface of the floor and baseboard, bottom part walls If the baseboards are damaged, then all cracks are processed additionally. By the way, it is precisely for such hard-to-reach or narrow areas that you can use aqueous solution chalk, picking it up with a brush for drawing. Dissolve the chalk in a small amount of water to obtain a slurry; it should be quite concentrated.
• The back surface of carpets or carpeting.
• The back of the furniture special attention is given to its lower part.
• Bed frame, if possible the lower part of the mattress or sofa cushions.
• The back surface of the paintings.
• If there is old wallpaper that is peeling off on the walls, the places where the walls are “exposed” are where the wallpaper is coming off (bedbugs and their larvae like to hide there).

The main part of the insects should disappear literally 2-3 days after treatment. Even if all individuals do not disappear immediately, this will happen within a week or two.

Igor Alekseevich, Tver

After 4-6 weeks, traces of the drug on visible and large surfaces are washed off with a soap-soda solution.

Pencil Mashenka and protecting the apartment from bedbugs

It is convenient to work with chalk and to prevent the appearance of bedbugs in the apartment.

Prevention is carried out in cases where bed bugs have already appeared in the premises before, or if it became known that one of the neighbors had them. Mashenka is perfect for such cases, since the room can be used immediately after it has been treated.

The algorithm for preventive treatment is almost the same as for exterminating insects. The only difference is that you don’t need to coat the treated areas so thickly; a strip 1 cm wide is enough.

In order to prevent bedbugs from entering the apartment from neighbors, the areas under and around the windows, as well as the frame and threshold should be treated front door. If there is a vestibule near the apartment, it is advisable to carry out preventive treatment there as well.

After the insecticide expires (4-6 weeks), it will also need to be washed off with a soap-soda solution.

Chalk Mashenka allows you to do it with little effort and without serious financial costs. The price of one pencil today is 6-10 rubles, and to process an apartment you will need about 3-4 pencils. Therefore, if it is very expensive to call a pest control team, but you need a really working method, you can use Mashenka chalk.

– all these harmful insects spoil a person’s usual way of life, causing a lot of trouble and even health problems with their presence. There are also pests scurrying around everywhere. The tiny size of insects allows them to penetrate into the narrowest and most inaccessible places, making it very difficult to get rid of them. After all, one of the main features of the Prussian body is the ability to survive even in the most unfavorable conditions. Among the mass of pesticides intended to combat Prussians, cockroach chalk Mashenka has been very popular for quite a long time.

Properties

The Chinese pencil was the first chalk against cockroaches, which appeared on the shelves back in the days of the USSR. Later, Russian manufacturers began to produce equally effective analogues.

Mashenka's cockroach repellent is made in the form of a white-gray chalk pencil. active substance it may contain chloropyphos or a combination of zetacypermethrin and deltamethrin. The basis of the pesticide is a cementing substance that has a negative effect on pests. Getting into digestive tract insect, the toxic composition blocks the work of vital important systems body, causing paralysis. The cement, reacting with gastric juice, hardens, which also dooms the Prussian to death.

Note!

The poison enters the insect's body through intestinal contact when it crosses the chalk strip, which is applied with an insecticidal pencil Mashenka. The more cockroaches touch this product, the better the result will be.

Cockroach chalk Mashenka is in great demand among the population, as it has a number of advantages:

• effectiveness - the result of the drug becomes noticeable after just a few hours;

• The insecticide loses its properties when exposed to direct sunlight and high temperature air.
• The product will not have an effective result if there is an excessive accumulation of cockroaches. Insecticidal sticks are only effective against small numbers of insects.

One package contains 20 g of product, which is enough to treat a room of 20 square meters. m.

Application methods

Before using the Mashenka anti-cockroach pencil, you must carefully read the manufacturer’s recommendations specified in the instructions.

1. To achieve maximum effect The product is applied around the perimeter of the room in a solid line, the width of which should be at least 1 cm. The speed of action of the product depends on the amount of poison that gets on the Prussian paws. The result of high-quality processing can be observed after an hour. Be sure to use rubber gloves for this.
   The main ones that need fine processing are: skirting boards, doorways, ventilation holes, window sills, water supply joints and sewer pipes, the back side of furniture, paintings and carpets, as well as various crevices and cracks in the apartment. The product is applied in remote places, trying to prevent accidental contact of family members with the toxic substance.
2. Cockroach chalk can also be crushed to a powdery state and used in this form for treatment hard to reach places. However, the use of this method is unsafe for humans, since toxic particles can enter the body on the mucous membranes oral cavity or into the respiratory organs. The consequence of such actions can be severe poisoning. Therefore, there is a need for the mandatory use of a respirator, safety glasses and rubber gloves.
3. Chalk is also diluted in water (1 package per 5 liters), and the resulting solution is used to treat the habitats of the Prussians. For this purpose, use a brush. You can also treat the room using a spray bottle.

Precautions

Like any other product, when using Mashenka chalk, you must follow the following rules:

1. Using crayons against cockroaches, eating, drinking or smoking is contraindicated during the pest control period. Violation of the manufacturer's recommendations is fraught with negative consequences. Ingestion of poison may be accompanied by abdominal pain, convulsions, insomnia and weakness. There may even be problems with vision.
2. At the end of the treatment, wash the face and hands thoroughly with soap and water.
3. If the product gets on the skin, wipe it with an alcohol solution and then rinse with water. If a toxic substance gets into your eyes, it must be washed off with plenty of running water.
4. If the insecticidal composition gets inside the body, then it is necessary to urgently consult a doctor. Before the ambulance arrives, you should drink a 2% soda solution, then induce vomiting, thereby clearing the stomach of poison.

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 ingredient

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. Affects nervous system in case of 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 tiny particles of water, active ingredients 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.

I remember from childhood that we always have behind the refrigerator, around the sink and trash can, around kitchen furniture, the toilet had these dashes and stripes. 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.

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;
• by inhalation of particles insecticide Animals may be poisoned.

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 you be sure that man and means have won ancient creatures on the ground.

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.

Chalks are among the cheapest, but quite effective means for fighting cockroaches. Chalk "Mashenka" is a long-recommended remedy; it belongs to safe means, which can be used in homes where animals and small children live.

Unlike the last century, the insecticide market has huge selection various drugs that are becoming more perfect every year. become not only more effective, but also safer for humans.

Composition of chalk

Mashenka chalk is produced in Russia, and the necessary toxicity tests were carried out before mass production and the appearance of the product on the market.

The composition of the chalk includes:

• Gypsum;
• Deltamethrin;
• Zeta-cypermethrin.

Almost 95% of chalk consists of gypsum and chalk and only 5% of active substances. Deltamethrin and zeta-cypermethrin are used to kill various insects. Gypsum serves as a base so that the drug can be applied to various surfaces.

Chalk “Mashenka” is sold in plastic packaging blue. Inside there is a small gray pencil weighing 20 grams. The packaging contains instructions for use and precautions; be sure to read them before use.

How does chalk work on cockroaches?

The pencil works when the insect walks along the chalk path. Once on the insect's paws, it gradually penetrates the body and begins to affect the nervous system. The components that make up the chalk paralyze the insect and it dies.

The anti-cockroach pencil does not work immediately, but after a certain time. The pencil will begin to produce results within a week, and you will notice half-dead crawling cockroaches. After 2-4 weeks, the pencil will completely destroy the cockroaches.

Instructions for use

The Mashenka chalk is easy to use; you just need to draw a line where insects are often found. Before applying chalk, you should inspect the apartment and determine the places where insects run. The main habitats of cockroaches are:

• Sink for washing dishes;
• Bin;
• Dushnik;
• Kitchen cabinets.

You should draw lines with a pencil along all baseboards and radiators so that there are no paths left for insects through which they can get around the chalk. How quickly cockroaches leave your home depends on your attentiveness. You should protect your apartment from the invasion of neighboring Prussians; to do this, just circle the air vent and the doorway with a pencil.

The duration of action of Mashenka decreases after 2 weeks, so you can repeat the procedure to achieve greater effectiveness.

To use the chalk, you need to open the package and start drawing lines. Additional measures safety is not required, after treating the room, wrap the chalk in a bag and place it out of the reach of children and wash your hands with soap.

Also, “Mashenka” for cockroaches can be used as a cleaning solution. It is necessary to crush the chalk and pour it into a five-liter bottle of water and then shake well. The resulting solution is used to wipe floors, baseboards and other places where insects may accumulate. Plus this method is a significant increase in the treated surface.

Pros and cons

The advantages of the drug include ease of use, low toxicity and cost. Compared to other drugs that require preliminary preparation rooms, as in the case of aerosol products, there is no need to ventilate the room after treatment. It should also be noted that there is no odor and safety for humans.

The disadvantages of this drug are the short duration of action, although the drug is effective for a month, its main activity decreases after the first week. If there are a large number of insects, destruction may take a long time. Manufacturers claim that Mashenka is a low-toxic drug, but you should make sure that the child does not start trying chalk, otherwise you may encounter unpleasant consequences.
