What are bed bug chalks? How do they act on insects? How to work with them correctly? Precautionary measures. The assortment on the domestic market includes Mashenka, Tornado and others. Which chalk should you choose? If bedbugs appear in your home, you need to act immediately. Instantly spreading throughout the apartment, insects interfere with sleep, feed on blood, become a source of disease, and emit a characteristic odor. There are many products on sale that kill unfortunate parasites, among which are crayons.
Types of crayons against bedbugs
Chalk against bed bugs and other harmful insects in the house became popular in the Soviet Union. In appearance it resembles a piece of ordinary school chalk. Despite the fact that bed bug chalks have been used for a very long time, reviews of the insecticide are still good these days. There are wax and chalky poisonous crayons to combat bloodsuckers. In the first case, in addition to the chemical substance, the product contains paraffin and wax, and in the second, chalk or gypsum is added. These are binding elements due to which toxic components are retained on surfaces.
Components of Mashenka pencil
Chalk Mashenka is a product that is used to kill insects and prevent their appearance. The product has low toxicity and does not have a specific odor. In appearance, the drug is similar to an ordinary block of chalk. It contains active and auxiliary substances:
- Zeta-cypermethrin – 0.1%, a pyrethroid compound used to control harmful insects. It has a neuroparalytic effect on bedbugs. Not addictive.
- Deltamethrin – 0.05%, highly effective insecticide. Its action is designed for sucking and gnawing insects. When bedbugs enter the body through contact or intestinal routes, their coordination is disrupted. Causes paralysis and death. The toxic compound enhances the effect of zeta-cypermethrin.
- Chalk and gypsum are auxiliary components that allow you to apply the active substance to the surface to be treated.
The pencil is packaged in a plastic film bag. The weight of the chalk is 20 g. It can be stored in a wide temperature range from -30 to +400 C.
Composition of chalk
The pyrethroid group of pesticides makes up the main content of chalks against bed bugs. These are toxic substances for bloodsuckers and more or less harmless to humans. These include cypermethrin, fipronil, deltamethrin, which have a contact effect on insects. Cyprometrin is enhanced by the influence of other components and in tandem they effectively fight bedbugs. Cypermethrin has a destructive effect on the nervous system of the bug - disruptions occur in the parasite's nerve impulses, which leads to paralysis of the insect and its death. The larvae also do not survive under the influence of the chemical.
What are the advantages and disadvantages?
Advantages of crayons against bedbugs:
- low cost along with a visible effect,
- no pungent odor,
- ease of use,
- long-term effect on bedbugs,
- harmless to people and pets.
Flaws:
- suitable for treatment in case of minor infestation of the premises with bedbugs,
- prolonged onset of a positive result,
- the ability of insects to adapt to the action of an insecticide.
If bloodsuckers have largely attacked your home, then crayons are powerless here. You will have to resort to more powerful means of disinsection of the premises.
conclusions
It is advisable to use Mashenka chalk against bedbugs when the insect population in the apartment is insignificant. The pencil can be used quite successfully only in the early stages of infection and as a preventive measure against bloodsuckers. In heavily infested rooms it is no longer possible to do without powerful insecticides.

How to use the product correctly?
Crayons against bedbugs are used in different ways. It all depends on how infested the house is with parasites. If there are a lot of nests, then the best way would be to use chalk in a complex manner using all the methods listed below at the same time.
Grated chalk is dissolved in water, placed in a spray bottle or flower sprayer, and the habitats of bloodsuckers are generously treated. It is better not to water fabric surfaces and wallpaper with the solution, so as not to leave stains, and all other objects from which liquids can be easily washed off should be thoroughly sprayed. Carpet products are also sprayed with a solution, and then washed with powder and dried in the sun. You can prepare a viscous mixture of grated chalk and water, and use it to fill the cracks in floors, walls, and baseboards.
Rubbed to a powdery state, chalk is used to treat cracks, closed spaces and objects that do not tolerate moisture. These include: various horizontal surfaces, books, magazines, equipment. After the bedbugs die, the powder is removed using a powerful vacuum cleaner.
Using crayons, draw solid lines literally everywhere where bedbugs live and their possible escape routes. Approaches to beds, sofas, wardrobes and these pieces of furniture themselves must be well treated, as well as places from where bedbugs can enter the apartment. Particular attention should be paid to wooden surfaces. Bed bugs love them very much.
Preparatory stage of processing
Before treating your apartment with chalk against bedbugs, you need to perform several mandatory measures:
- do wet cleaning, thoroughly vacuuming all rooms to get rid of bedbug eggs as much as possible;
- free walls and baseboards from furniture and equipment;
- empty the house of all its inhabitants for a few days;
- isolate food and utensils;
- wash clothes, bedding, all household textiles in hot water and take them outside to air;
- treat mattresses with hot steam.
Procedure
Wear gloves when drawing barrier stripes with chalk. If you decide to work with a spray bottle or dry powder made from chalk, you should also wear a respirator.
The following are subject to insecticide treatment:
- the entire perimeter of the rooms along the baseboard;
- space on the floors under furniture and carpets;
- furniture on all sides and inside;
- shelves with books;
- places where the wallpaper is coming off the walls;
- objects located on the walls, from the front and back sides;
- cracks and secluded places in the house;
- windows, window sills, radiators, door jambs;
- ventilation vents.
After such a thorough treatment of the bedbug-infested apartment, you need to leave it for a day. When you return, you should wash objects and surfaces with which you constantly come into contact with soap and water. Everything that does not need to be touched should remain as is – treated with chalk for another 10 days. The residual effect of the chalk chemicals on insects will still remain. After 4-6 weeks, general cleaning with a soap and soda solution will be required.
After the specified period, the bedbug eggs present at the time of the first chalk treatment will hatch into larvae. All of the above will need to be re-coated with insecticide. In a few days, the bedbug population will completely die.
Features of the drug
The specificity of chalk is that it does not instantly kill bedbugs. After its use in the apartment, it is in the path of movement of insects. When the bloodsucker comes into contact with the substance of the chalk, it begins to eat into its integument, gradually poisoning the individual. The essence of the action of the chalk is the viral spread of the chemical among the bedbugs in contact with each other.
One chalk is enough to process 20-30 square meters of space. Lines should be drawn up to 4 cm wide.
Do crayons help against bedbugs? Judge for yourself - in the first week after treating a house with an insecticide, most of the bloodsuckers die. Then, thanks to a chain reaction of infecting each other, the remaining population of insects, along with their larvae, die in about 2 weeks.
For cleanliness of housing
A large number of jokes have already been made on the topic of cockroach crayons, but the fact remains a fact. Among the variety of gels and sprays against insects, the least dangerous and at the same time the most effective is the “Mashenka” chalk against cockroaches. Reviews emphasize that with the help of a simple drawing technique you can get rid of annoying mustachioed creatures.
How does this product work? A pencil or chalk exerts its effect due to the content of contact-type toxic substances. As insects crawl across the line, they catch small particles on their paws. This is how the insecticide begins to act. The insect stops feeding and soon dies.

Minuses
Judging by the reviews, “silver chalk” copes well with any pests that encroach on your home. However, it is not suitable for everyone and not in all cases:
- The product has virtually no effect on egg laying. There is a chance that the poisoned individual will return to the nest, and as a result the young individuals will die, but it is not too great. But the eggs themselves do not move.
- The chalk is very resistant to temperature, moisture and weathering. It does not lose its properties for a long time and therefore is not suitable for rooms where children live.
- A pencil will not work immediately and quickly, especially if you limit yourself to only applying chalk strokes. Of course, this will stop the reproduction of the individual and the spread of the insect population, but more effort will be required to completely exterminate them.
Considering these features, you can yourself assess the extent of damage to your home by insects and choose methods of control. If there is not enough time, then call a specialized team to carry out the sanitary procedure. processing. The same advice can be given if there is a large colony of insects in the house. Destroying them with chalk will take a very long time.
How to choose correctly?
Before you buy bed bug chalk, read what is written on the package. They must have a contact action. This is what is written on it. If it states that the insecticide has “intestinal” properties, then do not count on the desired effect from the drug. Bedbugs do not eat the contents of the chalk - they feed exclusively on blood.
The market today is overflowing with a wide range of crayons made in Russia and abroad. Before buying any chalk, be sure to read everything that is written on its packaging: who the manufacturer is, whether there is a certificate for the sale of chemicals, expiration date, precautions, composition. It is not recommended to buy crayons with a label in a foreign language. They are presented as analogues of domestic manufacturers.
