When detecting bugs in the room, any methods are used to destroy them. One of the most affordable, and at the same time popular, is the chalk “Masha”.
He has already proved to be very effective in the fight against cockroaches, ants and other domestic insects, and works well against blood-sucking parasites.
An important advantage of crayons is convenience and ease of use, and the absence of any unpleasant odor.
Chalk Masha from bedbugs
It is believed that the chalk "Masha" was developed by order of the Ministry of Defense to protect military supplies from insects. After the tool showed its effectiveness, it was decided to put it on the open market for civilian use.
Advantages and disadvantages
Like any tool, the small thing “Masha” has both advantages and disadvantages.
Among the advantages are:
- Ease of use - they can make lines in necessary places, spending a minimum of effort on this. Compared with aerosols and sprays, for which you need to pre-prepare the room, crayons can be applied immediately.
- Low price - This is one of the reasons for the high popularity of the tool. In hardware stores the price of a pencil is in the range of 20-30 rubles, which is available to people with any income level.
- Lack of smell and non-toxicity - thanks to this property, the use of tools can be made in the presence of people and pets. And since there are no toxic particles in the air, its toxicity is minimal.
At the same time, the chalk has several disadvantages:
- Small effective term - despite the fact that according to the instructions, the drug acts up to 6 weeks, it begins to lose its effectiveness after the 1st week. It is adversely affected by heat and sunlight.
- Low efficiency with large room contamination - if the colony of bed bugs in the apartment is large, the chalk will not be able to have a significant impact. It can be used as a co-agent with chemical treatment.
- Unwanted use in the presence of children - they may accidentally touch the lines drawn, with further ingress of the agent into their digestive system, which will lead to poisoning.

Forms of release
The drug "Masha" is available only in the form of a chalk bar of gray-white color weighing 20 grams. It is sold in an opaque blue packaging, on the back of which is located instructions for use.
The composition includes four substances.:
- Zeta-cypermethrin.
- Deltamethrin.
- A piece of chalk.
- Gypsum.
The first two components are poisons of contact action, and they destroy insects. However, at the same time, they can adversely affect humans and animals.
Impact mechanism
When a bedbug runs over the striated surface, poison is placed on its limbs, which is absorbed through the proboscis into the digestive system. After that, the substance begins to work.
Zeta cypermethrin and deltamethrin act on a similar principle interrupting the transmission of impulses in the nervous system. As a result, the functioning of all the muscles in the body of the parasite stops and it dies.
Compared with aerosols, which begin to act immediately when spraying and ingestion of insects, crayon works only after a certain time.
First, the bug should touch the vehicle, running along the drawn strip. As a result, the more parasites it crosses, the greater the effect can be achieved.
In addition, the particles of toxic substances on the paws fall into the nest, thereby affecting its other inhabitants.
ATTENTION! The death of insects begins from 4-5 days after contact, and reaches its peak in 2-4 weeks. At the same time, it is necessary to update the “barrier” lines every week.
Instructions for use
There are three ways to use the “Masha” chalk.:
- Draw a line across the routes of the parasites.
- Grinding fine and placing the resulting powder over the entire surface.
The advantage of this approach is that toxic substances will be applied in a thick layer over a large area. Its disadvantages are that when spilling it, it is necessary to close the mouth and nose from accidental inhalation, and the powder can be blown off or raised into the air by a stream of air. This works best when falling asleep in the cavity inside the furniture.
- Preparation of the solution - the ground composition can be dissolved in a certain amount of water, and the resulting mixture is sprayed on the treated surfaces.
The effectiveness of the effects of substances in each of the three cases is about the same, so you need to choose based on ease of use.
