How to use cockroach dust: tips and tricks

Powerful insecticides in powder form are called dusts. Due to the high concentration of the active substance, they effectively kill synanthropic insects and other pests. Powders are affordable and easy to use. Dust from cockroaches remains active for 6-8 weeks. On sale you can find insecticidal powders of various brands, they are united by the unchanging ability to rid the premises of crawling insects.

The composition of dusts

In the fight against synanthropic insects, powder agents are often used. This is a universal method of getting rid of cockroaches, ants, bugs and other pests that interfere with human life. Modern dusts have nothing to do with DDT used in the 20th century. Dichlorodiphenyl trichloromethylmethane is an insecticide that has no analogues in terms of exposure to insects. Elderly people with nostalgia remember the powder, which helps from any misfortune.

Interesting. The insecticidal properties of DDT were discovered by the Swiss chemist Paul Muller. He noticed that the substance is a potent contact poison. For his discovery, the scientist received the Nobel Prize.
After research, DDT was banned for use, it turned out that its toxic effect extends not only to pests, but also to humans. Poisonous compounds accumulated in tissues, worsening the health of humans and animals.

Attention. Dust DDT is approved for use in mosquito control. It is used to prevent malaria.

In modern dusts there is no DDT, the name of the drugs is associated with the English word “dust” - fine powder. Finely ground mixtures consist of active substance and excipients. The insecticide content determines the activity of the drug, usually the concentration is 1-10%. The dust formula includes:

• cypermethrin;
• malathion;
• chlorpyrifos;
• malathion and other synthetic pyrethroids.

Chalk, talc, gypsum, kaolin are used as filler for cockroach dust from cockroaches. Additional substances should not coalesce and react with an insecticide. For ease of application, the powder particles should have a size of 15-25 microns. Small particles of dust are firmly attached to the body of arthropods while running on the treated surface.

The principle of action of insecticidal powder

Dust is a powder of white or grayish color, odorless. The effectiveness of its use and the features of exposure to insects depend on the active substance. The active components of powder preparations are divided into several groups:

Pyrethroids

Pyrethroid-based drugs are most prevalent. They have a nerve effect on cockroaches. Synthetic compounds are analogues of natural insecticides. Common compounds include:

1. Cypermethrin is a highly active contact-intestinal insecticide. Getting into the body of cockroaches paralyzes their nervous system. Funds based on it are allowed for pest control in residential, children's and medical institutions. They belong to the least harmful 4th class of danger. The residual effect is 1-1.5 months.
2. Permethrin - an insecticide that acts on the central and peripheral nervous system. Accumulating in the tissues causes arthropod paralysis.
3. Lambda-cygalotrin is an odorless white substance, stable in the light. It has a contact, intestinal and repelling effect. It affects the motor centers of insects, provides quick destruction, the death of pests occurs after 24 hours.

Organophosphorus Compounds (FOS)

Phosphorus-based insecticides have intestinal and systemic effects. They cause paralysis and insect death.

1. Chlorophos - the substance is toxic to arthropods, exhibits an acute intestinal effect against synanthropic insects. This is due to the increase in toxic properties in an alkaline environment.
2. Chlorpyrifos - the compound penetrates the body through the respiratory organs, stomach and integument of the body. The drug is resistant to the environment, has a paralyzing and acute intestinal effect. With uncontrolled use, it causes resistance of synanthropic insects.

Boric acid

One of the effective powders for cockroaches is boric acid. The substance is used independently and is part of the Clean House series of insecticides. White powder is intended for antiseptic processing, but for insects it is a deadly poison. The acid acts through the digestive system, so the insect must eat it.

The substance is mixed into food lures, the yolk of an egg, mashed potato can become the basis. Balls with poison are laid out in the habitats of pests - under the sink, in the bathroom. The composition is valid after a few days. Insects develop a violation of nervous activity, paralysis and death occurs. In places of movement, paths of boric acid are poured. The powder falls on the legs and limbs, and then transferred to food.

Attention. With frequent use of the drug, cockroaches develop resistance.

Borax has a similar effect, this substance can be used instead of boric acid.

Dust-causing dusts

Diatomaceous earth powder is crushed rock. Upon contact with the body of cockroaches, it causes damage to the chitinous cover. The liquid begins to evaporate quickly from the body. The process accelerates the absorption of water by diatomite themselves. As a result, insects die from dehydration.

Advantages and disadvantages of drugs

With proper processing of rooms with powders, most of the insects are etched in the first hours after processing, the rest die in a few days. The use of the preparative form of dust has several significant advantages:

• high toxicity to synanthropic insects;

• the ability to not change properties under the influence of high and low temperatures, sunlight;
• application prostate - powder can simply be poured in places of cockroach accumulation;
• dusts retain a poisonous effect for a long time;
• the product is odorless, safe for people;
• accessibility - drugs are sold in all hardware stores, their cost is significantly lower than that of aerosol products.

Among the shortcomings of the drugs, it is worth noting:

• lack of instant result;
• difficulty in cleaning;
• the need to put up with powder on the floor for a long time.

Furniture pieces move away from the walls to process the skirting around the perimeter. It is necessary to process all the cracks and openings in the walls, door frames, ventilation grilles and sewer inlets, risers. Particularly carefully scattered powder in the kitchen - the site of the largest accumulation of pests. A thin layer of insecticide is applied behind the refrigerator, stove, under the sink, behind the cabinets. Food storage locations are not processed. Evenly distribute dust will help brush. For hard-to-reach spots, you can prepare an aqueous solution and spray with a spray gun.
