Disinsection is the destruction of arthropods (fleas, lice, flies, bedbugs, ticks, moths, etc.) that are harmful to humans, animals, food, and agricultural matter. products, furnishings, etc. Disinsection measures are divided into medical, veterinary and agricultural.
Medical activities include the extermination of insects and ticks, which are carriers or reservoir of certain infections, as well as interfere with the work and rest of people. Disinsection medical measures are divided into preventive, or preventive, and destructive.
To preventive measures include the observance of the rules of personal hygiene, as well as sanitary and sanitary-technical rules aimed at creating conditions that prevent the existence and reproduction of insects. For example, regular body wash and change of body and bed linen are the main measures to prevent lice.
Systematic cleaning of residential premises, timely sealing of cracks in the walls, floors, along the input of heating pipes, etc., as well as the maintenance of cleanliness in the kitchen (shelter of food, removal of food garbage) prevent the reproduction of bedbugs, cockroaches and red house ants. Keeping the public clean of a toilet , the territory of yards, premises for livestock, as well as the systematic removal of manure and debris create unfavorable conditions for the development of flies.Go
Extermination measures are aimed at the destruction of arthropods at all stages of their development by mechanical, physical, biological and chemical methods.
The mechanical method of disinsection is based on the use of various mechanical methods and means of combating insects: knocking out, shaking off, removing dust and debris using brushes, vacuum cleaners, etc .; in the fight against flying insects (flies, mosquitoes , mosquitoes) check the windows and doors; sticky paper and various flycatchers are used to catch flies; apply traps for cockroaches.
The physical method of disinsection has not lost its value. So, for the destruction of lice using hot-air chambers, hot iron. Against bedbugs and cockroaches use boiling water, hot air, as well as fire (blowtorch).
The biological method of pest control is not significant. The only exception is the use of the mosquito fish (see) to kill the larvae of anopheles mosquitoes.
The chemical method of disinsection uses various poisons. Depending on the ways and means of penetration of insects into the organism of the insects, they are divided into contact ones, acting through the outer integument when in contact with them; intestinal, ingested with food, and fumigants, penetrating in the form of gas or vapor through the respiratory tract.
