Disinsection (from the French dés-, meaning destruction, removal from Latin insectum — an insect) — one of types of disinfecting representing extermination of the insects capable to have inoculable infections, by means of special chemical means, by influence of hot water about the ferry or by means of biological means.

Disinsection is also understood as the procedure of extermination of any insects whose neighbourhood with the person is considered undesirable: flies, mosquitoes, cockroaches, ants, bed bugs, etc.

Preventive and focal disinsection

Preventive disinsection provides a complex of the procedures aimed at creation of adverse conditions for emergence, development and reproduction on an object of insects and ticks. For medical institutions, inhabited objects and hotels it, as a rule, consists in systematic washing and change of bed linen, frequent cleaning of rooms, cleaning of sewer pipes and planned cleaning of the surrounding territory.

Focal disinsection is carried out in places of outbreak of acute infectious diseases which carriers are arthropods. It consists in full destruction of carriers of infectious and inoculable diseases at various stages of their development. Depending on object infection degree with insects, apply physical, mechanical, chemical, biological means and also intestinal insecticides and fumigants to focal disinsection.

Types of disinsection

Medical disinsection is carried out in hospitals, medical clinics, policlinics, maternity hospitals, lunatic asylums, sanatoria and other medical institutions. Its purpose is directed to achievement of full sanitation indoors and in the surrounding territory of an object. For an exception of development of clothes louses, bugs, fleas, cockroaches of a moth and pincers systematic adoption of water procedures at patients, washing of clothes and bed linen, frequent cleaning of rooms, including chlorination has to be carried out. In order to avoid appearance of hygrophilous insects in a medical object, sewer, water and heating systems have to conform to all technical requirements.

Veterinary disinsection consists in creation of favorable and safe conditions for functioning of veterinary clinics, homeless animals shelters and similar institutions. As many animals become unintentional subjects to parasitizing of ticks and louses, there is a probability that these institutions can be subjected to infection with arthropods. In this regard in the centers of treatment of pets and homeless animals shelters the systematic complex of preventive disinsection actions is carried out.

Agricultural disinsection is a complex of procedures for destruction of arthropods which interfere with normal development of grain, leguminous, commercial and other crops that also leads to an economic loss. For implementation of procedures for agricultural disinsection means with the chemical composition (poisons, pesticides, insecticides) which are applied on a surface of plants by means of dispersion from aviation equipment or irrigating systems are used. Scot in the infected areas can be bathed in the pools which are specially equipped in the earth where fill in effective medicines — in the tropical countries it is daily practice.

Disinsection methods

Mechanical means, as a rule, ineffective way of destruction of arthropods, but effective remedy of protection against their stings. It provides use of mosquito grids at windows and around beds, and protective suits. Electric flycatchers, an adhesive tape and paper are applied to extermination of insects.

Physical means of disinsection provide use of the special equipment by means of which dispersion of cold fog, hot fog and also disinsection is carried out by heat. Generators of fogs and heating furnaces are classified depending on the possible area of processing and are divided into stationary and mobile. Besides these more modern ways of physical disinsection, in the centers of spread of itch and a pediculosis boiling of bed linen, clothes and footwear is carried out.
The biological way is often applied to destruction of larvae of flies and mosquitoes. Microbiological insecticides which are disputes of entomopathogenic microorganisms and toxins are for this purpose used. The most often biological method of disinsection is carried out in small reservoirs, cellars and warehouse.

The chemical way means use of special medicines which for each type of arthropods differ in the chemical composition. Apply to extermination of insects insecticides, ticks – acaricides, larvae – larvitsida, eggs of insects – an ovitsida. On a way of impact on wreckers these means also differ.

Impact on insects

For destruction of arthropods of a certain type a certain way of disinsection for achievement of maximum efficiency specially is selected. So, intestinal insecticides often are applied to destruction of red house ants, cockroaches, flies and other organisms with the gnawing or lizhushche-sucking oral device.

Use of fumigants is effective for the majority of insects as affects airways. Nevertheless, dispersion of fumigatsionny fog is possible not on all objects as this procedure demands the maximum tightness of the room that the gaseous substance emitted from the fog generator completely filled all space. But contact poisons which influence representatives of arthropods directly through contact with external covers of their body are most often applied.

Yours faithfully service of disinsection of Dis-man.
