Deratization is extermination of rodents (see), harmful to humans in epidemiological and economic terms.
Deratization in the cities and villages of Russia conduct departments and offices of preventive disinfection of sanitary-epidemiological stations.
Deratization includes preventive and curative actions. In settlements prevention consists of sanitary and construction-technical measures, and in the field, from farming. Curative composed of chemical, mechanical and biological methods.
Sanitary and construction and technical measures ensure the cleanliness of the premises and adjacent to the buildings and land plots. For this, spend cleaning of premises and territories, rubbish and food waste is collected in iron boxes, bottles or buckets with lids. Food store out of the reach of rodents container.
On the routes of movement of rodents create various obstacles. Doors in basement must always be fitted and closed tightly, cracks in floors and walls, places of input of cables, water supply and gas pipes are sealed with cement or iron, ventilation holes are protected by a metal grid with cells of 0.5, see
At the present time are used drugs, rodent repellent (repellents) in order to protect the houses of the wires in the ground and so on, For this is recommended zinc salt diethyldithiocarbaminate acid, shale oil, and other albital
Agrotechnical measures are aimed at deterioration of inhabitancy conditions of rodents, depriving them of their shelters and food in the field conditions. To do this, hold the spring treatment of winter tillage, vapours and fields under spring, systematically destroy weeds; harvesting and threshing produce in time, destroy unused balances of straw and vines.
Curative actions. The chemical method is used poisoned baits and sometimes gases. To poisoned baits best poisons are: Krysin, phosphide zinc, warfarin, Ratingen and peracetate. For manufacturing lures often use bread crumbs from grey wheat bread (for rats and mice), grain and various cereals (mice), grain and vegetables (for field rodents). In dry premises apply dusting water krusedol, warfarin, rathindran, in places with high humidity - paraffin briquettes (poisoned bait, paraffin). Along with the use of poisoned baits spend dusting Nord and trails rodents with warfarin and atindana.
For simultaneous destruction of rodents and their fleas apply poisons systemic action (peracetate) or combined bait (zinc phosphide with DDT).
Gases used on ships, in grain warehouses for handling of railway cars and burrows of rodents in the field. Using cyan, chloropicrin, sulfur dioxide and methyl bromide.
When mechanical methods for the destruction of rodents set along the walls and close to the Nord different fishing gears (snares and traps).
Biological methods include the use of bacterial cultures from a group of Salmonella and natural enemies of rodent predators and birds). Currently have increasingly used a combination bait, consisting of a bacterial culture and cresida or zoomarine (Banjarmasin).
In urban areas the most effective continuous systematic deratization, which is conducted during the year, the planned processing of all municipal buildings. In small communities Pets systematic process only the most inhabited by rodents objects and epidemic indications conducted a continuous deratization. Cm. also Deratization means.
