The destruction of rodents is called deratiration. Deratization It is carried out by several methods: mechanical, chemical, biological and biochemical.
Chemical preparations are used when preparing bait. To do this, they are mixed into food rodents. Zinc phosphide is a gray powder with a pronounced phosphorus smell. It consists of 26% phosphorus and 74% zinc. This poison is poorly dissolved in water, so it is dissolved in an acidic or alkaline medium. For mice, the deadly dose is from 150 to 200 mg / kg, for rats from 75 to 150 mg / kg, 3% of zinc phosphide are mixed to prepare the bait. This drug in wet bait decomposes. It has a nervous effect on the body. The death of poisoned rodents passes throughout the day. Fluorinaste sodium - gray powder. Also poorly dissolved in water. For mice, the consumption of the drug is calculated taking into account the following dose - 12 mg / kg, and for rats - 1 mg / kg. The death of animals occurs a few hours after receiving the drug. In the manufacture of bait, it is added 1-3% of the meal volume.
Monoforin - consists of gray-pink crystals. Mortal dose for rats and 15mg / kg mice. When using this drug, it is necessary to take into account the fact that it is very sensitive and pets - cats and dogs. Mortal dose for cats 2.2 mg / kg, and for dogs - 1.25 mg / kg. In the use of cumulative action drugs, they must be launched several times within a few days. They are aimed at slowing the process of blood intake and damage to blood vessels. The death of animals occurs mainly through blood hemorrhage into the brain. The composition of these drugs includes poison in different proportions and various fillers.
Zoocumarine is based on the action of the poison of oxycumarine, which contains 1%. The drug has a gray color. Mortal dose for mice and rats 0.25 mg on a disposable reception. Animals are dying within a few days. An antidote of this drug is vitamin K. Difenacin is also used as zoocumarine.
Fantolacin - a yellow powder, which contains 0.25% of the ADV. The most sensitive to the preparation of the rat. The deadly dose for them is 0.75mg. In the manufacture of bait add 2 to 8% of the drug. Upon spraying, 5g.penolacin is used as a foam from 0.5% of the ADV and is sold in spraying spray 200 ml. For deratiration, foam clog holes. The balloon is designed to climb two - three holes (depending on size) or making bait up to 20kg. It is also used within a few days before the complete destruction of rodents.
