Disinfectants are biologicals, mechanical devices, and chemicals used to kill rodents.
Biological means. These include bacterial cultures (from the Salmonella group), causing the death of rodents. Such deratization means are usually used in spring or autumn with a high number of rodents in limited areas. A bacterial culture is prepared and special laboratories are packed in 0.5–1 l containers. For the preparation of baits with bacterial preparations take 1 liter of culture and mix it with 1.8 kg of flour, or with 1 kg of crackers, or 3 kg of grain. The dough obtained from flour is cut into pieces (20-25 g for rats), which are then laid out on objects. Crackers and grain soaked in liquid culture for 1-2 hours. For the fight against rodents in the field, forest, on the backyard plot, grain bait is used, spreading it by 5 g per burrow. In stacks, ricks and omets the bait is laid out in special baiting boxes.
Bacterial drugs are practically not dangerous for humans and healthy animals.Go
Mechanical tools are used alone or in combination with bacterial or chemical means to kill rodents. Mechanical tools are also used to account for the number of rodents and determine the effectiveness of deratization works. These deratization means are divided into villating and killing. The first includes wire live traps on a wooden base, vertices, various traps (for mice and rats), etc. Versions and traps, unlike wire traps, automatically work for a long time; recharge after catching each rodent is not required. Killing devices include arc traps used to trap rats, gophers, gerbils, etc., spring traps, mounted on a plank. Traps set near exits from the holes or along the paths of rodents. As a bait, pieces of black bread moistened with vegetable oil, sausage, cheese, and vegetables are attached to the hook of the trap.
The technique of cooking baits.
The poison in the required concentration is thoroughly mixed with the food base (bread crumb, hard boiled porridge, flour or crushed crackers, etc.) and add 2-3% vegetable oil.
Grain bait (wheat, oats, corn) is soaked for 24 hours in a solution of one of the preparations, and then dried in air. Powdered poisons stick to the grain with thorough mixing of the latter with vegetable oil (2%).
Precautions . All chemical disinfectants should be stored in a specially designated dry cool room, under lock and key.
When preparing baits with powdered poisons and when pollinating rod holes and trophies, one should protect the nose and mouth with cotton-gauze dressings or respirators . The mixing of the food base with the preparations is carried out in a well-ventilated room or in a fume hood. Weighing the preparation and packaging the bait is carried out in rubber gloves . While working with poisons and poisoned baits, it is strictly forbidden to smoke or eat.
After work, wash hands with soap and water and rinse your mouth. During the gas treatment of the premises, gas is released from the cylinders, starting from the far rooms, gradually moving to the exit. Responsible for gassing ensures that all disinfectants leave the building.
