There are many methods to kill rats, which can be generally divided into physical killing, chemical killing, biological killing and ecological killing.
1. Environmental deratization: Rats need water, food and hidden habitat to survive and reproduce. Therefore, creating an environment that is not suitable for its survival can greatly reduce the number of rats in a place and easily consolidate the results of rodent control. Therefore, first of all, we should do a good job in environmental sanitation, remove weeds around the house and articles piled at random, often clean indoor and outdoor sanitation, tidy up all kinds of utensils and sundries, and regularly check suitcases, wardrobes, books, shoes and hats to prevent rats from nesting.
Cut off the food of rats: the food of rats includes not only human food, but also feed, garbage, leftovers from food industry, feces and so on. These things should be stored in a covered, seamless container, so that rats can't get food and passively eat poison bait, thus achieving the purpose of killing rats.
2. Physical deratization: also known as instrument deratization, it takes a long time and has many application methods. It not only includes various special mousetraps such as mousetraps and cages, but also includes pressing, clamping, closing, clamping, turning, pouring, digging, sticking and shooting. Physical rodent control also pays attention to certain technology. For example, the rat cage (clip) should be placed in the rat hole, with a certain distance from the rat hole, and sometimes some camouflage can be done to improve the killing rate; The bait on the mouse cage should be fresh, which should be the food that mice like to eat. Generally, it is difficult for mice to get into the cage on the first night because of "new reaction", and the rate of getting into the cage will increase after two or three days.
3. Chemical deratization: also known as drug deratization, is the most widely used and effective method of deratization. Drug deratization can be divided into intestinal poison deratization and fumigation deratization. As an intestinal rodenticide, organic compounds are the main ones, followed by inorganic compounds, wild plants and their extracts. Gastrointestinal rodenticide requires good palatability to mice, will not refuse to eat, and has appropriate toxicity. It is mainly used to make all kinds of poison bait with good effect, simple use and large dosage. Followed by poisonous water, poisonous powder, poisonous glue, poisonous foam and so on. Fumigation and deratization, such as aluminum phosphide and chloropicrin, can be used for fumigation and deratization of warehouses and ships.
4. Biological deratization method: It includes two aspects: First, using natural enemies to kill rats. There are many natural enemies of rats, mainly weasels, wild cats, domestic cats, foxes and other carnivores. Birds of prey such as eagles and owls. And snakes. Therefore, protecting the natural enemies of these rodents is conducive to reducing the harm of rodents.
5. Ecological rodent control: that is, by improving the environment, including rodent control buildings, cutting off rodent food, transforming farmland, improving indoor and outdoor environmental sanitation, and removing hidden places for rodents, that is, controlling, transforming and destroying the living environment and conditions conducive to the survival of rodents, rodents can not survive and reproduce in those places. Ecological rodent control is an important part of comprehensive rodent control.
Rat prevention method
Doing rodent control well is the key to eliminate rodent damage, especially in rural areas.
Trench network: add barbed wire at the entrance and exit of the sewer, and the mesh diameter shall not be greater than 1 cm to prevent rats in the sewer from climbing up and down the pipeline. Open ditches in the operation room of catering industry shall be covered with nets or other articles, and shall not be exposed.
Rat-proof door: you can nail an iron plate 30-50 cm high in the lower half of the door to prevent rats from biting the door panel, or add an iron gate 60 cm high to keep rats out. It is best to prevent rats in the whole house.
Narrow the gap: repair the gap between the door and the ground, the door and the door, the window and the windowsill, so that the gap is not more than 0.6 cm, to prevent house mice from entering.
Hardened ground: repair the damaged and unhardened ground in time, or harden the road surface to prevent rats from stealing holes and nesting.
What about the dead mice?
Dead rats can be disinfected by spraying 0.05% peracetic acid or 1000mg/L solution containing available chlorine. The dosage should ensure that the surface of the mouse corpse is completely wet, then sealed with plastic bags and sent to the sanitation department for harmless treatment. After disposing of the dead rats, disinfect the places that may be contaminated by rats with disinfectant, and wash your hands for disinfection.
