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 make it easy to consolidate the results of rodent control. Therefore, we must first do a good job in environmental sanitation, remove weeds around the house, and randomly pile up items, 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 rats' food: Rats' food includes not only human food, but also feed, garbage, leftovers from food industry, feces, etc. These things should be stored in a covered and seamless container, so that rats can passively eat the poison bait without food, so as to achieve the purpose of killing rats.

2. Physical deratization method: also known as instrument deratization method, it has been used for a long time and has many application methods. It not only includes all kinds of special mousetraps, such as mousetraps and cages, but also includes pressing, clamping, closing, clamping, turning, irrigation, digging, sticking and shooting. Physical rodent control also pays attention to certain science and technology. For example, the rat cage (clip) should be placed at the rat hole, with a certain distance from the rat hole, and sometimes some camouflage can improve the killing rate; The bait on the rat cage should be fresh and should be the food that rats like to eat. Generally, it is difficult for rats to get into cages on the first night because of "new reaction", and the rate of getting into cages will increase after two or three days.

3. Chemical deratization: also known as drug deratization, it is the most widely used and effective deratization method. 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 rats, will not refuse to eat, and has appropriate toxicity. It is mainly used to make various poison baits with good effect, simple usage 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 in warehouses and ships.

4. Biological rodent control method: It includes two aspects: First, using natural enemies to kill rodents. There are many natural enemies of rodents, mainly carnivorous animals such as Yellow weasel, wild cats, domestic cats, foxes, etc., birds of prey such as eagles and owls, and snakes. Therefore, protecting these natural enemies of rodents is beneficial to reduce rodent damage.

5. Ecological rodent control: that is, by improving the environment, including rodent-proof 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, so that rodents can not survive and reproduce in those places. Ecological rodent control is an important part of comprehensive rodent control.
