How to deal with mice?

There are many methods of killing rats, which can be generally divided into physical killing rats, chemical killing rats, biological killing rats and ecological killing rats.

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.

3. Rodenticide

1. Rodenticide can be divided into acute and chronic types according to the speed of action after it enters mice.

acute rodenticide, also known as acute single-dose rodenticide, can kill rats by eating enough toxic bait at one time. These drugs have the advantages of quick action and low food consumption, but they are not safe for people and animals, and are easy to cause secondary poisoning. At the same time, they react violently before the death of rats in the process of deratization, which is easy to alert other rats, so their efficacy is not as good as that of chronic rodenticide. This kind of drugs include zinc phosphide, fluoroacetamide, tetramine, bromogeramine, dibromide and so on. Amine fluoroacetate, tetramine and glyphos are highly toxic and have no specific antidote, which can easily lead to human and livestock poisoning, and the country has explicitly banned them.

chronic rodenticides, also known as slow-acting rodenticides, can be divided into the first generation and the second generation anticoagulant rodenticides. The first generation of anticoagulant rodenticides, such as diphacinone sodium salt, rodenticide, rodenticide, and chlorpyrifos, must be administered for several days in order to achieve the ideal rodenticide effect. The acute toxicity of the second generation anticoagulant rodenticide is relatively strong. Rats can die after eating it twice or three times, and rats resistant to the first generation rodenticide can also be killed. These drugs include bromadiolone, Dalong, Butazhang, Thiadiolone and so on.

2. Why is chronic rodenticide better than acute rodenticide?

The advantages of chronic rodenticide are: the dosage is small, rats will not refuse to eat until they die, so the rodenticide effect is good, and the chances of livestock poisoning are few. Poisoned animals can also be rescued with a special antidote (vitamin K1). Chronic rodenticide conforms to the habit of mice to eat. Rats eat intermittently and stop eating. However, most kinds of chronic rodenticide are not very toxic once, and there is no uncomfortable feeling after eating it. It can be eaten for several days continuously, and the toxicity will be strong when it is accumulated, and the mouse will die. The effect of chronic rodenticide is slow. Most rats die after taking medicine for more than three days, and there are no severe symptoms before they die, so they are still taking poison bait when they die. Therefore, when a large number of rats die, almost all rats have eaten enough lethal dose of rodenticide, even if some rats stop eating or moving, they will inevitably die. There is no problem that a large number of dead rats scare away the survivors. Chronic rodent control can kill many kinds of rodents, and it is safe to use in a large area, with good rodent control effect and a large number of dead rats. It is the main weapon for rodent control at present. Chronic rodenticides mainly refer to anticoagulant rodenticides, such as bromadiolone and Dalong.

3. Precautions for purchasing and putting rodenticide

(1) Buy rodenticide from a department qualified to handle rodenticide.

(2) Understand the ingredients of rodenticide used and the safe detoxification methods.

(3) Put rodenticide out of the reach of children.

(4) In case of accidental ingestion, send it to the hospital immediately.

4. Safe use of rodenticide

According to the data, pesticides and rodenticides are the top two types of poisons that lead to poisoning in China, with pesticides accounting for 29.22% and rodenticides accounting for 28.62%. The dosage of pesticides in China is much more than that of rodenticide every year, so in proportion, acute and highly toxic rodenticide is the primary factor of poisoning death of ordinary people in China.

Before 195, acute rodenticide was the main method to kill rats, and tetramine and other commonly used drugs, which were highly toxic and had no antidote, and had long been banned. At present, chronic rat drugs, mainly anticoagulants, are usually used. After taking the drugs, rats have mild symptoms, which are not easy to arouse the vigilance of the same kind, and the concentration is low, which is safer for people and livestock. Antidotes are commonly used in clinic and are easy to be rescued after poisoning.

iv. rodent control methods

doing a good job of rodent control is the key to eliminating rodent pests, especially in rural areas.

gutter net: add barbed wire at the outlet and inlet of the sewer, and the mesh diameter should not be greater than 1cm to prevent rats in the sewer from getting up and down the pipeline. The open ditch in the operation room of catering industry should be covered with nets or other items, which should not be exposed.

Rat-proof door: iron sheets 3-5 cm high can be nailed to the lower half of the door in important places to prevent rats from gnawing at the door panel, or an iron gate 6 cm high can be added to keep rats out. It is best to prevent rats in the whole house.

Narrowing the gap: repair the gap between the door and the ground, between the door and the window, and between the window and the sill, so that the gap is not more than .6 cm to prevent the house mouse from entering.

hardened ground: repair the damaged and unhardened ground in time, or harden the road surface to prevent rats from stealing holes to make nests.

5. How to deal with dead rats?

The dead rats can be disinfected by spraying with .5% peracetic acid or 1mg/L solution containing available chlorine, and the dosage should ensure that the surface of rat carcasses is completely wet, then sealed with plastic bags and sent to the sanitation department for harmless treatment. After handling the dead rats, disinfect the places that may be contaminated by rats with disinfectant and wash your hands for disinfection.
