Rat damage is a serious worldwide problem. Residents in every corner of the globe are threatened by rodents, because the number of domestic rodents on the planet is much larger than that of all the population. It is estimated that the number of rodents is three to four times that of the population.

The main rodent species in cities and towns in China are commonly called domestic rodents, including Rattus norvegicus, Rattus flavipectus and Mus musculus.

Rats can directly transmit pathogens to humans, or indirectly to humans through in vitro parasites, playing the role of vector and bacterium. The main rodent-borne diseases in China are plague, leptospirosis, epidemic hemorrhagic disease, typhus typhus, schistosomiasis, trichinosis and salmonellosis.

Domestic rats have the characteristics of short life span, strong fecundity and early sexual maturity, with an average life span of 6-7 months; female rats reproduce an average of 35 young rats per year; and the sexual maturity time of young rats is 70 days.

All three species of house mice are omnivorous, but their preferences depend on past experience and the type provided by the environment. Rattus norvegicus and Rattus flavipectus eat a wide range of food, such as various grains, meat, fruits, garbage, animal manure, as well as various insects, vegetables, weeds and grass seeds.

Rodenticides are divided into acute rodenticides and anticoagulant rodenticides. At present, acute rodenticides have a great impact on human and animal safety, and most of them are banned by the state because of the lack of specific antidotes. Anticoagulant rodenticides are the safest and most effective chronic rodenticides (vitamin K1 is a special antidote). Common anticoagulant rodenticides are rodenticides, rodenticides, diphacinone, Bromadiolone and anticoagulant rodenticides. After 4-10 days of bait administration, the remaining bait could not be removed, or the rodents in the area could be completely controlled by using bait box for a long time. Generally, the consumption reached a peak on the third to fourth days of bait administration, and then the rat corpse appeared, and the rodents in this area could be completely killed in 10-15 days.

There are many ways to kill rodents. Our company uses physical, chemical, biological and ecological methods to kill rodents, as follows:

1. Environmental rodent control: Rats need water, food and hidden habitat to survive and reproduce. Therefore, creating an unsuitable environment for its survival can greatly reduce the number of rats in a place and make the results of rodent control easy to consolidate. So my company first suggests doing a good job in environmental hygiene, clearing weeds around the house, randomly stacked goods, often cleaning indoor and outdoor hygiene, cleaning up all kinds of appliances and sundry things, checking suitcases, wardrobes, books, shoes and hats, etc. frequently, so as not to make rats nest; cutting off the food of rats: not only human food, but also feed, garbage, food industry. Scraps, feces and so on, these things should be stored in the covered and seamless container, so that rats can not get food and passively eat the poisonous bait put in, in order to achieve the purpose of killing rats.

2. Physical rodent control method: also known as instrument rodent control method, which has been used for a long time and has many ways of application. It includes not only all kinds of special rodent traps, such as rat traps and cages, but also pressure, clamping, turning, irrigation, digging, sticking and shooting. Physical rodent control also pays attention to certain science and technology, such as placing a cage (clip) at the mouth of the rat hole, should have a certain distance from the rat hole, sometimes with some camouflage, can improve the killing rate; the bait on the cage should be fresh, should be the favorite food for rats. Generally, rats are not easy to be caged on the first night because of the "new reactions", and the rate of caged mice will increase after two or three days.

3. Chemical rodenticide: also known as drug rodenticide, is the most widely used and effective method of rodenticide. Drug rodenticide can be divided into enterotoxic rodenticide and fumigation rodenticide. The intestinal rodenticides used as rodenticides are mainly organic compounds, followed by inorganic compounds, wild plants and their extracts. Gastrointestinal rodenticides require good palatability, no antifeedant and proper toxicity to rats. It is mainly used to make various poisonous baits with good effect, simple usage and large dosage. Secondly, poison water, poison powder, poison glue, poison foam, etc. Fumigation of rodents, such as aluminium phosphide and bitter chloride, can be used to fumigate rodents in warehouses and ships.

4. Biological rodent control methods include two aspects: one is the use of natural enemies to kill rats, many natural enemies of rodents, mainly small carnivorous animals such as weasels, wildcats, cats, foxes, birds of prey such as eagles, owls, and snakes. Therefore, our company suggests to protect these natural enemies of rodents in rodent control areas, which is beneficial to reduce rodent damage.

5. Ecological rodent control: that is, by improving the environment, including rodent-proof buildings, cutting off rat food, farmland transformation, doing a good job of indoor and outdoor environmental hygiene, clearing rodent shelters, etc., that is, controlling, transforming and destroying the living environment and conditions conducive to the survival of rodents, so that rodents can not survive and multiply in those places. Ecological rodent control is an important part of integrated rodent control.

II. Rodenticides

According to the speed of action of rodenticides in rats, they can be divided into acute and chronic groups.

1. Acute rodenticide, also known as acute single dose rodenticide, can kill rats if they eat enough lethal bait at a time. The advantages of these drugs are quick action and less food consumption, but they are unsafe to humans and animals, and easy to cause secondary poisoning. At the same time, before the death of rats in the process of rodenticide, they reflect more intensely and easily cause the alertness of other rats, so their efficacy is less than that of chronic rodenticide. These drugs include zinc phosphide, fluoroacetamide, tetramine, tetramethyl bromide, tetramethyl bromide, dibromobromide and so on. Fluoroacetamide, Tetramine and glycofluorine are highly toxic and have no specific antidote, which can easily cause human and animal poisoning. The state has explicitly banned them.

2. Chronic rodenticides, also known as slow-acting rodenticides, can be divided into the first and second generation of anticoagulant rodenticides. The first generation of anticoagulant rodenticides, such as dichlorvos sodium salt, carbendazim, ricketamine, chlordiphenicol, etc., need to be administered for several consecutive days in order to achieve the desired rodenticidal effect. The acute toxicity of the second generation of anticoagulant rodenticides is relatively strong. The mice can be killed twice or three times, and the mice resistant to the first generation of rodenticides can also be killed. These drugs include bromadiolone, bromadiolone, thiodilone, etc.

Dead rat treatment:

1. pack the dead rats in bags, dig ditches in open areas, burn them with gasoline and bury them.

2. Transport dead rats to open lawns, dig deep ditches of 50CM, disinfect them with lime powder and bury them.

3. The dead rats can be sprayed with 0.05% peracetic acid or 1000mg/L solution containing available chlorine, sealed with plastic bags, and sent to the sanitation department for harmless treatment.

After dealing with the dead rats, disinfect the places possibly contaminated by rats with disinfectant and wash hands.

IV. NOTES

1. In the process of rodent control, it is forbidden to use acute drugs, otherwise it will cause rat alertness, so as to refuse to take bait.

2. Rats have the habit of molars. They like to eat shelled bait. When they eat rice, they spit out the husk instead of eating the grain. Therefore, they often bite the telephone line and the net line. Mouse

3. The construction personnel can judge the rat track according to the scene and put the medicine into the necessary place where the rats will come and go.

4. Mus musculus has little food and is suspicious, so that it can not be completely exterminated by using bait alone. It must be supplemented by physical control methods such as rat cage and viscose mice glue.

5. The bait for rodent control must be fresh, the method for dosing should be standard, and the place should be accurate and concealed to ensure that the rats can eat, so as to control the rodent effectively.

6. To put rodent bait into operation, three rates should be achieved, that is, 100% coverage rate, 100% arrival rate and 100% retention rate. It is an effective method to put rodent bait in the same area at the same time and concentrate action at the same time.

7. Drug bait should be tested to have more rain in the south so as to avoid the rain of rodenticide as far as possible. (Wax bait can be put in places with long-term humidity, such as sand wells). Clean up the invalid old bait before dosing to keep the bait fresh and effective.

8. 10,000 people with animal poisoning can be detoxified with vitamin K1.
