Let me introduce some ways to kill rats:
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 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.
Third, rodenticide.
1. Rodenticides can be divided into acute and chronic types according to the speed of action after entering mice.
Acute rodenticide, also known as acute single dose rodenticide, can kill rats by eating enough poison bait at one time. These drugs have the advantages of quick onset and less food intake, but they are not safe for people and animals and are easy to cause secondary poisoning. At the same time, in the process of killing rats, they react violently before the death of rats, which is easy to alert other rats, so their efficacy is not as good as that of chronic rodenticide. These drugs include zinc phosphide, fluoroacetamide, tetramine, bromogeramine, dibromonate and so on. Amine fluoroacetate, tetramine and glyphosate are highly toxic, and there is no specific antidote, which can easily lead to human and animal poisoning, which has been explicitly prohibited by the state.
Chronic rodenticides, also known as slow-acting rodenticides, can be divided into the first and second generation anticoagulant rodenticides. The first generation of anticoagulant rodenticides, such as diphacinone sodium salt, rodenticide, rodenticide, chlorpyrifos, etc., must be used continuously for several days to achieve the ideal rodenticide effect. The second generation anticoagulant rodenticide has strong acute toxicity. Rats can die after eating two or three times, and rats resistant to the first generation rodenticide can also be killed. These drugs include bromadiolone, Dalong, Butazinone and thiadione.
2. Why is chronic rodenticide better than acute rodenticide?
The advantages of chronic rodenticide are: small dosage, rats will not refuse to eat until they die, so the rodent control effect is good and the chances of livestock poisoning are few. If you are poisoned, you can also use a special antidote (vitamin K 1) to rescue you. Chronic rodenticide conforms to the habit of mice. Rats eat intermittently and stop eating. However, most kinds of chronic rodenticides are not very toxic at one time, and there is no uncomfortable feeling after eating them. Can be eaten for several days, the cumulative toxicity will be very strong, mice will die. Chronic rodenticide has a slow effect. Most mice died after taking medicine for more than three days, and there were no serious symptoms before they died, so they were still eating poison bait when they died. Therefore, when a large number of rats died, almost all rats ate enough lethal dose of rodenticide, even if some rats stopped eating or moving, they would inevitably die. There is no problem that a large number of dead rats scare away survivors. Chronic deratization can kill many kinds of rodents, and it is safe to use in a large area, with good deratization effect and more dead rats. It is the main weapon to kill rats at present. Chronic rodenticides mainly refer to anticoagulant rodenticides, such as bromadiolone and Dalong.
3, buy, put rodenticide matters needing attention
(1) Buy rodenticide from qualified departments.
(2) Understand the ingredients of rodenticide used and the safe detoxification methods.
(3) Put rodenticide out of the reach of children.
(4) If you eat by mistake, send it to the hospital immediately.
4. Use rodenticide safely
According to some data, pesticides and rodenticides are the first two kinds of poisons that cause poisoning in China, accounting for 29.22% of pesticides and 28.62% of rodenticides. The dosage of pesticides in China is much more than rodenticide every year, so in proportion, acute toxic rodenticide is the primary factor of poisoning death of ordinary people in China.
Before 1950, acute rodenticide was mainly used to kill rats, and tetramine was commonly used. These drugs are very toxic and have no antidote, so they have been banned for a long time. At present, chronic rodenticides are usually used, mainly anticoagulants. Rats have mild symptoms after taking the medicine, which is not easy to arouse the vigilance of the same kind, and the concentration is lower, which is safer for people and animals. Antidotes are commonly used in clinic and are easy to rescue after poisoning.
There are also some interesting ways to kill rats:
Cement derating:
Stir-fry rice, flour, corn flour and other foods, add a little sesame oil, then mix it with dry cement and put it in places where rats often appear. Cement is tasteless, and mice will swallow it when they smell food and oil. After eating, the cement will inhale the water in the intestine and solidify, leading to constipation and abdominal distension and death.
Viscose rodent control:
The rodenticide adhesive developed by Tianjin Organic Chemistry Experimental Factory is made of non-toxic polymer materials with strong adhesion. Experiments show that when the rodenticide is coated on a square foot of paper, the rodenticide efficiency is four times that of the mousetrap. Under the condition of 5-40℃, the validity period is more than three months.
Bucket bait for rodent control:
Use a bucket filled with one-third of water, sprinkle a layer of straw on the water surface to completely cover the water surface, then put some food that mice like to eat on the straw, and then put some boards around the bucket obliquely. When the mouse climbed onto the board and saw food in the bucket, it jumped down and drowned.
Oil bottles lure mice:
Drop a few drops of sesame oil in an empty wine bottle and put the bottle in the hole of the mouse. When mice smell sesame oil, they will squeeze into the bottle, so that they can catch mice.
Empty tube rat catching:
Find a jar or similar container about one meter high (smooth inside), take a piece of tissue paper slightly larger than the jar mouth, gently stick it on the jar mouth, but not firmly, and then put the fried noodles in the center of the paper. When a mouse steals fried noodles, it will break the paper, fall into the jar and catch it.
Porcelain bowl button mouse:
Stick one end of the needle on a ball with adhesive tape, put a little pork on the other end, and then gently press the edge of the bowl on the ball. The needle should be pointed at the bowl, and the mouse pulls the ball when stealing food and is locked in the bowl. When the mouse is caught, hold down the bowl and shake it near the ground. When the mouse's tail comes out of the bowl, it can be caught and killed.
Diesel deratization:
Mix diesel oil with butter and engine oil and apply it around the rat hole. When mice come in and out, they will be covered with oil and dust. When it feels uncomfortable, it will lick it with its tongue. Diesel oil will enter the stomach with digestive juice, leading to digestive dysfunction and death.
Kill mice with mice:
After catching the mouse, put one or two soybeans in its anus, sew it up, and then let the mouse run away. Before long, the soybean will swell, making the mouse uncomfortable and crazy. It will try its best to bite other mice, killing more than a dozen a day, and eventually it will die itself.
Cats kill mice with sound;
Let the cat make a strong vibrato, record its voice on a tape, and then put it in the place where mice often move. After hearing the cat's voice, the mouse will run around. After repeated playing, the mouse became slow, lost appetite, stopped breeding and gradually died.
Ultrasonic deratization:
The ultrasonic mousetrap can emit ultrasonic waves, which impact the brain and optic nerve of mice, causing disorder and even death. The ultrasonic mousetrap above 30 kHz developed in China has good rodent control effect.
