What are the different types of poison gas to kill rodents? What are the main drugs used for chemica

Various measures are taken to destroy the adaptation environment of rodents, inhibit their reproduction and growth, and cause them to die.

Heighten. Deep ploughing, irrigation and afforestation can be combined with production to worsen their living conditions. This method must be used in conjunction with other methods to be effective. Cats and owls, which protect the natural enemies of rodents.

Badgers, cats and most snakes, which feed on rats, to control the rodent population. Use rat traps and rat traps to catch mice. This method is not suitable for large areas or high pest densities.

This method has good effect and quick effect, and has a wide range of adaptation, so it is necessary to exterminate rodents in a large area. However, it is necessary to pay attention to the selection of high efficiency, low toxicity, low residue, no pollution and low risk of second poisoning, so as not to cause physiological resistance to pests.

rodenticides. (Glycolin, Sodium Salt of Enemy Rats, Poisonous Rats Phosphorus, Dalong) Learning rodent extermination method is the most economical method of large-scale rodent extermination. Attention should be paid to safety when using to prevent human and animal poisoning accidents. Chemical rodent extermination can be divided into poison bait method, poison gas method, poison water method, poison powder and poison paste method.

Commonly used rodenticides: Acute and chronic types of intestinal rodenticides. Those that can be effective after only one dose are called acute rodenticides, or fast-acting drugs. It takes several days to take the drug for a significant effect called chronic rodenticide, or slow-acting drugs, the former is mostly used in the wild, and the latter is mostly used in residential areas.

Rat poison delivery is best carried out by trained personnel. The feeding methods are: bait by hole:

Suitable for field mice with obvious burrows; Stocking by rat tracks: house mice in most areas.

The hole is not easy to find, but the activity place is easy to determine, and this method can be used to administer medicine; Equidistant release: Eliminate wild mice in open areas, and release a bunch of poisonous baits at certain intervals in each row and column according to the checkerboard method; Uniform stocking: generally limited to field mice, suitable for high rodent density, wide and sparsely populated places; Strip Delivery:

The medicine is administered in a straight line at regular intervals for the extermination of field mice. In the family, rodent control bait can be deployed at night and collected during the day to avoid accidental injury to children, poultry and animals; You can also use the method of poison bait box, which can be made of local materials, which varies from time to time and from mouse to rat. The storage of the poison bait box is generally not more than 5 days, if there are no rats entering for more than 5 days, the location should be changed.

When exterminating house rats, each household puts poison bait boxes.

One or two are sufficient, but they should be in the right place, checked frequently at the beginning of use, and replenished fresh poison bait in time. After the rat density decreases, check it once a month to ensure safety.

Highly toxic rat poison can cause death in rats within minutes or hours of ingestion. After the rat eats the acute poisonous rat poison, the symptoms are severe and very painful, and the rat dies quickly, often outside the nest. As everyone knows, this is just "taboo", rats are alert by nature, a mouse fell to the ground after taking medicine, the same kind of people immediately dispersed, and will not touch this poisonous bait again, this is actually "scaring the snake", so that most of the rats can escape.

Moreover, most of the first mice to take medicine are those old and weak, sick and disabled mice, and the strong mice survive, and the rat population is artificially optimized, and the remaining ones grow better, and the breeding offspring are stronger, making it more difficult in the future. Therefore, acutely toxic rat poison is not provided in rodent control activities. There are two types of poison gas rodent extermination:

One is a chemical fumigant, and the other is a fumigant. Commonly used chemical fumigants are aluminium phosphide and chloropicrin, as well as fumigants in different formulations.

Fumigation of rodent extermination Some drugs are easy to vaporize into toxic gases at room temperature or produce toxic gases through chemical reactions, which are commonly known as fumigants. The rodent extermination method that uses toxic gases to inhale rats and poison them to death is called fumigation and rodent extermination. Advantages of fumigation and rodent extermination:

It is mandatory and does not have to take into account the habits of rats; Do not use grain and other foodstuffs, and the results are fast, and the effect is generally good; It also has an insecticidal effect; It is safer for livestock and poultry. Disadvantages: It can only be used in a confined place; It is highly toxic, fast-acting, and easy to be poisoned when used carelessly; The usage is larger, sometimes the cost is higher; When fumigating and killing the rats in the cave, it is necessary to find the hole, administer medicine, and plug the hole, and the work efficiency is low.

The use of this method has limitations, and it is mainly used to kill rodents in warehouses and other closed places, and can also kill rats in caves. At present, there are two types of fumigants: one is chemical fumigants, such as aluminum phosphide, etc., and the other is rodenticide.

The common characteristics of chemical fumigants and fumigants are: mandatory, fast-acting, generally safe for non-target animals, no need for bait, but the expenditure is more, the work efficiency is low, and the effect on some rodents is poor.

The ranking of the most feared odors in rats is as follows:

1. Mint flavor.

Many people like the smell of mint and think that the taste of Hexiao is fresh and good, but it is not the same thing for mice. They even hate it. You can put some mint leaves in places where rats are frequented so you can get rid of rats.

2. Mothball.

Mothballs smell good. Everyone uses it to keep insects away. The elders of the family like to keep it in the closet. In fact, mothballs can also drive away mice. If you find rats in your home, put some. Rats don't like the smell of Zen cheats.

3. Cat hair. Although cats don't catch mice much these days, mice are still afraid of cats. If you don't have a cat at home, you can go to a friend and get some cat hair in a place where rats are frequented, which will keep the rats away.

4. Chili peppers. 5. Laurel leaves.

Methods of rodent extermination

1. Viscose rodent extermination: There is a non-toxic polymer material developed rodent viscose on the market, its viscose ability is very strong, and the experiment proves that the rodent killing efficiency is four times that of rat trap hunting and killing by coating this glue on a square piece of paper.

2. Oil bottle to lure mice: drop a few drops of sesame oil in the empty wine bottle, put the bottle at the mouth of the mouse hole, the bottle mouth is facing the hole, the mouse will squeeze into the bottle when it smells the smell of sesame oil, because it can not drill out again, so that the mouse can be caught.

3. Ultrasonic rodent extermination: Ultrasonic rodentide can emit a kind of ultrasonic wave, which can impact the brain and optic nerve of mice, causing disorders until death.

4. If there are not too many mice, you can use methods such as sticky mouse boards, mouse cages and mouse traps.

5. Diesel rodent extermination: Mix diesel with butter and engine oil, smear around the mouse hole, the mouse will rub a body of oil when it enters and exits, sticks to a body of dust, and feels uncomfortable to lick with the tongue, and the diesel fuel enters the stomach with the digestive juice, so that the digestive function is abnormal and deadly.

1.Acute rodenticide, also known as acute single-dose rodenticide, can kill rodents by eating enough lethal amount of poison bait at one time. The advantage of this kind of drug is that it acts quickly and consumes less food, but they are not safe for humans and animals, and it is easy to cause secondary poisoning.

Such drugs include zinc phosphide, fluoroacetamide, rat phosphorus, rat poison rat phosphorus, strong brominated rat phosphorus, bromazi, dibromigen, etc. Fluoroacetic acid amine and rat poison strong, glycofluoride due to strong toxicity, no specific antidote, easy to cause human and animal poisoning, the state has been expressly banned. 2.

Chronic rodenticides, also known as slow-acting rodenticides, can be divided into the first and second generations of anticoagulant rodenticides. The first generation of anticoagulant rodenticides, such as anti-rat sodium salt, rodenticide, rodenticide (rickamide) rodenticide, chlorantiomicide, etc., should be administered for several days if the ideal rodenticide effect is to be achieved. The acute virulence of the second-generation anticoagulant rodenticide is relatively strong, and the rats can be lethal after eating two or three times, and the rats that are resistant to the first-generation rodenticide can also be killed.

Such drugs include bromadiolone, dalong, kill it, thidiolone, etc.

Search: What effective rodenticide drugs and tools are available?

According to the speed of action of rodenticide after entering the rat body, it is divided into two categories: acute rodenticide and chronic rodenticide.

Acute rodenticide, also known as acute single-dose rodenticide and dangerous rat poison, can be fatal if rodents eat enough lethal bait at one time. The advantage of this kind of drug is that it acts quickly and consumes less food, but they are not safe enough for humans and animals, and it is easy to cause secondary poisoning. Such drugs include zinc phosphide, etc.

Chronic rodenticide, also known as slow-acting rodenticide and safety rat poison, can be divided into the first generation of anticoagulant rodenticides, such as anti-rat sodium salt, raticide, rodenticide fan (rickamide), rodenticide, chlorine anti-rat, special rodenticide No. 2, etc. This type of rodenticide needs to be administered for several days in a row if it wants to achieve the desired rodenticide effect. Another type of chronic rodenticide, called the second-generation anticoagulant rodenticide, their acute virulence is relatively strong, rats can be killed after eating once, and rats that are resistant to the first-generation rodenticide can also be killed.

This kind of rat poison has bromodiolone, Dalong, killing it and so on.
