Can potassium permanganate kill rats, and are rats afraid of pesticides?

Chemical rodenticide.

Chemical rodent control 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 and poison gas method.

1) Poison bait method.

1.Commonly used rodenticides There are two types of intestinal rodenticides currently in use: acute and chronic. 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.

1) Zinc phosphide: gray powder, with significant garlic taste, insoluble in water, lipophilic. It is stable when dry, but slowly decomposes after being wet, and reacts quickly when encountering inorganic strong acids to release phosphine gas.

It mainly acts on the nervous system and disrupts metabolism. After poisoning, appetite is reduced, mobility decreases, and often the hind limbs are paralyzed, and finally death. It has a fast acting effect and is a fast-acting drug.

The concentration of poison bait is generally 2 5. The toxicity of this product is not strong, and it is similar to the toxicity of humans and poultry and animals and rodents, so attention should be paid to safety. When the rats that have not died after the first poisoning of this agent are encountered again, it is easy to refuse to eat, and it is not suitable for continuous use.

2) Rat-poisoning phosphorus: This product is a white powder or crystal, which is very difficult to dissolve in water, has no obvious odor, and is relatively stable in a dry state. Its main toxicological effect is to inhibit nerve tissue and intracellular cholinesterase, which is highly virulent to rodents and not selective.

The rat developed symptoms after 4 to 6 hours after eating the poisoned bait, and died about 10 hours later. The palatability of rat phosphorus to rats is good, and the refusal to eat is not obvious when it is encountered again, and the effect of rat poison on field mice and house mice is better.

The toxicity of rat phosphorus to humans and animals is also strong, and the toxicity to chickens is very weak. But it is strong against ducks and geese. Pay attention to safety when using. The common concentration of poisonous rats to kill house mice is that the killing of wild mice can be increased to 1 2.

3) Rat killin: This product is white crystal, insoluble in water, soluble in alkaline solution into sodium salt. Odorless and tasteless, quite stable. It is the most widely used anticoagulant rodenticide in the world and is a typical chronic drug.

The virulence of war-killing is closely related to the number of doses. Take the drug once, and it can be lethal only when the dose is considerable; When taken multiple times, although the total amount of each dose is much lower than the lethal dose of one dose, it may also cause death to rats. It mainly destroys the blood-clotting ability of rodents, damages capillaries, and causes internal bleeding, resulting in anemia, blood loss, and finally death.

It has a relatively slow effect, generally dying 4 to 6 days after taking the drug, and a few individuals can exceed 20 days. Increasing the dose does not hasten death.

If it eats potassium permanganate, it will definitely kill. Because potassium permanganate is a strong oxide, if you don't pay attention to the hand touching potassium permanganate during the test, it will turn black, and eating it will cause the internal organs to be oxidized and blackened, that is, it will be carbonized. It is estimated that the organization will not live long if it is destroyed.

Potassium permanganate can be used for disinfection, of course it is possible to kill the plague, with 3% mixed with water, it will work in 10 seconds.

Potassium permanganate (KMno4, mr=, inorganic compound, dark purple elongated orthorhombic columnar crystal, metallic luster. Orthorhombic crystal system. It was discovered by Westerners in 1659. Chinese common name: gray manganese oxygen.

In the production of chemicals, it is widely used as an oxidant, such as an oxidant for saccharin, vitamin C, isoniazid and benzoic acid; used as preservative, disinfectant, deodorant and antidote in medicine; In water purification and wastewater treatment, it is used as a water treatment agent to oxidize hydrogen sulfide, phenol, iron, manganese and organic, inorganic and other pollutants to control odor and decolorization; In gas purification, trace sulfur, arsenic, phosphorus, silane, borane and sulfide can be removed; In mining metallurgy, oxidants for the separation of molybdenum from copper, the removal of impurities from zinc and cadmium, and the flotation of compounds; It is also used as a bleaching agent for special fabrics, waxes, greases and resins, an adsorbent for gas masks, and a colorant for wood and copper.

Potassium permanganate is used as a disinfectant, deodorant, water purification agent.

Potassium permanganate is a strong oxidant, which releases new ecological oxygen and kills bacteria in case of organic matter, and has a strong bactericidal power, but it is easy to be weakened by organic matter, so the effect is superficial and not lasting.

At the same time as the external oxidation of permanganic acid, manganese dioxide is reduced to form manganese dioxide, which combines with proteins to form protein salt complexes, which and permanganese ions have astringent effects.

It is also used as a bleaching agent, a toxic gas absorber, a carbon dioxide essence preparation, etc.

What a waste to be eaten by rats

It's pretty much the same for bathing

I remember that I used to like to put a small spoon of potassium permanganate in the bath water every day, which was very comfortable! ~

The dosage of insecticides is mainly set for insects, and it is effective for some insects to tease and excavate. Rats are many times larger than insects, so insecticides can make rats feel uncomfortable at most, and they can't play a role in killing the core of the mountain immediately.

1. Naturally expel rats.

2. Put one or two drops of peppermint oil on a cotton ball. Place cotton balls underneath the trash can to prevent rats from crawling in. Place cotton balls at possible entrances for mice, such as doorways or vents.

The cotton balls need to be changed every 5-7 days, depending on the quality of the peppermint oil. Place a few pots of mint potted plants at the entrance. Peppermint can be used both as a cooking and as a repellent.

3. Use ultrasonic to kill rodents (there are many ultrasonic sounders on the market, which can make nasty beeping sounds for mice, which can be bought in local home stores or online).

We can first fry rice, corn, flour and other foods, then put a little cooking oil, and then mix in dry cement, put it in a place where rats often haunt, rats will run over to eat when they smell the fragrance, after rats eat, cement absorbs water in the intestines and solidifies, which will make rats bloated and die.

First of all, the rodenticide glue is smeared in the place where there is rat poison with the thickness of the key, the size of the application is usually 10 square centimeters to paint a piece, according to the scene to decide the horizontal or vertical coating, you can also apply the ointment on the newspaper, paper or wooden board, the most economical way to save the ointment is to achieve intermittent and continuous combination of coating or releasing medicine, one is to let the mouse have no way out, the other is to avoid the extravagance of the coating everywhere, as long as the mouse comes out of the activity can take the initiative to step on the ointment so is enough, Apply a piece or put a coated medicine board at a certain interval at a certain distance, and put the coated medicine board in the aisle, rat hole, rat road, pipeline line, rodent frequent activity field and other places where rodents enter, and can also be applied straight to the above places to smear rodenticide glue, and the coating cloth is best applied to the rodent must be applied on the road through which the rodents must pass through to achieve a particularly fast effect.

No, you can't

The active ingredient of household insecticides is mainly pyrethroid, which is characterized by high filial piety and low toxicity, so the dosage is generally very small, and it can only kill those small insects, and it is difficult to kill large insects, and the resistance of mice is very large, so ordinary insecticides cannot kill mice.

The most effective method of repellent is environmental extermination, which requires water, food, and sheltered habitat to survive and reproduce.

Therefore, creating an environment that is not suitable for rats can greatly reduce the number of rats, and can also make it easy to consolidate the results of rodent extermination.

Therefore, we must first do a good job of environmental sanitation, remove weeds around the house, pile up items at will, often clean indoor and outdoor hygiene, all kinds of utensils and sundries need to be cleaned up, wardrobes, wardrobes, bookshelves, shoes and hats and other places should be checked frequently, do not rat nests.

Cut off the food of the rats, which includes not only the leftover food eaten by humans, but also the feed, sails, garbage, feces, etc., which should be stored in containers with lids and no gaps. So that the rats do not get food, and passively eat the poisoned bait, so as to achieve the purpose of eliminating rats.

Unable to cause fatal injuries to the shed, he just glued it to the ground, and the destruction temporarily trapped the rat's action. As the rat escapes for its life, there is more and more glue on its body, and it will be completely trapped, and as the time chain goes by, the rat will starve to death, so it will take a while.

Poison bait. Lu Lingyan, a poisonous bait made of rodenticide, was put at the mouth of the rat's hole or the place where the rat entered and exited, and the activity passed, so that the rat was poisoned to death after eating.

Poison rat holes. Poison the rat hole with lime, cement, etc., and suffocate the rat in the morning sedan chair.

Use rat traps and rat cages to hunt and kill rats. First cut off rat food, and then use fried food, fruits, fritters and other sweet foods as bait to lure rats to take the bait and kill them in one fell swoop.

Take advantage of the natural predators of rats. Cats, owls, snakes, etc. are all experts at exterminating rats, and protecting these animals can help our hail to get rid of mice.

Buying a cat is lower than a lot of rat poison.

Put some rat poison on top of the rat's favorite food and place it in a place where the rat is likely to pass, such as the kitchen.
