What are the benefits of the presence of rats for humans?

Although rats are pests, rats are also an important part of the biological chain, being an energy supplement for cats, snakes, owls, etc., that feed on rodents. If there were no rats, the number of animals that feed on rats would also plummet, and the decline in the number of these creatures would lead to changes in other species, and any link in the biological chain could cause a butterfly effect.

In addition to the first food, in the biological chain, the mouse can also be a predator, the mouse will eat the eggs when they encounter the eggs in the underground nest, why eat vegetables if there is meat to eat? So rats also eat a lot of insects in nature, grasshoppers, cockroaches, beetles and so on.

If there were no rats, the number of pests in the wild would increase a lot, and the number of cockroaches in residents' homes would also increase significantly! Because many rats in the city live in the sewers, the most common things in the sewers besides leftovers are cockroaches and flies (maggots). So, one of the natural enemies of cockroaches is gone, do you want to see your own cockroaches and flies overflowing?

So when we do pest control in the city, it is called "four pests sanitize", cockroaches, mosquitoes, flies and mice are killed together, rarely only one is killed alone, although they are very annoying, but in some aspects there is a very subtle connection.

Of course, the biggest benefit of mice to humans is the experimenter, in physics, medicine and many other experiments, mice always take on the obligation of the first attempt, and have made great contributions to the development of human pharmaceutics. Finally, there is food, in Fujian and Guangdong, rats can become a delicacy on people's plates, I don't know as a northerner, and I don't dare to try it.

1. Environmental rodent extermination: Rats need water, food and hidden habitat conditions to survive and reproduce. Therefore, creating an environment that is not suitable for their survival can greatly reduce the rodent population in a place and can easily consolidate the results of rodent extermination.

Therefore, we must first do a good job of environmental hygiene, remove weeds around the house, random piles of items, often clean indoor and outdoor hygiene, all kinds of utensils and sundries are tidy, clothes, wardrobes, books, shoes and hats should be checked frequently, so as not to make rodents nest.

Cut off the food of rats: rat food not only includes human food, but also includes feed, garbage, food industry scraps, feces, etc., these things should be stored in a covered and no crevices container, so that rats can not get food and passively eat the poison bait, in order to achieve the purpose of eliminating rats.

2. Physics rodent extermination method: also known as instrument rodent extermination method, it has been used for a long time and has many application methods. It not only includes a variety of special mousetraps, such as rat traps and rat cages, but also includes pressing, stuck, closing, clamping, turning, filling, digging, sticking and so on.

Physics rodent extermination also pays attention to certain science and technology, such as placing rat cages (clips) at the mouth of the rat hole, which should be at a certain distance from the rat hole, and sometimes use some camouflage to improve the killing rate; The bait on the rat cage should be fresh and should be a favorite food for rats. Generally, the rats are not easy to basket on the first night, because there is a "new reaction", and the basketing rate will increase after two or three days.

3. Chemical rodent extermination: also known as drug rodent extermination, it is the most widely used and effective rodent extermination method. Drug rodent control can be divided into intestinal poison rodent extermination and fumigation rodent extermination.

The intestinal rodenticide used as rodent control is mainly organic compounds, followed by inorganic compounds and wild plants and their extracts. Gastrointestinal rodenticide requires good palatability to rats, will not refuse to eat, and has appropriate virulence. It is mainly made of various poisonous bait, with good effect, simple use and large amount.

The second is poisonous water, poisonous powder, poisonous glue, poisonous foam, etc. Fumigation and rodent extermination, such as aluminum phosphide and chloropicrin can be used for warehouse and ship fumigation and rodent extermination.

4. Biological rodent extermination method: including two aspects: one is the use of natural enemies to exterminate rats, there are many natural enemies of rodents, mainly carnivorous small beasts such as weasels, wild cats, domestic cats, foxes, etc., birds of prey such as eagles, owls, etc., as well as snakes.

Therefore, protecting these rodent natural enemies is beneficial to reducing rodent infestation.

5. Ecological rodent extermination: that is, through improving the environment, including rodent-proof buildings, cutting off rat food, farmland transformation, doing a good job in indoor and outdoor environmental sanitation, and removing rodent hiding places, etc., that is, controlling, transforming, and destroying the living environment and conditions conducive to the survival of rodents, so that rodents cannot survive and reproduce in those places. Ecological rodent control is an important part of comprehensive rodent control.

As long as it is a rat, it should not be of any benefit to us humans, it must be destructive, whether it is a mouse, a mole, a vole, etc., it should be the same animal.
