Jiangxi Dayu rewards 5 yuan for killing rats. Under what circumstances are there the most rats?

Rats are very survivable animals, so they can survive anywhere humans have been. But they prefer to stay in dark places with bacteria, such as dark and humid sewers, public toilets, kitchens with food scraps at home, living rooms with snacks or other foods, sundries and garbage dumps at home and so on.

These places are people's least favorite, so people have never had a good impression of mice. Rats themselves like to move back and forth between infected places and clean places, and then carry and spread pathogenic bacteria through their feet, body hair and even their stomachs. This is also the reason why rats have become one of the four pests. Moreover, rats have the strongest reproductive ability among mammals, so the number has always been high, and almost every household has been persecuted by rats.

Now, in Dayu County, Ganzhou City, Jiangxi Province, the "national rodent control" campaign has encouraged the general public to carry out rodent control activities spontaneously by setting up mousetraps, mousetraps and sticky boards. What's more interesting is that this activity is a "prize collection", which will be rewarded according to the standard of 5 yuan/only, just provide the rat tail. Under such conditions, rodent control activities will definitely bring a wave of climax, which will not only destroy what everyone hates, but also get a reward. Why not?

Such activities should still be able to control and destroy a large wave of rats, and people only need to go to places where rats often pass, or find them in their favorite environment, so that they have nowhere to hide. But in order not to have rats in the house, we should keep the house clean and tidy, have light and ventilation every day, and carefully clean up food residues.
