Rats, the first of the four pests, used to be very common in rural areas. Why are there so few now?

In the past, there were many rats in the countryside. Even if a few cats were kept at home, it would not delay the visit of rats. Things that have been bitten by rats are often found at home, and food is often ruined by rats. Occasionally, the small wardrobe where clothes are kept at home has also been chewed. When sleeping in the country at night, rats can always hear the sound of coming out for food at midnight. I simply hated this little thing at that time.

There are really few mice now, and the countryside has become very clean. It is almost impossible to see mice biting anything or stealing food. Are rats extinct? I don't think so. There must be mice now, but there are few mice at home, because people's houses are relatively strong now, and rural buildings are now made of cement. It's difficult for rats with such concrete walls to get in, and windows and the like are well sealed, so the chances of rats wanting to enter the house are very low.

Moreover, even the countryside has changed a lot, and the hygiene is in place, so it is no longer as chaotic as before. When rural grain is ripe, it is also harvested mechanically and sold after harvesting. There is little food hoarding at home, and there is nothing to feed at home, so rats will not patronize again.

There should be more rats in the wild now, and foraging in the wild is relatively simple. Now, there are few natural enemies of mice, such as eagles and weasels. Rats are basically no longer worried about encountering natural enemies when foraging in the wild, and it is easier to find food in the wild than to steal things from farmers' homes. Rats are not common now, and they are obviously reduced. There are environmental and natural reasons, and some people have caused environmental pollution. It is also a good thing that ordinary people have fewer mice.
