The kitchen screen at home was bitten by rats, and at first I thought it was damaged by something

Yes! Rats cross the street, and everyone shouts and fights. It is recommended to buy sticky mouse glue, and set up a card to spread glue on the way it wants to escape, and it will definitely be caught, otherwise it will patronize.

It must be hiding, I've run into it several times. The rat will not recognize the way when it is hiding from people, unless it comes to your house every day and knows the way very well. You wait, you will know in the middle of the night, put a glass bottle with a big belly and a small mouth, put some sesame oil in it, after the mouse falls into it, because there is oil on the wall of the bottle, it will not be able to climb out, but the bottle should be fixed, and put some books or something outside as a platform, so that the mouse can climb to the mouth of the bottle.

You have to put away the rest of the food in the house, leaving only the bottle, this trick is accurate!

Install a wire mesh café, so that the rats can't bite it.
