If there are rats in the room, will the rats climb from the end of the bed to the head of the bed? W

The rat must have been running for a place to eat, how could he climb into the toilet? What do you think? Is he going to fall into the water and drown? No way, he must have followed the wall to find a place to eat. His sense of smell is very sensitive.

When the rat is full, will it lick the empty bowl? Impossible.

Not necessarily the exhaust flue, maybe there are other passages where there are holes, where there are holes, rats can climb, and there will be rats on the 7th floor where I live, which come in from the hole in the air conditioning pipe. I have also tried a lot of ways to catch mice, it is recommended that you use a good quality genuine universal sticker, pasted in the place where mice must pass, before our dormitory used this one night to paste a whole 4! Be sure to post it on the side of the toilet door, I hope it will be useful to you!

The squatting toilet will come up sometimes, and you can keep a cat at home so that the mice don't dare to come in.

Plug holes in the corners of the house and around the toilet, including the connections between downspouts and sewers. It is most environmentally friendly to use a sticky mouse board in a place frequented by rats, but it takes a long time to stick a mouse in one place before you can stick one again. Good luck!
