Usually wherever I have had rats, I don’t have mice. It just seems like they chase all the mice out. They can be very difficult to get rid of. Fortunately I have never had them in my house.
I’m a bit curious that all you find is damaged plants. I really can’t remember that problem. Usually it’s turds in the bread drawer or a hole in some type of food package. They usually leave sign. Like said , they can’t control urine and poo. They leave a trail wherever they go and others follow it.
I like to wrap peanut butter on trigger with toilet paper. Might be to valuable for that right now. I also like the chunky peanut butter and usually press a chunk right into the hole on trigger. If you wrap with toilet paper and alternating layers of peanut butter. They will try to eat both and set off the trap. When you still have peanut butter on the trigger and a dead mouse in the trap, maybe you got em all.
