I live in a camper and it has holes in the walls and is honestly falling apart and I now have mice and I don't know what to do. I've put poison out and I can't tell if theyve been eating it but even if they do the holes in the walls are too big to fill (I'm talking like the floor is disconnecting) I can't afford to move anywhere else, I've tried using those wooden traps and I've put more poison. I can hear them and it's stressing me out. I have a dog and I am trying my best but I don't know how to fix it. I will quite literally do anything.
