Mice in walls
I have mice in the walls of my townhouse. Previous pest control came and set traps and closed all the walls inside the home and outside. I haven’t seen a mice in over a year. My neighbor was doing construction and once the construction ended i haven’t heard mice in the walls in like 8 months. However, last week i heard the mice in the walls and again this week. I have opens up the walls before and put in poison. Is there any pest service anyone has had positive experience with that can assist with the mice in the walls? I know we need to find the entry point but it’s a townhouse so I’m not sure how helpful that would be ?? I am open to opening the walls every so often and putting poison but that doesn’t seem beneficial long term. also they’re only behind my walls in the kitchen from what i hear. Nothing is inside the home .
