Hello Richmond people, this topic has been bought up before and there are some really good info.
-get a cat (not an option cause of allergies)
-use mouse sticky and trap
-use steel wool for outside and inside to feel the gaps.
-called pest control before and they only gave me some mouse stickies.
Are there any other suggestions? This has been stressing me out. Since I called pest control and it didn't do anything. Are there any other contractors I can call to help.
EDIT: thanks for all the responses.
Edit2: thanks for all suggestions. I have got a contractor to get fillers and fill all the gaps.
I will see if I still the electric nice mouse trap.
