Tree fell and put a hole in the front of the trailer, just above the window. As soon as we found out we cut the branch off and duct taped over the hole as a temporary measure to keep the water out until we could fix it permanently.
Apparently, mice went in the hole before it was taped. They ate a hole thru the tape. I guess they went back in because the patched hole has another hole.
An inspection inside the trailer shows no sign of entry inside thru the interior paneling.
My first thought was to pour poison pellets in the hole and tape it up again. Repeat until there is no sign of coming out again. Then permanently patch the hole.
I fully realize that will leave dead ones between the wall panels and siding.
Any other ideas?
