It'* pretty frustrating, I know.
Our country mice loved canned dog food on the traps. I could catch 4 or 5 just during the late night show. Finally found hole where the septic pipe sealer had aged and cracked and I was seeing blue sky from inside the basement.
Other times woodpeckers would go after little worms burrowed in the wood siding. Then the mice would enlarge the holes. The little devils would eat right through the steel wool patches. Finally had to mix plaster into the steel wool.
Caught one once by the tail on our basement block wall, thinking I would just toss it out the door and spare it'* miserable life. The @#$%% thing bit me! Talk about an ingrate.
They've also gotten in my auto air intakes, chewed up my truck vent blower supports, chewed through the magneto wire on my snowblower, you name it. The auto dealer said to keep a few mothballs under the hood somewhere You definitely don't want them getting into and dying in your air vents!
Hang in there -- you're doing all the right things.
