We've had plenty of mice over the years that have found their way into our
house.
During a recent kitchen project, I had a new stainless steel sink setting in
the basement. When we got around to installing it, there was a dead mouse
in it. Climbed or fell in and couldn't get back up the steel sides.
I keep traps set all the time, but I'm trying to seal off the possible ways
they get in.
Someone gave me this hint for finding the little holes in the house. On a
windy day, search for the places you feel cold air coming in, because when
the wind is from the opposite direction, the mice will follow the warm air
coming out, and find the secret route into the house. I filled a hole with
caulking again this week.
Blessings,
Tom
