Hi,
You are on the right track. Wait until they are out and plug it!
Hard to predict, but sense they are usually out in the late morning when warm
out or afternoon.
Spent a lot of money (probably around $700) with a professional trying the
"right" way.
A waste of time, every time they came different ideas, more money.
First they said it was mice. Through about 30-40 bags for mice at a couple of
dollars a bag.
Then said it was both, and now have to deal with squirrels (which it always
was)
They claimed there was a squirrel in one of their traps. It is was in a bag,
never showed it to us, we asked.
Still noise in the attic.
Never any progress.
They said have to trap them first before plugging.
Had a contractor block openings, never problems after that.
Keep them out, they will find another house with easier entrance.
Cheers
David
