Reply To: Best way to mouseproof a basement in BP, with Shuls and schools on every block?

Buy mint oil and some cotton balls. Soak some cotton balls in the oil and place them in every corner, and at intervals along the walls.

Mice naturally run along walls because of their poor eyesight. They also have a natural aversion to mint, and will avoid it.

I have friends who got rid of mice using this method. They claim it worked within days.
