We recently moved my mom into a mobile home on our property. We need to increase insulation around the base of the house, and often see straw bales used around the perimeter of a house for insulating. Will doing this attract mice to the house? We have had a lot of mice trying to move in this summer - and in the midst of battling the beasties, REALLY don't want to inadvertantly issue any "invitations" to any dwellings, ya know? Thanks for your help.
