So it seems a family of flying squirrels has moved into the insulation in the ceiling of my garage. They have destroyed the insulation and peed all over everything. Now I have to pull out 900 SQFT of R30 insulation, strapping and sheet rock. Then put it all back in before winter on a budget of oh about $0! I am sure my family wants to "Save" the little buggers but I may have other plans for them. Any suggestions on how to keep them out? Thanks. End rant.[S
