I wish I knew, Kathy. One day I saw insulation sticking out from the roof vents. Upon further inspection, my neighbor told me about the mama with the little babies up there - eeeek! They are so destructive. Took a good 2-3 months to get the last of them out of the attic.

I made it through one box of receipts and fished out several invoices. More invoice fishing tomorrow!

Thanks so much, Anne
