Bat guano in the attic.
Bat guano in the attic.

Homeowner of leonard, MI ( Addison Township) called with scratching in the attic and a bat found in the furnace filter. They hired a another company to exclude the bats from the attic back in August. Upon inspection of the home we found evidence of mice in all three attics. There were some signs of bats in the attic at one point, but we could not determine if it was old or fresh. Once the roof clears of snow we can determine if there remains a colony of bats in the attic. We could not inspect the attic today.
