In South Lyon, MI we received a call about bat guano in the basement. Upon inspection of the basement we located these droppings and determined them to be Norway rat droppings. Also upon further inspection of the basement, attic, and home we identified there to be mice activity and bats in the attic. Below you will see the picture of a mice entry point into this basement home. The bats in the attic had done significant damage to the insulation. The insulation in the attic need to be removed and the attic decontaminated.
