Most of the damage that a structure will sustain is going to stem from the bat guano and urine that they are going to excrete 20 or more times a day. These substances are corrosive to the surfaces inside a structure like wood, metal, drywall, and insulation. Further damage is going to come from the cleaning up process that is going to be extensive in order to fix everything they did. Cleaning up a bat infestation may require the removal of insulation, drywall, wood beams due to the smell and corrosion they experienced from their droppings. Bats are also going to bring other dangers that you are not even going to realize is there until it has made you sick.
