How to know if you have bats in your attic.

Here are the top signs that bats have infested your attic. If you hear chirping bat sounds from the attic or very close to the home at night or before dawn you may very well be hearing bats. Bats are nocturnal animals which mean that they sleep during the day and will only come out at night. Guano droppings produces an almost toxic odour that s similar to ammonia and a definite sign bats are somewhere near.

Check for dark brown stains around your roofline dormers vents and roof trim. Bat skin secretes an oil that rubs off on the walls of your attic leaving a tell tale sign that you have unwanted guests. Bats usually leave their droppings in apparently designated areas so it s almost impossible not to see it. Stains on entry points at the house of corners below the roof might be another sign.

You see piles of black droppings on your attic insulation. Like most of the signs above guano around the home isn t necessarily a sign but if you see it in your attic then you know you need to call someone. Piles of droppings in one corner of the attic or near the entry point droppings on attic insulation stains on the attic walls from urine.
