Bat Guano Removal in Mosinee, WI Attics and Barns

Histoplasmosis is a lung infection linked to a fungus that can grow in soil enriched by droppings from birds and bats. Guano cleanup is designed to keep those spores from being breathed in.

Common Questions About Guano Removal in Mosinee, WI

How do I know if I have bats in my attic?

Common signs are dark droppings that crumble, stains on walls near gaps, a strong ammonia smell and squeaking or scratching at dusk and dawn. Droppings often collect in piles below entry points. A wildlife professional can confirm it.

Can you get sick from bat droppings?

Yes, mainly from breathing in dust from dry droppings. Risk is higher with old, heavy buildup in enclosed spaces. People with asthma, lung conditions or weak immune systems need extra care and should stay out of the area.

What if droppings are on a roof or high ledge?

Roof and high ledge work needs fall protection and care around other people. Crews can remove and wash droppings there, and a property manager or owner can set up access.

Can I clean a small amount of guano myself?

Sometimes. For a small spot, wear gloves, eye protection and a mask, wet the droppings lightly and wipe them up. Do not sweep or blow them dry. Thick, old or large deposits and attics are better left to a team.

Is guano dangerous?

It can be. Dry guano releases fine dust, and some bird and bat droppings can carry a fungus linked to histoplasmosis, a lung infection. Many people never get sick, but older, heavy deposits carry more risk. Avoid stirring it up.

Will insurance pay for guano cleanup?

Sometimes, but not always. Many homeowners policies exclude damage from animals that builds up over time, and wording differs. Call your insurer before work starts, take photos and keep receipts.
