Common Questions About Guano Removal in Bryn Mawr-Skyway, WA

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.

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.

Will the smell go away after cleanup?

Often yes, once the guano and soaked materials are removed and the area is treated. Deep stains in wood or drywall may need extra treatment, and the crew can say what to expect.

Who pays for guano cleanup in a rental?

It depends on the lease and local law. Tenants should tell the landlord or manager right away. A landlord, an attorney or a tenant rights group can say who is responsible.

What rules apply to guano cleanup in Washington?

Worker safety follows OSHA rules for hazardous dust, and waste disposal is handled according to local requirements. Rules about moving or excluding bats and other wildlife can vary by species and season, so check with a wildlife professional first.

How do I get rid of the guano smell?

The odor comes from droppings and urine soaked into wood and insulation, so the fix is removing the source and treating surfaces. Air fresheners only cover it. Deep stains in wood may need extra treatment.
