Ferndale
A Ferndale attic full of live bats, and a one-way door out
Lots of live bats were roosting in a Ferndale attic. We sealed the entry points and installed a bat valve so the bats could leave on their own but not get back in.
Sudden Valley
Bats moved in after a tree hit a Sudden Valley home

A trip out to Eliza Island to find how bats were getting into a custom-built cabin. The culprit: an old tree-damage repair along the roofline.
Questions
Are bats protected in Washington State?
Yes. Bats are beneficial and protected under state wildlife law. They can't be poisoned or exterminated, so they have to be excluded humanely.
When is bat exclusion allowed in Washington?
To protect flightless pups, humane bat exclusion is done between mid-August and mid-October. We inspect entry points and time the work to that window.
How do you get bats out of a house humanely?
We install one-way devices over their roost gaps. The bats fly out at dusk to feed and can't get back in. Once they're out, we seal the gaps.
Is bat guano dangerous?
Built-up guano in warm, damp attics can carry fungal spores that cause lung infections. We give guidance on safe containment and removal.
