Bat Removal
Custom-fitted one-way excluder doors let bats leave to feed at night but block them from coming back. Most bats are gone within a few days, and setup is usually done in a single visit.

Do you have bats?
Common signs it's time to call a specialist
Bats can squeeze through openings the size of a pencil. Most homeowners don't realize they have a colony until they notice one of these.
Droppings (guano)
Dark pellets on siding, window sills, decks or in the attic.
Scratching or squeaking
Noises in walls or ceilings at dusk and dawn.
Stains near gaps
Dark, greasy rub marks around soffits, chimneys and vents.
Bats at sunset
Bats emerging from your roofline as the sun goes down.
A bat in the living space
One indoors often means more are roosting nearby.
Odor in the attic
A strong ammonia smell from built-up droppings.
What we do
Help for every bat nuisance problem
From a single bat in the attic to colonies in church steeples and municipal buildings, we handle the job start to finish.
Bat Prevention & Sealing
We seal every other gap, crack and seam with construction-grade materials so the colony can't find a new way in. Permanent bat-proofing for your home or building.

Our 5-step process
Humane exclusion, done right the first time
No chemicals, no trapping, no harm to the bats. Just a proven process that keeps your building sealed.
Exterior Inspection
We inspect the building top to bottom to find every gap bats use to get in and out — and document it all with photos.
One-Way Door Install
Custom-fitted excluder doors go on active entry points so bats can leave to feed but can't return.
Building Sealing
All other openings are sealed with construction-grade materials so bats can't find a new way in.
Monitoring
We come back within a few weeks to confirm the bats have left or are leaving.
Door Removal & Final Seal
Once the bats are out, we remove the excluder doors and permanently seal those last openings.
Timing matters. Wisconsin's bats are protected, and exclusions have to be planned around the summer pup season and winter hibernation. Call early — even off-season, we can inspect now and schedule your exclusion for the right window.

Why Bat Specialists
Specialists, not generalists
General pest companies treat bats as one item on a long list. We focus on bats alone — and that's made us Northeast Wisconsin's go-to team since 2006.
Trained in wildlife biology
Our founders hold B.S. degrees in wildlife management and biology from UW–Stevens Point. We know bat species, behavior and hibernation patterns.
No subcontractors, ever
The person who inspects your home is the person who does the work. You deal with us from first call to final seal.
Photos of everything
We show you exactly where the bats are getting in and what we did to fix it — total transparency.
Humane & eco-friendly
Clean, safe methods with no pesticides, traps or netting. The bats go on eating mosquitoes — just not from your attic.

FAQ
Questions we hear a lot
Don't see your question? Reach out — we're happy to talk through your situation.
Found a bat in your living space?
Don't try to handle it with bare hands. Close interior doors, open an exterior window or door, and give us a call so we can find how it got in.
(920) 468-3556Which locations do you service?
We're based in Green Bay and serve the surrounding area, including Appleton, Oshkosh, Manitowoc, Sturgeon Bay and Shawano. We generally travel about 45 minutes from Green Bay and can go farther in certain situations.
Do you charge for an inspection?
Yes, but it's minimal. Inspection fees typically run $50–$90 depending on your location. Contact us for current pricing in your area.
How long does bat removal take?
Setup of the excluder doors and sealing can often be completed in a single day. Most bats are gone within a few days, and we return within a few weeks to confirm before the final seal.
Will the bats be harmed?
No. Our exclusion process is completely humane — we never use pesticides, traps or netting. One-way doors simply let bats leave on their own and keep them from returning.
Can you remove bats any time of year?
Wisconsin's bats are protected, so exclusions need to be timed around pup season in summer and hibernation in winter. We can inspect year-round and will recommend the right window for your property.
Do you subcontract the work?
Never. We're a locally owned small business and handle every inspection and removal ourselves, so you deal only with us from start to finish.
Do you take care of animals besides bats?
No — bats are our only focus. That specialization is what sets us apart from general pest control companies.
