North Shore Wildlife uses safe, humane bat exclusion methods to get bats out of your home — then we seal the entry points so they can't move back in.
Bats don't need a big opening to get into a house. A gap around a roofline, soffit, chimney, vent or other exterior opening can be enough.
The mistake homeowners make is simply plugging the hole. If bats are still inside, sealing an active entry can trap them in the structure and create a much bigger problem.
North Shore Wildlife takes a different approach: inspect first, exclude humanely, then seal the structure thoroughly.
We address the entire problem: where they're getting in, how they're getting out, what they've left behind, and how to keep them from coming back.
We inspect the attic, soffits, roofline, vents, chimney areas and other likely entry points to identify active bat access.
One-way bat valves are installed at active exits so bats can leave the structure but cannot simply fly back inside.
Once the bats have safely vacated, we close potential re-entry points using durable, appropriate exclusion materials.
When needed, we can address accumulated guano, contaminated insulation, odors and attic sanitation.
Wildlife contamination can leave unpleasant odors behind. We can provide appropriate cleanup and deodorization solutions.
Your completed exclusion is backed by written warranty terms so you know exactly what is covered.
Bat colonies are protected in Massachusetts, so professional exclusion isn't something that should be done whenever it's convenient.
The permitted exclusion windows protect young bats that cannot yet fly and help ensure the colony can leave the structure safely.
A bat valve is a one-way exclusion device placed over an active exit. It gives bats a safe way out of the structure while preventing them from using that opening to get back inside.
At the same time, other potential entry points are sealed. Once the colony has safely vacated, the exclusion device can be removed and the final opening sealed.
A bat colony doesn't belong inside your house. The sooner the entry points are identified, the easier it is to plan the right exclusion.
Scratching, fluttering or movement around the attic can become a nightly disturbance.
Accumulated guano and urine can create odor, staining and sanitation concerns.
Bats sometimes end up inside the occupied portion of the house through walls, ceilings, chimneys or other openings.
Don't do it until you know the bats are out. Sealing an active entry point can trap bats inside the structure. The correct solution is exclusion first, sealing second.
We don't guess at where the bats are getting in. We inspect the structure and build the exclusion around the actual problem.
Locate active exits and potential entry points around the structure.
Install one-way bat valves at active exits.
Close other potential re-entry points with durable materials.
Address guano, contaminated materials, odors and sanitation when needed.
Receive written exclusion warranty terms for completed work.
The first step is a professional inspection. We'll identify the problem, explain what needs to be done, and give you a clear path forward.
📞 Call North Shore Wildlife 978-872-6633A bat colony inside a home should be addressed professionally. Bats are wild animals and can carry rabies, although most rabies exposures occur through direct contact. If you find a bat inside your living space, do not handle it. Contact a qualified wildlife professional for guidance.
Not if bats may still be inside. Sealing an active entry point can trap bats in the structure. Proper exclusion uses one-way devices and a carefully timed sealing process.
Massachusetts guidance allows colony exclusion during the month of May and again from August 1 through October 15. Exclusion should not be performed during the maternity period when flightless young could be trapped inside.
Call us anyway. We can inspect the structure, identify likely entry points, document the problem and help you plan for the next compliant exclusion window. The exact work that can be performed depends on the situation and applicable regulations.
Yes. Massachusetts wildlife guidance notes that bats can use openings around one-half inch or larger, which is why effective exclusion requires more than simply closing the obvious hole.
Yes. When cleanup is part of the project, we can address accumulated guano, contaminated insulation, odor and attic sanitation using appropriate cleanup procedures.
Yes. Completed exclusion work comes with written warranty terms. The exact coverage is provided with your proposal and completed work.
