Important: Bat Exclusion Seasons

Bat exclusion is ONLY legal during specific windows in PA & DE: August 1 – October 31 and April 1 – May 14. Performing exclusion during summer (when pups cannot fly) traps babies inside and is illegal. We strictly follow these regulations and will schedule your exclusion during the appropriate window.

Our Bat Exclusion Process

1

Inspection

We identify all bat entry points, assess colony size, and check for guano accumulation.

2

Schedule

We schedule exclusion during the appropriate legal window for your area.

3

Exclusion Devices

One-way exclusion tubes and netting are installed at all entry points.

4

Monitoring

We monitor to confirm all bats have exited (typically 3-7 days).

5

Seal & Clean

All entry points are permanently sealed and guano is safely remediated.

Signs of Bats in Your Home

Scratching sounds at night — Especially around dusk and dawn when bats are most active.
Guano accumulation — Dark, pellet-like droppings that crumble to powder. Often found in attics, on sills, or near entry points.
Ammonia smell — A strong odor from accumulated guano and urine in enclosed spaces.
Visible bats at dusk — Watch your roofline at dusk — bats emerge to feed and you may see them exiting.
Brown staining at entry points — Bats leave oily brown staining at gaps they regularly use.

Free Bat Inspection

Don’t try to handle bats yourself — they can carry rabies, and guano poses health risks. Our licensed technicians handle it safely and legally.

Frequently Asked Questions

Can you just kill the bats?

No — killing bats is illegal in Pennsylvania and Delaware. Bats are protected under state and federal law. The correct method is exclusion: we install one-way devices that allow bats to exit but not re-enter, then seal the entry points once all bats have left.

When is the best time for bat exclusion?

Bat exclusion should only be performed during two windows: August 1 – October 31, or April 1 – May 14. During summer (mid-May through July), flightless pups are present and exclusion would trap them inside. We will not perform exclusion during the off-limits season.

How do bats get into my house?

Bats can squeeze through gaps as small as 3/8 inch. Common entry points include gaps where the chimney meets siding, loose flashing, open ridge vents, deteriorated soffits, and gaps around utility pipes.

Is bat guano dangerous?

Yes. Bat guano can harbor Histoplasma capsulatum fungus spores, which cause histoplasmosis when inhaled. Large guano accumulations should be remediated by professionals wearing proper respiratory protection. We offer guano clean-up as part of our bat removal service.
