When can bats legally be excluded?

Most states prohibit bat exclusion from June 1 through August 15 (maternity season), when pups cannot fly. Exclusion during this period would trap young inside. We perform exclusion in fall (August 16–October) and spring (April–May). Timing varies by state.

What if I find a bat inside my home?

Do not touch the bat with bare hands. Confine it to one room, open a window, and call us. If anyone in the home may have been exposed while sleeping (bats can bite without waking people), consult a physician about rabies post-exposure prophylaxis.

Is bat guano really dangerous?

Yes. Bat guano can harbor Histoplasma capsulatum — a fungus that causes histoplasmosis, a serious lung infection. Dried guano becomes airborne when disturbed. Cleaning requires respiratory protection, and large accumulations require professional decontamination.

How many bats can live in a home?

Little brown bat colonies in attics commonly range from 20–200 individuals, though colonies of 1,000+ have been documented. Big brown bats typically form smaller colonies. Even 20 bats can produce significant guano accumulation over a season.

Bat Removal

Licensed bat exclusion — the only legal method for bat removal

Bats are federally protected under the Endangered Species Act and cannot be killed or trapped — they can only be excluded. They are the primary reservoir for rabies in the USA, and their guano (feces) accumulates rapidly and supports the growth of Histoplasma capsulatum fungus, which can cause serious lung disease. Only licensed bat exclusion specialists can legally and safely resolve bat infestations.

Warning Signs of Bat Removal

Bats exiting from gaps in the roofline at dusk

Dark brown staining (guano and urine) on exterior walls below gaps

Strong ammonia odor in the attic (guano accumulation)

Bat droppings — small, dark, crumbly — accumulating below roost

Finding bats inside living spaces (entered through gaps in ceiling fixtures)

Seeing any of these signs? Call us immediately — early treatment prevents the problem from growing and reduces total treatment cost.

Our Bat Removal Treatment Methods

We select the most effective approach based on your specific infestation, property, and family situation.

Exclusion Device Installation

One-way exclusion devices (tubes or netting) installed at all entry points allow bats to exit but not re-enter. This is the only legal method and must be done outside maternity season (June–August in most states).

Full Perimeter Sealing

After confirmed departure (7–10 days after device installation), all entry points are permanently sealed. Bats can enter through a gap as small as 3/8 inch — thorough inspection is critical.

Guano Removal & Decontamination

Professional removal of accumulated bat guano with N95 respiratory protection, followed by antimicrobial fogging to neutralize Histoplasma and eliminate odor.

Rabies Exposure Assessment

If a bat has been found in a living space with sleeping individuals, we provide documentation and recommend rabies post-exposure prophylaxis evaluation with your physician.
