How We Remove Bat Colonies

Our bat removal process begins with a thorough inspection of your property to locate every active entry and exit point the colony is using. Bats can enter through gaps as small as 3/8 of an inch — so our inspections are methodical and complete.

Once all entry points are documented, we install custom one-way exclusion devices at each active opening. These devices allow bats to exit the structure normally — but prevent them from re-entering. The bats leave at dusk, find they cannot return, and relocate to natural roost sites over the following days.

After the colony has fully vacated (typically 5–10 days), the exclusion devices are removed and the openings are permanently sealed. The result: a completely bat-free structure with no dead bats, no poisons, and no violations of Idaho or federal wildlife law.

• Complete property inspection
• Custom one-way exclusion devices at all active entry points
• No trapping, no poison, no harm to bats
• Full compliance with Idaho Fish & Game regulations
• Works on all Idaho bat species
• Residential & commercial

Important: Exclusion Timing in Idaho

Idaho bat exclusion work must be timed to comply with wildlife protection regulations:

• Spring (March–May): Ideal exclusion window before maternity season
• Summer (June–August): No exclusion during maternity season when flightless pups are present — this is both illegal and inhumane
• Late Summer–Fall (Aug 15–Oct): Second ideal window after pups become flightless
• Winter: Bats in hibernation — exclusion possible in some cases

We assess your situation and schedule exclusion work at the appropriate time. Call us any time to discuss your specific circumstances: 801-633-8007

Why Guano Cleanup Is Critical

Accumulated bat guano is not just an aesthetic problem — it poses genuine health risks. Bat droppings can harbor Histoplasma capsulatum, a fungal pathogen that causes histoplasmosis when its spores are inhaled. The risk is highest when dried guano is disturbed during attic work, renovation, or HVAC activities that circulate air through contaminated spaces.

Do not disturb bat guano yourself. Proper cleanup requires full PPE, an N-100 respirator, and EPA-registered decontaminants. Our crews are trained and equipped to handle all levels of guano accumulation safely.

Our Cleanup Process

1. Assessment: We evaluate the extent of contamination and determine whether insulation replacement is needed.
2. Safe removal: Guano is carefully removed using HEPA-filtered vacuum equipment and manual removal as needed, with PPE-equipped technicians throughout.
3. Decontamination: We apply EPA-registered enzyme-based decontaminants to neutralize biological pathogens, fungal spores, and residual organic material.
4. Odor neutralization: Professional odor treatment eliminates the ammonia-based odors that accumulate from bat urine and guano.
5. Insulation replacement: When contamination has compromised attic insulation, we safely remove the affected material and replace it with fresh insulation to restore proper thermal performance.

Signs of Significant Guano Accumulation

• Strong ammonia smell from attic, especially in warm weather
• Dark staining on attic floor joists and insulation
• Insulation appears compacted or matted down in areas under colony roost points
• HVAC delivering unpleasant odor when running
• Colony in place for multiple seasons — accumulation compounds rapidly

Health Conditions Associated with Bat Guano

• Histoplasmosis — lung infection from Histoplasma capsulatum spores in guano
• Rabies exposure — from bats that have died in the structure
• Bat bugs — parasitic insects related to bed bugs that infest bat roost sites

If you have reason to believe guano has been disturbed or you have experienced respiratory symptoms after attic exposure, consult a physician.
