Bat Infestation Removal
Comprehensive Bat Removal & Control Services
Suspect you have unwanted guests in your attic? Identifying a bat infestation early is key to protecting your home and health.
How to Spot a Bat Infestation
Bats are masters of stealth, but they leave specific clues. A bat infestation is often discovered by sounds or smells before the animals are ever seen.
-
Listen: You may hear scratching, squeaking, or crawling noises coming from your attic, chimney, or wall voids. These sounds are most common around dusk and dawn when bats are waking up or returning to roost.
-
Smell: A key sign is the accumulation of guano (bat droppings). Over time, this creates a strong, unpleasant ammonia odor that can permeate into your living space.
-
Watch: Observe the exterior of your home at twilight (roughly 15 minutes before sunset). Watch for bats “dropping” out of high openings like vents, eaves, or rooflines to gain flight speed.
Advanced Identification Signs
If you aren’t sure if it’s a mouse or a bat, look for these specific indicators used by professionals:
-
Rub Marks: Bats have oily fur. As they squeeze into tiny entry points (often as small as 3/8 of an inch), they leave dark, greasy smudges on your siding or fascia. These often look like dirty fingerprints around cracks.
-
The “Crumble Test”: Bat guano looks similar to mouse droppings, but there is a distinct difference. Mouse droppings are hard, while bat guano is shiny (due to insect wings) and crumbles into dust if pressed with a tool. (Warning: Do not touch with bare hands.)
Health Risks: Why Removal is Essential
Bats are beneficial to the environment, but they are dangerous roommates. Trustworthy health sources, including the CDC, highlight two major risks:
-
Histoplasmosis: This is a respiratory disease caused by a fungus found in nitrogen-rich bat droppings. When dry guano is disturbed (such as during attic cleaning or renovation), microscopic spores become airborne. If inhaled, these can cause severe lung infections. Never sweep or vacuum dry guano without professional protective equipment.
-
Rabies Vector: While most bats are not rabid, they are a primary vector for rabies in the U.S. Because bat teeth are tiny, a bite can go unnoticed. If you find a bat in a room where someone was sleeping, health officials recommend seeking medical advice immediately, even if no bite marks are visible.
The “Blackout Period”: When You CANNOT Remove Bats
Important Legal Warning: Most bat species are federally and state-protected. It is illegal to kill them, and there are strict laws about when you can remove them.
We typically cannot perform exclusions during Maternity Season (generally May through August). During this time, flightless baby bats (pups) are left in the attic while mothers hunt. If you seal the entry points during these months:
-
The mothers cannot return to feed their young.
-
The pups will starve and die inside your walls.
-
This creates a severe secondary pest/odor problem and is considered inhumane and illegal.
Note: If you suspect bats during summer, call us immediately. We can prep the home and seal non-active areas, but full exclusion may need to wait until the pups can fly.
Our Solution: Humane Exclusion
We do not use traps for bats; we use a process called Exclusion.
-
Inspection: We identify all potential entry points, including vents, ridges, and loose flashing.
-
One-Way Doors: We install specialized one-way valves over the active entry holes. These devices allow bats to fly out at night to hunt but physically prevent them from flying back in.
-
Sealing: Once we verify the colony has left (and outside of maternity season), we permanently seal the entry points to prevent re-infestation.
-
Remediation: We offer cleanup services to safely remove guano and sanitize the affected area.
