Bat & Bird Removal

Pricing depends on the number of entry points, how much of the structure needs sealing, and whether cleanup of droppings or nesting material is involved. A single-entry exclusion with basic sealing tends to run in the low-to-mid hundreds of dollars, while a larger bat colony with multiple gaps along the roofline and attic decontamination costs more because of the added labor and materials.

Yes, since exclusion work doesn't involve poisons or chemical sprays — it's physical: one-way doors, sealing materials, and hand removal of nests. The bigger safety issue is actually before we arrive: dried bat guano can carry histoplasmosis spores, and old bird nests can harbor mites, so we recommend not disturbing droppings or nests yourself and keeping kids and pets away from the attic until it's been cleaned.

We don't recommend it. This is a job for a pest control contractor, since bats and many bird species are protected under wildlife law in the US, Canada, Australia, and the UK, so removing them the wrong way, or at the wrong time of year, can be illegal as well as ineffective. DIY attempts also tend to seal an active entry point while animals are still inside, trapping them and creating a much worse odor and structural problem than the original issue.

Exclusion is usually a single visit to install one-way doors at every confirmed entry point, followed by several nights of monitoring to confirm the space is empty before we seal permanently. Once every gap is sealed with steel mesh or repaired trim, it holds indefinitely, since the animals can't get back through a point that's now closed. If they find a different way in later, that's covered under our guarantee at no extra cost.

Bats tend to announce themselves with scratching or squeaking that starts right around dusk as the colony heads out to feed, along with a sharp ammonia smell and dark, greasy rub marks around a soffit or roofline gap. Birds are usually more obvious — visible nesting material in a vent or chimney cap, and droppings streaking down siding underneath a roofline. Guano piling up in an attic corner is a strong sign of an established colony rather than a single visitor.

Both start with the same principle, humane exclusion instead of poison or traps, but the details differ. Bats require timing around maternity season so flightless pups aren't sealed in or separated from a mother that could still get back in; birds are more often handled through nest removal timed to nesting law and one-way exclusion at re-entry points like vents and eaves. Bird problems also more often involve ongoing deterrents since birds keep attempting to rebuild in a spot they've used before.
