Signs You Have Bats
Bats are quiet tenants. Most homeowners live with a colony for months before anything gives it away. If you’re searching for signs of bats in your home, here are the signs to check tonight:
- Scratching or fluttering in the attic or walls, loudest at dusk and dawn
- Droppings (guano) on the deck, the exterior walls, or the attic insulation, dark, crumbly, and glittering with insect wing parts
- A sharp ammonia smell building up on the top floor of your home
- Dark, greasy staining around a gap, vent, or roofline where bats squeeze through
- Bats circling your roofline at sunset are the clearest sign of an active bat roost
- A bat inside your living space, usually one that got lost on its way out
Bats don’t chew their way in. They take advantage of existing openings and require very little: an opening about 1¼ inches by ¼ inch is sufficient. We find them at soffit-to-wall intersections, chimney flashing, ridge caps, gable vents, and loose fascia.
Humane Isn't a Word. It's a Method.
Every wildlife company in London claims “humane.” Here’s what ours means in practice.
- We don’t trap or relocate. A bat taken from its roost and released elsewhere is very likely to die. Relocation isn’t the kind option; it’s the one that looks kind.
- We don’t poison. The bats die inside your walls, and then you’re paying someone to remove the remains.
- We don’t seal a roost we haven’t emptied. Close the entry without a one-way valve, and you’ve sealed a living colony into your ceiling. Every gap we close, we close only after the bats are out.
And we’ll tell you when to wait.
Bat pups can’t fly for the first several weeks of their lives. If your colony has flightless young, there’s no humane way to evict the adults; the pups starve where they are. Ontario’s bats are also legally protected, and several species, including Little Brown Myotis, Northern Myotis, and Tri-coloured Bat, are endangered, so this isn’t only an ethical question.
So during those weeks, here’s what we do instead of doing nothing:
- Inspect and quote — every entry point identified in writing, free
- Seal the secondary gaps — every opening they could use while the active entry stays open
- Book your exclusion for the moment the pups are airborne
- Evict and seal — permanently, guaranteed
Waiting costs us the job that month. That’s the part of humane bat removal that appears on our invoice instead of our marketing. When it comes to bat removal in London, Ontario, we handle the entire job under one roof — no subcontractors, no half-finished work.

How Humane Bat Exclusion Works
There’s no trapping and no relocation in bat work. The only method that works is exclusion: let them out, don’t let them back in.
1. Full inspection
We examine the roofline, soffits, fascia, chimney, vents, and the interior of the attic. Bats rarely use one entry point, and the active one is usually not the obvious one.
2. Species and colony assessment
Identifying the species tells us the legal requirements and the timing. Counting the colony at dusk tells us the scale. A professional bat pest removal service doesn’t quote a job it hasn’t measured.
3. One-way bat valves
This is where most failed jobs fail. A bat valve is nothing like a raccoon door; bats drop downward to take flight, so the geometry is entirely different. We install valves purpose-built for bats at each active entry. Bats leave to feed at night. They can’t get back in.
4. Full exterior seal
Every other vulnerable gap in the home is sealed with materials bats can’t squeeze through, while the valve remains open as the only exit.
5. Valve removal and final seal
Once the colony is confirmed out, the valves come off, and the last openings are permanently sealed.
6. Cleanup and restoration
Guano removed, space sanitized, contaminated insulation replaced.
That sequence is what humane bat removal services mean in practice, and skipping any step is why bats return. Our professional bat pest removal service includes a Lifetime Guarantee on the seal.
Guano Cleanup & Attic Restoration
Getting the bats out is half the job. A colony leaves behind years of guano and urine, which soak into the insulation and drywall.
Bat guano can harbour histoplasmosis, a respiratory infection caused by a fungus that grows in droppings and becomes airborne when the guano is disturbed. This is not a shop-vac and dust-mask job.
Every bat removal in London we complete includes:
- Guano removal under proper containment and respiratory protection
- Attic sanitization to neutralize bacteria and odour
- Insulation removal and replacement, restoring the R-value the contamination destroyed
- Odour treatment, so the pheromone trail doesn’t advertise your attic to the next colony
That last point is often skipped. An untreated roost remains attractive to bats for years, which is how a “solved” bat problem returns with a different colony.
One Contractor. The Whole Job.
Some companies evict the bats and hand you a list of other contractors to clean up the mess. You end up managing three trades to fix one problem.

Frequently Asked Questions
How much does bat removal cost?
There’s no flat rate, and any company quoting one over the phone hasn’t seen your roof. Cost depends on how many entry points your home has, how high and how accessible they are, the size of the colony, and whether guano cleanup and insulation replacement are needed. A two-storey home with a compromised ridge vent is a different job than a bungalow with one gable gap. We inspect and quote free, in writing, with no obligation.
Who do you call for bat removal?
Not a general pest-control company; bats are not pests. They are a protected species, and the work is legally restricted. You need a wildlife company that can perform exclusion, knows the maternity season, and can clean up afterwards. If you’re in London searching for humane bat removal near me or bat control near me, give us a call at 519-282-8976. For effective bat control in London, Ontario, you want a licensed wildlife company that removes the colony humanely and seals the entry points for good — not a pest service that treats bats like an infestation. We’ll tell you straight up what your home needs, whether that’s “wait until August” or something else.
How do I know if I have bats or mice in my attic?
The droppings tell you. Mouse droppings are small, hard, and uniform. Bat guano is larger, crumbles to dust when pressed, and glitters with undigested insect wings. Sound helps too: mice are active all night and scratch through walls at floor level, while bats are loudest at dusk and dawn and are concentrated high, at the roofline or the top of the wall cavity. And mice chew their way in. Bats don’t. If you’ve been searching “bat pest control near me” and aren’t sure what you’re dealing with, an inspection is what you need.
Is it illegal to remove bats from your house?
You’re allowed to have bats removed from your home, but the how and when are regulated. Several Ontario bat species are endangered and protected under the Endangered Species Act, and sealing a colony in during maternity season kills flightless pups. That’s where humane bat exclusion stops being a preference and becomes a legal requirement. Doing it wrong can expose you to liability, not just a dead colony in your ceiling.
Can bats be removed during winter?
Usually not by exclusion. Big Brown Bats, the species found in most London homes, overwinter inside the structure. In deep cold, they aren’t flying out, so a one-way valve strands them inside. The practical windows are late spring before pups arrive, and early fall once they’re flying. Winter is the right time to book a bat removal inspection in London, so the work is scheduled as soon as conditions allow.
Do electronic bat removal devices work?
No. Ultrasonic repellers, sonic deterrents, and plug-in devices don’t clear a roost; there’s no credible evidence they do, and colonies habituate to them quickly. Mothballs and bright lights don’t work either. Real bat control in London, Ontario, comes down to one thing: getting every bat out and sealing the home so none can return.
