First two minutes
- Get everyone out of the room and close the door. One bat, one room. Do not chase it with a broom or a tennis racket — you risk being bitten and you risk damaging the head, which is what a lab needs for testing.
- Ask who was in that room. Awake adults who are certain they were not touched are in a different situation from a sleeping person, a toddler, or someone who had been drinking.
- If anyone was asleep in that room — stop. Do not let the bat out. You now need the bat.
That third point is the whole reason this page exists, and it is the one most people get wrong.
Why a sleeping person changes everything
A bat bite can be too small to see and too light to wake you. Because of that, public health guidance treats a bat found in a room with a sleeping person, a young child, or someone impaired as a possible exposure, even with no visible bite and no memory of contact. Humane World for Animals summarises the CDC position plainly: a bat found in that situation should be tested.
Testing means the bat cannot be released. If you open a window and it flies off, the exposure question can no longer be answered, and the decision defaults to caution — which usually means the shot series anyway.
Rabies is worth this much care because of one asymmetry. Post-exposure treatment works, and it works well. But as MedlinePlus puts it: “Once the symptoms begin, the disease is usually fatal.” And on timing: “A series of shots can prevent rabies in people exposed to the virus. You need to get them right away.”
So: capture, contain, call. Today, not tomorrow.
Which bat situation is yours
Bats generate more wrong phone calls than any other animal in a house, because two very different problems look identical from the hallway: a single lost bat, and the twenty you can’t see. Route by where the bat is and who was near it, not by how alarming it looks.
One bat loose in a living space, everyone awake and accounted for, nobody touched it. No trade required. Confine it to one room, open one exterior window, turn off the fans, dim the lights, leave and close the door. Fifteen to twenty minutes.
One bat in a room where someone was asleep, or with a young child, or anyone impaired or unable to reliably report a bite. Do not release it. Capture and contain, then two calls in parallel: your doctor or health department for the medical decision, and animal control for collection and testing.
A bat on the floor, on the ground, or crawling rather than flying. Do not handle it, not even with a broom. A grounded bat is disproportionately likely to be sick, and this is the classic way children and pets get exposed. Cover it with a container if you can do so without contact, and call animal control.
A cat or dog caught it, mouthed it, or was playing with it. Same as above, plus your vet, today. Your pet’s vaccination status changes the response substantially, and quarantine rules vary by state.
A dead bat found indoors. Do not bin it if there is any chance a person or pet had contact, or if it was found where someone slept. Gloves, intact, cool, and call the health department.
Bats seen leaving the roofline at dusk, droppings piling under a gap, or a third indoor appearance this month. This is a roost, not a visitor. Bat exclusion company — and expect a conversation about the calendar before a conversation about price.
A bat in the chimney, or repeated bats appearing in the fireplace. Roost, treated as above. Do not cap the chimney until exclusion is confirmed complete.
A bat outdoors — behind a shutter, under a patio umbrella, in a woodpile, hanging under an eave. Nobody. Leave it alone; it will move on. Bats outside your building envelope are not a problem to solve.
The order of calls, and what going out of order costs
- Contain the bat and identify who was in the room. Two minutes, and it determines everything after.
- The medical call — doctor, urgent care, or health department — if anyone was asleep, small, impaired, or bitten. Same day.
- Animal control, to collect the specimen for testing.
- A bat exclusion company, for the building, on whatever timeline the law and the season allow.
Three specific reversals cost real money or real risk:
- Releasing before the medical call. The commonest one, and it is understandable — the bat is frightening and the window is right there. But letting it go destroys the only piece of evidence that can answer the question cheaply. With no bat to test, caution wins and that usually means the full post-exposure series for everyone who might have been exposed.
- Booking exclusion before checking the season. Exclude in June and you seal flightless pups inside your wall. You then pay for the exclusion, the wall opening, the carcass removal, and the deodorising, having started with a problem that would have cost one of those four.
- Capping the chimney or having the roof sealed first. Same failure as above, arrived at by a different route. Roofers and chimney sweeps are not bat people and will not always know to ask.
Who removes bats — and who will turn you down
Wildlife control / bat exclusion companies do the real work. They find the roost, install one-way exit devices, and seal the building. Good ones warranty the seal.
Animal control is usually the right call for one specific thing: collecting a bat for rabies testing after a possible exposure. Many departments handle this or route you to the lab. They will not clear a colony out of your attic, and asking them to is the day most people waste.
Pest control companies are the wrong call unless that specific company does exclusion work. Bats are not exterminated — in most states they legally cannot be. A company that offers to spray or kill bats is telling you it is either unlicensed or willing to break wildlife law on your property, and you are the one who owns the property.
Who else will say no, and why it’s the right answer:
- Roofers and insulation contractors will decline to work in an attic with accumulated guano until it has been remediated. That’s a health call on their part, not an upsell.
- Chimney sweeps and cap installers will decline to cap a flue with bats in it, or should.
- Wildlife rehabilitators take injured and orphaned animals. They do not do building work, and they generally will not take a bat involved in a possible human exposure, because that bat needs a lab rather than rehab.
- A legitimate bat company will refuse to exclude during maternity season. Treat that refusal as a credential. The one that says yes in June is the one to hang up on.
One bat or a colony?
One bat in October that appears once is often a stray that came down a chimney or through an open door. One bat in July that appears three times is a colony in your attic, and the ones you see are the ones that got lost on the way out.
Signs of a roost: a dark greasy stain around a gap in the soffit or fascia, small dark droppings accumulating below an entry point, and a chittering or scratching sound in the walls at dusk. Guano crumbles to powder when dry; mouse droppings do not.
Maternity season is a real constraint
From roughly May through August, bat colonies contain flightless pups. Humane World for Animals is direct about it: “Do not evict bats from your home when dependent young are present (May through August)” and notes that “Many states specifically prohibit excluding bats when they are raising young.”
Exclude during that window and the adults leave, the pups do not, and they die inside your wall cavity. You have then bought yourself weeks of smell, flies, and a wall-opening bill. If a company offers to exclude in June without mentioning any of this, call someone else.
The cleanup nobody quotes for upfront
A long-established roost leaves accumulated guano in the attic. That is a separate line item, it is the one that varies most, and it is why bat quotes range from a couple of hundred dollars to five figures. Get the inspection first and ask specifically whether insulation removal is included.
