A bat is inside your house: what to do right now
Stay calm and close doors
Close interior doors to keep the bat in one room. Keep kids and pets out.
Don't touch it bare-handed
If it lands, never grab it. Bats can carry rabies, and a bite or scratch can be tiny.
Was anyone asleep in the room?
If the bat was in a room with a sleeping person or a child, don't let it go. Keep it contained and call the local health department about rabies testing.
Call or text us
Call or text 973-510-2585. One bat inside often means more in the attic or walls, and we'll find out how it got in.
If no one was asleep in the room and no one touched it, opening a window and turning off the lights often lets a single bat find its way out. Then call us to find the gap it used.
Signs you have bats in your Fair Lawn attic
Bats are rarely seen in daylight. These are the clues they leave:
Guano (droppings)
- Dark pellets that crumble to dust when crushed
- Piles under a beam, ridge or gable end
- A strong ammonia smell
Bat droppings look like mouse droppings but crumble and sparkle from insect parts. They pile up where the colony roosts, often near the peak of the roof.
Stains and small gaps
- Dark, greasy smudges around a gap
- Droppings stuck to siding, windowsills or the deck
- Openings as small as a finger's width
Oils from bats' fur stain the edges of the gaps they squeeze through — under fascia boards, around chimneys, at gable vents and where the roof meets the wall.
Noise and flight
- Scratching or soft squeaks in walls or ceiling at dusk
- Bats leaving the roofline as it gets dark
- A bat showing up indoors
Bats leave to feed on insects just after sunset. Standing outside at dusk and watching the roofline is often the easiest way to see where they come out.
When bats can be removed in New Jersey
Bats are protected wildlife. Exclusion has to follow these dates:
| Dates | Exclusion allowed? | Why |
|---|---|---|
| April 1 – April 30 | Yes | Bats are back from winter and pups haven't been born yet |
| May 1 – July 31 | No | Pups can't fly yet; excluding the mothers would trap the young inside |
| August 1 – October 15 | Yes | Pups can fly and leave with the colony |
| October 16 – March 31 | Only after an acoustic survey shows no bats | Bats may be hibernating inside and can't safely be pushed out in the cold |
During the no-exclusion months we can still inspect, plan the job, clean up and seal openings that bats aren't using, so the house is ready the day exclusion is allowed again.
Bats in fall and winter: what happens now
From mid-October through March, some bats leave for caves and mines, but others — especially big brown bats — can spend the winter right inside an attic or wall. You might hear them less, then suddenly find one in the house on a warm winter day.
That's why New Jersey only allows exclusion in these months after an acoustic survey shows no bats are present. We do acoustic bat surveys ourselves, using a detector that picks up bat calls, to check whether bats are still inside.
- No bats detected: we can seal the house now, before spring.
- Bats detected: we map the entry points, seal the gaps they aren't using, and schedule exclusion for April.
Either way, you'll know exactly where things stand and what happens next.
How bat exclusion works
Inspect top to bottom
A licensed technician checks the roof, fascia, soffits, gable and ridge vents, chimney and every roof-to-wall joint, then the attic for guano and roosting spots.
Seal the extra gaps
Bats have backup doors. All the openings they're not using as the main exit get sealed first.
Install one-way exits
At the main exits we install one-way devices. Bats fly out at night to feed and can't get back in. No traps, no poison.
Close up and check
After the bats are out, the one-way devices come off and those openings are permanently sealed. We check the result.
Bats are not "exterminated." Killing or poisoning bats isn't the answer — and it leaves a smell and a mess in the attic. Exclusion is what works.
Why bats like Fair Lawn homes
Fair Lawn has a lot of mature trees, green space and the Passaic River along the west side of town — good insect-hunting ground for bats. And much of the housing gives them easy places to roost:
- Cape Cods and colonials from the middle of the last century, with gable vents, attic knee walls and aging fascia boards.
- Split-levels and ranches where the roof meets the wall at several levels, leaving joints that open up over time.
- Older homes in and around Radburn, where decades of settling and repairs can leave gaps at chimneys and trim.
- Homes with new roofs or siding that weren't detailed tightly at the ridge and soffits.
Fair Lawn is part of our regular Bergen County area — we're based in Garfield and also serve Elmwood Park, Saddle Brook, Glen Rock and Paramus. Squirrels and raccoons use the same kinds of gaps, so see wildlife exclusion in Fair Lawn if the noise doesn't sound like bats.
Bat guano cleanup, odor control and insulation
A colony that has lived in an attic for a few seasons leaves a lot behind. Guano soaks into insulation, smells, and can grow mold and fungus — including the fungus linked to histoplasmosis, a lung infection people can get from breathing dust from old droppings. Don't sweep it or vacuum it with a household vacuum.
We handle the cleanup ourselves:
- HEPA cleanup of guano and contaminated debris, with protective gear.
- Odor control to treat the smell left by droppings and urine.
- Attic insulation removal and replacement when the old insulation is soaked or packed with guano.
If bats or other animals damaged wood, vents or trim, see wildlife damage repair.

| Height & roof | Single-story, easy access | Two-story or steep roof needing extra ladder work |
| Season | April or August–mid-October | Winter: acoustic survey first, exclusion may wait for spring |
| Cleanup | Light guano, insulation fine | Heavy guano, odor treatment, insulation replacement |

Bat Removal Questions from Fair Lawn
Can you remove bats from my Fair Lawn house in winter?
Sometimes. From October 16 to March 31, New Jersey allows exclusion only after an acoustic survey shows no bats are present. We run the survey ourselves. If no bats are detected, we can seal the house now; if bats are there, we seal what we can and schedule exclusion for April.
Why can't bats be removed in June or July?
Because May 1 through July 31 is when bat pups are born and can't fly yet. Excluding the mothers then would trap the young inside the house, where they'd die. Exclusion reopens August 1, once pups can fly out with the colony.
Do you kill bats?
No. Bats are protected, and killing or poisoning them isn't the right approach — it also leaves dead bats and odor in the attic. We use one-way exclusion so bats leave on their own and can't get back in, then seal the house.
What should I do if I woke up with a bat in my room?
Don't release the bat. Keep it contained in the room if you can do so safely, and call your local health department about rabies testing. Bat bites can be too small to notice, so they treat a bat in a room with a sleeping person as a possible exposure. Then call us.
How do I know if it's bats or mice in the attic?
Bat droppings crumble to dust and sparkle; mouse droppings are hard and don't crumble. Bats are most active right at dusk and you may see them leave the roofline. Scurrying all night or during the day points to mice or squirrels. Text us a photo.
How small a gap can a bat get through?
Very small — openings about the width of a finger, or even less for smaller bats. That's why bat-proofing means sealing every gap along the ridge, soffits, fascia, chimney and vents, not just the one where you saw them leave.
Is bat guano dangerous?
It can be. Old guano can grow a fungus linked to histoplasmosis, a lung infection, and it soaks into insulation and smells. Don't sweep or vacuum it with a household vacuum. We do HEPA cleanup, odor control and insulation replacement ourselves.
How long does bat exclusion take?
The inspection and sealing are usually done over one or more visits, and the one-way devices stay up for several nights so every bat has time to leave. Then those openings are sealed for good. Big colonies or complex roofs can take longer.
Are you licensed for bat removal?
Yes. Silver Bullet Pest Control is licensed by the NJ Division of Fish and Wildlife for wildlife work and holds NJ pesticide License 90568B, with over 15 years of experience.
