How do you get rid of bats in Hackensack, NJ?
Bats are removed by exclusion: one-way devices go over the openings they use, the bats fly out at night and can't get back in, and all other gaps are sealed. In New Jersey exclusion is allowed April 1–30 and August 1–October 15, is not allowed May 1–July 31 while pups can't fly, and from October 16 to March 31 is done only after an acoustic survey shows no bats inside. Silver Bullet Pest Control is licensed by the NJ Division of Fish and Wildlife and serves Hackensack from Garfield. Call or text 973-510-2585.
What can be done in each month
Bats are protected in New Jersey, and the state sets when they can be excluded so mothers aren't separated from pups. Here's what that means for you:
| When you call | Exclusion allowed? | What we can do |
|---|---|---|
| April 1 – April 30 | Yes | Inspect, install one-way devices and seal |
| May 1 – July 31 | No — pups can't fly yet | Inspect, plan, seal unused gaps, handle a bat loose inside, and book August |
| August 1 – October 15 | Yes | The main exclusion window: one-way devices, sealing, final close |
| October 16 – March 31 | Only after an acoustic survey shows no bats | Inspect and survey; seal an empty building, or book April if bats are present |
It's November now, so for most Hackensack buildings we inspect, run the acoustic survey and either seal the building or set up the exclusion for April. A single bat flying around your living space can be taken care of any time of year.
A bat inside your house or apartment
Close it in one room
Shut the door, put a towel along the bottom, turn on the light and keep everyone out. In an apartment, close interior doors so it can't reach the hallway.
Think about who was there
If the bat was in a room with a sleeping person or a small child, keep the bat — don't let it go — and call your local health department about rabies testing.
Never use bare hands
Bat teeth are tiny and a bite may not be noticed. Use thick gloves or leave it to us.
Call or text us
973-510-2585. We take care of the bat and look for how it got in — one bat inside often means more in the walls or roof.
If there's any chance of a bite or scratch, call your doctor and the health department right away.
Signs of bats in a building
Bats at sunset
Bats dropping out of one spot at the roof edge, gable, chimney or siding seam for 20–30 minutes after sunset.
Droppings
Dark droppings piled under one spot — on a sill, deck, sidewalk or attic floor. They crumble into shiny specks; mouse droppings don't.
Rub marks
Brownish greasy stains around a small gap where bats squeeze in and out every night.
Sounds and smell
Squeaking or scratching in a wall at dusk, and an ammonia smell near the roost.
Text a photo of the droppings or the spot where you see them leave to 973-510-2585.
Why bats roost in Hackensack
Bats eat flying insects, and the Hackensack River and the wetlands and parks along it produce a lot of them on summer nights. Bats feed over the water and tree lines and then look for a warm, dark, tight space nearby to roost during the day.
Hackensack gives them plenty of choices. Older single-family homes and two-families often have gable vents, wood trim and chimneys where small gaps open up over the years. Larger apartment buildings and commercial buildings have long roof edges, parapet walls, expansion joints and siding seams. A bat only needs a very small opening, so a gap you'd never notice from the street is enough.
Bats return to the same roost year after year, which is why a problem that started with a few bats can grow if the building isn't sealed.
Houses vs. large buildings
| Single-family or two-family | Apartment, office or commercial building | |
|---|---|---|
| Common entry points | Gable vents, chimney flashing, soffit and fascia gaps, top of siding | Roof edges, parapets, expansion joints, rooftop vents, siding seams |
| Where bats roost | Attic, wall cavities, behind shutters | Wall cavities, roof voids, spaces behind exterior panels |
| Access | Ladders | Lifts or roof access, coordinated with the manager |
| Who's affected | One household | Several units — complaints from many tenants |
| Planning | Usually one inspection and a short job | Survey of the whole envelope, work in phases |
Either way we look at the whole building, because bats rarely use only one opening.
How we exclude bats
Inspect
A licensed technician checks the roofline, vents, chimney, trim and attic, and notes every gap a bat could use.
Watch or survey
We confirm where bats are leaving, and outside the open windows an acoustic survey, which we run ourselves, tells us whether any are still inside.
One-way devices and sealing
In a legal window, one-way devices go on the active openings and the other gaps are sealed. Bats leave to feed and can't come back. We never trap or kill bats.
Final close
After the bats are gone, the devices come off and the last openings are sealed.

Renters, landlords and building managers
If you rent: bats in the walls or a bat in your apartment is a building problem. Tell your landlord or super right away, in writing, and include the date and what you saw. If a bat was in the room while someone slept, keep it contained and call the health department first.
If you own or manage the building: bat calls from tenants usually come in waves on summer nights. We can inspect the whole building, explain the legal dates to you and your tenants, and give you a written plan with the openings marked. If the work has to wait for the next window, we can still seal unused gaps and handle any bat that gets inside in the meantime.
For other pests in multi-family buildings, see our apartment building programs, and for the general rules on who handles what, our landlord vs. tenant guide.
Common mistakes with bats
Sealing the hole yourself
Blocking the exit traps bats inside. They die in the walls or find a new way into the living space.
Sprays and mothballs
Repellents don't solve the problem and can make things worse. Exclusion is the method that works.
Sweeping up guano dry
Old droppings can carry fungus spores. Don't stir up dust — after the bats are out, we do the cleanup ourselves with HEPA equipment and protective gear.
Letting a bedroom bat go
If someone was asleep in the room, the bat may need to be tested. Keep it and call the health department.

Bat Questions from Hackensack
Can you remove bats in November?
From October 16 to March 31 bats can only be excluded after an acoustic survey shows none are inside. We can inspect and survey now, then seal the building or set the exclusion for April. A bat loose in your living space can be handled any time.
Why do I have to wait until August?
From May 1 to July 31 young bats can't fly. Sealing the openings then would trap them inside, so New Jersey doesn't allow exclusion during those months.
A bat was in my room while I was asleep. What do I do?
Don't let it go. Keep it closed in a room or container if you can do so safely, and call your doctor and local health department about rabies testing.
How did a bat get into my apartment?
Usually from a roost in the walls or roof void, through gaps around pipes, vents, air conditioners or ceiling fixtures. It's a building problem, so tell your landlord or super.
Do you kill bats?
No. Bats are protected. One-way devices let them leave, then we seal the openings.
Do you work on high-rise and commercial buildings?
Yes. We inspect the roof edges, parapets, joints and vents and coordinate access with the building manager.
Is bat guano dangerous?
Old droppings can carry fungus spores, so don't sweep or vacuum them dry. After the bats are out, we do the HEPA cleanup and odor control ourselves and replace soiled insulation if needed.
Are you licensed for bat work?
Yes. Licensed by the NJ Division of Fish and Wildlife, NJ License 90568B, with over 15 years of experience.
How fast can you get to Hackensack?
We're in Garfield, about 15 minutes away. Same-day visits are often available for a bat inside.
