Quick answer: the squirrel is probably still inside

If a roofer or handyman sealed the hole and you still hear scratching, the squirrel was most likely inside when the hole was closed. A trapped squirrel won't starve quietly: it will chew a new way out, often right next to the patch or through the inside of the house, into a ceiling or wall. Don't seal anything else and don't use poison. The fix is to open the right spot with a one-way door so the squirrel can leave on its own, confirm the attic is empty, then seal it for good. Call Silver Bullet Pest Control at 973-510-2585. We answer 24/7.

Why this happens so often

We get this call every week in North Jersey. A homeowner hears noises in the attic, sees a hole in the soffit or roof edge, and calls a roofer because it looks like a roof problem. The roofer does good work: the hole gets a new board, flashing or a patch. But nobody checked whether the squirrel was home. Squirrels leave to feed in the morning and late afternoon and spend a lot of the day and the whole night inside. If the hole is closed while one is in the attic, it's now sealed in.

It isn't the roofer's fault for not being a wildlife company. Getting animals out is a different job, and it has to come first.

Signs the squirrel was sealed inside

  • Scratching or running in the attic or ceiling, mostly around sunrise and late afternoon
  • Fresh chewing marks next to the new patch, on the outside or the inside
  • Chewing sounds in one spot that get louder over a day or two
  • Insulation or wood shavings falling from a ceiling light, vent or attic hatch
  • A squirrel suddenly in the living space, a closet or the basement
  • A few days later, a bad smell in one room (see smell after the hole was sealed)

What we see on these jobs

The three situations behind most of these calls in North Jersey:

Squirrel eating nuts
Squirrels

Squirrels in the Attic or Walls

  • Running and scratching in the morning and evening
  • Chewed fascia, soffits or vents
  • Nesting material in the attic

We get squirrels out with one-way doors and seal the roofline so they can't chew back in. Exclusion, not relocation.

Raccoon on a roof near an opening it could use to get inside
Raccoons

Raccoons in the Attic or Chimney

  • Heavy thumping at night
  • Torn vents, shingles or soffits
  • Droppings and a strong smell

Raccoons tear their way in and do real damage. We remove them from the house and close the opening with heavy-duty materials.

Chipmunks, Skunks & Other Wildlife

  • Burrows along walkways and foundations
  • Animals under porches and sheds
  • Digging in the yard and garden

Ground animals cause foundation and yard problems. We find where they live and block access so they move on.

What not to do

  • Don't seal more holes. Every new patch makes it more likely the squirrel chews into the house instead of out.
  • Don't use poison. A poisoned squirrel dies in the wall or attic, and the smell lasts for weeks.
  • Don't open the ceiling yourself. A scared squirrel inside a living room is harder and more dangerous to deal with.
  • Don't wait it out. Squirrels don't give up. They chew, and they can chew wiring while they do it.

The right order: get them out, then seal

StepWhat happensWhy the order matters
1. InspectFind every opening, which ones are active, and check for babiesSealing an active hole with animals inside is what causes the trouble
2. One-way doorA one-way door goes over the active opening; other gaps are sealedAnimals leave on their own to feed and can't get back in
3. Confirm it's emptyWe check that no more animals are coming and goingOne animal left behind will chew a new hole
4. Seal and repairThe door comes off and the opening is closed with chew-proof materialNow the roof repair is done on an empty attic
5. Clean upDamaged insulation and droppings are dealt withRemoves the smell and nesting material that draws the next animal

This is exclusion, not relocation. We don't trap and move squirrels; they leave through the one-way door and can't get back in.

What about the roofer's patch?

Often the patch itself is fine and only needs a one-way door next to it or through it for a few days. Sometimes the squirrel has already chewed around it, and that part has to be redone with metal behind it. We seal entry points with chew-proof materials and handle wildlife damage repair on fascia, soffits, roof vents and roof edges, so you don't need a second contractor to undo and redo the work. If the animal is a raccoon, read raccoon sealed in the attic; raccoons react differently.

Spring and late summer are the riskiest

Squirrels in New Jersey usually have young in late winter to spring and again in late summer. If the hole is sealed during baby season, the mother is outside and the babies are inside, and she will tear into the roof to reach them. That's why we always check for young before sealing anything.

Simple ways to prevent it

🌳

Trim branches

Keep tree limbs about 6 to 8 feet from the roof so squirrels can't jump on.

πŸ—‘οΈ

Lock the trash

Use cans with tight lids and bungee cords. Raccoons learn trash night fast.

πŸ”©

Cap the chimney

A sturdy chimney cap keeps out raccoons, squirrels and birds.

πŸ”

Check the roofline

Look for chewed soffit corners, loose vents and gaps at roof returns each spring and fall.

Frequently Asked Questions

Will a squirrel die if it's sealed in the attic?

Sometimes, but usually it chews a new way out first, either through the roof or into the house. If it does die inside, the smell can last for weeks.

How do I know the squirrel is still inside?

Noises at sunrise and late afternoon, fresh chewing next to the patch, and debris falling from vents or lights are the usual signs. We can confirm during an inspection.

Should I call the roofer back?

Call a wildlife company first. Once the animals are out, the opening can be sealed properly. We handle both the removal and sealing the entry.

Can I just open the hole again?

It's better to put a one-way door on it so the squirrel can leave but not come back. An open hole just lets it, or another one, back in.

How long does it take to get a sealed-in squirrel out?

Once a one-way door is in place, squirrels usually leave within a few days. We check before the final seal.

Can a trapped squirrel get into my house?

Yes. Trapped squirrels often chew through ceilings, walls or around light fixtures into the living space. See our page on an animal chewed through the ceiling.

Do you relocate squirrels?

No. We use exclusion: one-way doors let squirrels leave on their own, then the entry is sealed.

How fast can you come?

Call 973-510-2585. We answer 24/7 and can send a tech at any hour; arrival depends on your location.
