Signs of Squirrels in the Attic

The clearest signs of squirrels in the attic are scratching and running in the early morning and late afternoon, chewed holes at soffit corners or vents, squirrels going on and off the roof, shredded insulation and nests, and small droppings in the attic. If you see these, have the roofline inspected before you seal anything. Call Silver Bullet Pest Control at 973-510-2585.

The signs, inside and out

Inside:

  • Scratching, running or a rolling sound (like a nut) in the ceiling, mostly at sunrise and late afternoon
  • Noise that stops at night (night noise is more often raccoons, mice or rats)
  • Shredded insulation, leaves, twigs or paper in the attic
  • Droppings, slightly larger than rat droppings, often in piles
  • Water stains on the ceiling from urine
  • Lights flickering or outlets dead if wires have been chewed

Outside:

  • A round chewed hole at a soffit corner, roof return or gable vent
  • Chewed vinyl, wood shavings or nest material in the gutter below
  • Squirrels running along the gutters or jumping from trees to the roof
  • Stains around a hole where squirrels rub going in and out

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.

Why not to wait

Squirrels chew constantly to keep their teeth worn down. In an attic, that means wiring, wood and ductwork. They compress and contaminate insulation, and a pair of squirrels in February can mean a litter of babies by March. The longer they stay, the more damage and the more likely they are to chew a second hole.

What the fix looks like

We inspect the whole roofline, check for babies, seal every secondary gap, install a one-way door on the main hole, and seal it permanently once the squirrels are out. See how one-way doors work and squirrel proofing.

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

How do I know if I have squirrels in my attic?

Scratching in the early morning and late afternoon, chewed holes at the roofline and squirrels on the roof are the main signs.

What time of day are squirrels active in attics?

Mostly early morning and late afternoon; they sleep at night.

What do squirrel droppings look like?

Small, rounded pellets slightly larger than rat droppings, often in piles.

Can squirrels damage wiring?

Yes. Chewed wiring in attics is a known fire risk.

Do squirrels leave the attic in winter?

No. Squirrels don't hibernate; they stay active and use attics as winter shelter.

How many squirrels are usually in an attic?

Often a pair or a mother and her litter of two to four babies.

Can squirrels chew electrical wires?

Yes. Squirrels gnaw constantly, and chewed wiring in an attic is a real fire risk, which is one reason to act quickly.

How much does it cost to get squirrels or raccoons out?

It depends on how many entry points there are, the roof height and whether repairs are needed. Estimates are free: call or text 973-510-2585.

Do you clean up the attic after wildlife?

We can advise on damaged insulation and droppings cleanup after the animals are out and the house is sealed.

Are you licensed for wildlife in New Jersey?

Yes. Silver Bullet Pest Control is licensed by the NJ Division of Fish and Wildlife and holds NJ Pesticide License 90568B.

What if a squirrel or raccoon gets into my living room?

Close interior doors to keep it in one room, open an outside door or window in that room if it's safe, keep pets away and call 973-510-2585. We answer 24/7.

Can I see the entry points you found?

Yes. We show you the openings, and photos when possible, so you know exactly what was sealed.

How do you get squirrels out?

With one-way doors after sealing every other gap, then permanent sealing.
