Baby Squirrels & Raccoons in the Attic: NJ Season Guide

In New Jersey, gray squirrels usually have babies from February to April and again from July to September, and raccoons have their kits mostly from April to June. If there are babies in your attic, the mother must not be sealed out: she'll tear the house open to get back to them. The right approach removes the family together and then seals the roofline. Call 973-510-2585 if you hear high-pitched chirping or squeaking.

Baby season calendar

AnimalBabies bornLeave the nest
Gray squirrel (1st litter)February to AprilAbout 10 to 12 weeks later
Gray squirrel (2nd litter)July to SeptemberAbout 10 to 12 weeks later
RaccoonApril to JuneKits start following mom at about 8 to 10 weeks
Big brown batJune to JulyPups fly by late summer

Bats are on a separate schedule. See bat exclusion.

How to tell babies are up there

  • High-pitched chirping, squeaking or chattering from one spot in the ceiling or attic, often when the mother returns.
  • Activity in the same small area every day instead of running across the whole attic.
  • A mother squirrel going in and out of one hole repeatedly during the day.
  • Raccoon kits make a trilling, bird-like chatter, mostly at night.

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 timing changes the plan

A standard exclusion lets animals leave through a one-way door and keeps them out. That works for adults. But babies can't leave on their own, and if the mother is shut out, two bad things happen: the babies die in the attic and cause odor and flies, and the mother chews or rips a new hole trying to get back in, often bigger than the first.

When babies are present, we locate the nest, carefully remove the young and let the mother retrieve them or reunite the family outside, and then complete the exclusion and sealing. With raccoons especially, a mother will move her kits to a new den once she's disturbed, which is why careful planning matters. We're licensed by the NJ Division of Fish and Wildlife and use exclusion, never trap-and-relocate.

What you should and shouldn't do

  • Don't seal the hole or set traps on your own during baby season.
  • Don't handle baby animals. Raccoons can carry roundworm and rabies; even baby squirrels bite.
  • Do note when you hear the noises and where in the ceiling.
  • Do keep pets away from the attic and any hole outside.
  • Do call early. A family in March is a smaller job than repairs in May.

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

When do squirrels have babies in New Jersey?

Usually February to April, with a second litter from July to September.

When do raccoons have babies in New Jersey?

Mostly April to June.

What do baby squirrels sound like in the attic?

High-pitched chirping or squeaking from one spot, often when the mother comes back.

Can I just seal the hole when the mother leaves?

No. The babies would be trapped and the mother would tear a new hole to reach them.

Will a mother raccoon move her babies?

Often, yes, once she's disturbed she'll move the kits to another den, which is part of how we plan removal.

Are baby raccoons dangerous?

Don't handle them. Raccoons can carry rabies and roundworm, and even young ones bite.

Do you remove babies humanely?

Yes. We plan removal so the family stays together, then seal the house. We don't relocate.

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 much damage do nesting squirrels cause?

They shred insulation, chew wood and wiring and leave droppings. Acting early keeps damage smaller.
