Do Squirrels Hibernate? What They Do All Winter

November 9, 2026 · OcuTrap Team · 6 min read

Tree squirrels do not hibernate. Gray, fox and red squirrels stay active all winter, living off cached nuts and sheltering in leaf nests, tree cavities, and sometimes your attic.

That means a squirrel you see crossing the yard in January is not unusually early or confused. It is following its normal winter routine. The same is true when you hear daytime scratching above the ceiling. Winter weather can make a warm, dry building space especially appealing, so the sound deserves a calm and timely response.

Which squirrels hibernate and which don't?

Tree squirrels stay active throughout winter. They may spend more time sheltered during severe weather, but they continue to emerge and use the food they cached earlier.

Some ground squirrels and chipmunks behave differently. They may become dormant or sleep through much of the winter. This distinction explains why homeowners can still see squirrels moving through trees, across roofs, or near buildings even when other small animals seem to have disappeared for the season.

Where do squirrels spend the winter?

Tree squirrels commonly shelter in leaf nests, also called dreys, and in tree cavities. These locations offer protection from cold and wind while keeping them close to their stored food.

Buildings can offer another option. Attics, soffits, wall voids, and garages can provide the warm, dry shelter a squirrel is seeking. If an opening is available at the roofline or around a soffit, a squirrel may use it instead of remaining outdoors. The result can be scratching overhead, visible damage near an opening, or repeated activity around one part of the roof.

Why do squirrels move into attics in winter?

An attic offers shelter from cold temperatures and wind. It can also provide a protected spot ahead of late winter breeding, which makes winter entry more than a brief weather detour.

Listen for scratching during the day, especially in the early morning or late afternoon. Check for chewed vent covers or gaps in the soffit. These signs can help you narrow down both the animal and its likely entry point. Daytime activity points toward a squirrel, although confirming the animal before acting remains important.

What should you do about a winter attic squirrel?

The goal is to get the squirrel out without trapping it inside, then prevent another entry. Work carefully and keep the response humane.

  • Confirm it is a squirrel: Daytime scratching points in that direction. Identify the animal before choosing a removal method.
  • Find the entry: Look for a soffit gap, damaged vent cover, or another opening associated with the activity.
  • Do not seal it inside: Closing the opening too soon can leave the squirrel trapped in the attic or wall void.
  • Use a one-way door or a live trap: Choose an approach that allows humane removal. Check with your state wildlife agency or local animal control before trapping, relocating, or releasing an animal because rules vary by state and city.
  • Seal and repair once it is out: After confirming the squirrel has left, close the entry and repair the damaged area.

If the entry is difficult to reach, you cannot confidently identify the animal, or you are unsure whether the space is empty, contact a wildlife control professional. A professional assessment is often the most practical choice when roof access or animal identification is uncertain.

When are squirrels most active in winter?

Winter squirrels are often most active around midday on milder days. They are more likely to remain sheltered during the worst weather, then come out when conditions improve.

This pattern can make activity seem inconsistent. A quiet day does not necessarily mean the squirrel has left your attic or moved away from the property. Use confirmed entry signs and direct identification, rather than a short period of silence, to guide your next step.

How can OcuTrap help with a winter squirrel problem?

If a live trap is placed at the roofline or attic entry, checking it can be inconvenient. OcuTrap sends a real-time photo alert at the moment of capture, identifying the animal and confirming that the trap has been triggered. That means you do not have to climb up simply to check an empty trap.

Its cellular connectivity also works where Wi-Fi does not reach, including parts of a roof or property with weak coverage. Remote trap and door control from the app can help you release a non-target animal without another site visit. One app can monitor any number of traps across properties.

Winter squirrels are awake and looking for shelter, so check your roofline now and respond before an attic visit becomes a routine. See how humane live capture and real-time alerts can simplify the process at ocutrap.com.

Frequently Asked Questions

Will an attic squirrel leave on its own during winter?

A quiet period does not confirm that a squirrel has left. Tree squirrels stay active through winter but may remain sheltered during severe weather, then emerge on milder days. Confirm whether the animal is still present before sealing an opening. If you cannot verify that the space is empty, contact a wildlife control professional.

Can I seal a squirrel entry hole as soon as I find it?

Do not seal the opening until you have confirmed the squirrel is out. Closing an attic or soffit gap while the animal remains inside can trap it in the building. A one-way door or humane live trap may be appropriate, followed by sealing and repairing the entry after removal is confirmed.

Do I need permission to relocate a squirrel caught in winter?

Trapping, relocation, and release rules vary by state and city. Before trapping or moving a squirrel, check with your state wildlife agency or local animal control for the requirements that apply where you live. A wildlife control professional can also help when the rules or the safest humane approach are unclear.

Why do I hear attic scratching only on some winter days?

Tree squirrels remain active in winter, but their routine changes with the weather. They often emerge around midday on milder days and remain sheltered during the worst conditions. Intermittent scratching can still indicate an attic squirrel, especially when it occurs during daylight and is paired with a soffit gap or chewed vent cover.
