A squirrel stuck in your fireplace is easier to fix than it sounds, as long as you don’t panic and light a fire. The animal fell down the chimney and can’t climb back up the smooth flue liner, so your job is to give it a path out, not chase it. Here’s the whole process.
Why Squirrels End Up in Fireplaces
They don’t climb in on purpose. A chimney looks like a hollow tree, which is exactly where a squirrel wants to nest, so here’s how it usually goes:
- The squirrel climbs onto the roof and checks out the chimney opening.
- It drops inside looking for a nest or to escape a predator.
- It can’t climb back up the smooth metal or glazed tile liner.
- It slides down into the firebox and gets stuck.
Gray squirrels and fox squirrels are the usual culprits, and red squirrels can squeeze into even narrower flues. A trapped squirrel is often only found in the flue, since almost anywhere else in the house it can find its own way out.
What to Do First
The moment you hear scratching behind the fireplace:
- Do not light the fire. Smoke won’t drive it out. It’ll suffocate the animal and leave a rotting carcass in your flue.
- Seal the room. Close the glass doors or tape cardboard over the opening so the squirrel can’t get into the living space.
- Open the damper fully so the squirrel has access to the firebox and a potential way out.
- Listen for more than one. Squeaking or noise from multiple spots can mean a litter, which changes everything.
- Check the chimney cap from outside if you can reach the roof safely. A missing or damaged cap is the likely entry point.
Getting the Squirrel Out, Step by Step
What you’ll need: heavy gloves, cardboard or plywood, duct tape, a big towel or blanket, a flashlight, and a live trap if it comes to that.
- Set up an exit path. Open the doors and windows in the room with the fireplace, and close doors to other rooms so it can’t wander deeper into the house. Clear anything between the fireplace and the nearest outside door.
- Open the damper and cover the opening. With the damper open, tape cardboard or plywood over the fireplace, but leave a 4 to 6 inch gap at the bottom so the squirrel can slip out while the rest of the room stays blocked.
- Wait somewhere else, quietly. A squirrel won’t move while you’re standing there. Give it 30 to 60 minutes of quiet, then check without going in. Most leave within a couple of hours.
- If it won’t leave, drop a rope or cloth down. Tie a knotted rope or a heavy towel to the top of the chimney and let the bottom end hang into the firebox. That gives the squirrel something to climb. Check again after a few hours.
- Use a live trap as a last resort. Bait it with sunflower seeds or peanut butter and set it in the firebox with the damper open. Check every few hours. Before relocating any squirrel, check your local rules, and only release it where it’s legal to do so.
What NOT to Do
These mistakes turn a small problem into a big one.
- Don’t light a fire or use smoke. A dead squirrel in the flue stinks for weeks and can attract flies and other pests, plus you may need a chimney sweep to remove it.
- Don’t use mothballs or ammonia. They’re toxic to you and your pets and don’t deter squirrels.
- Don’t poke at it with a broom. A cornered squirrel will bite, and they carry parasites.
- Don’t block the top of the chimney while the squirrel is still inside, that traps it above the damper.
- Don’t grab it with bare hands. Even a scared squirrel can land a painful bite.
How to Keep Squirrels Out for Good
The only fix that lasts is a chimney cap with 1/4 inch mesh, which blocks animals while letting smoke vent. It’s cheap and installs in about half an hour with basic tools.
- Cap the chimney with galvanized or stainless steel and 1/4 inch hardware cloth mesh.
- Trim tree branches at least 8 feet from the chimney so squirrels can’t jump over.
- Check the cap every year for rust and tears. A damaged cap is as good as no cap.
When to Call a Professional
- It’s been trapped more than a day. Stress and dehydration can kill it.
- You suspect a litter. Squirrels usually raise two litters a year, one in spring and one in late summer. If you hear high-pitched squeaking, there may be babies, and a pro can remove the mother and young together.
- The squirrel has died in the flue. Hire a chimney sweep to remove and sanitize it.
- You can’t safely reach the roof. Steep roofs and multi-story homes are worth paying an insured pro for.

Frequently Asked Questions
A day or two at most without food or water, less in hot or cold weather. That’s why it’s worth acting quickly, for the animal’s sake and yours.
Depends on the flue. Rough clay tile and brick give some grip, but smooth metal liners are nearly impossible to climb. If it’s been in there for hours and hasn’t escaped, it needs help.
Usually not. It’s focused on getting out, so you’ll see scratches and droppings at most. The bigger risk is damage and odor if you wait too long and it dies in the flue.
Yes. A cap with 1/4 inch hardware cloth mesh is the single most reliable fix. It also keeps out rain, leaves, and birds.
Don’t try it yourself. A nursing mother will fight to protect her young and may abandon them if disturbed. Call a licensed wildlife rehabilitator or control operator who can remove the mother and babies together.
The Bottom Line
Getting a squirrel out of your fireplace is mostly patience: open an exit, block the room, and wait quietly. Never light a fire with the animal inside. Then cap the chimney with 1/4 inch mesh so it can’t happen again, half an hour of work that saves you a lot of scratching sounds on quiet nights.
