When selecting places to construct nests, squirrels typically look for secluded areas off the ground with plenty of cover. The natural location for a squirrel nest is between tree branches or in a hollow tree.

Signs of Squirrels in Chimneys

The top of the chimney provides easy access to warmth and shelter for a squirrel nest. While squirrels rarely infest chimneys themselves, the rodents may nest in metal chimney boxes. If the flue is made of stone or brick, a squirrel can climb down and build a more secure nest. If the flue is made of slick metal, the squirrel can fall and get stuck in the fireplace or on the damper.

Residents may hear chittering, fighting, or scratching at all hours of the day, smell squirrel droppings, and even see the pests running loose inside the home. If you hear loud noises at night, you probably have a raccoon in the chimney.

Squirrel Problems in the Chimney

Squirrels in the chimney are a fire hazard. Squirrels like to build nests in warm and protected areas, and chimneys provide an ideal location. They may bring in twigs, leaves, and other materials to construct their nests, which can block the chimney and disrupt proper airflow. Squirrels may accidentally fall or get stuck inside the chimney flue. Their presence can restrict the flow of smoke and gases, leading to poor ventilation and an increased risk of carbon monoxide buildup in the house.

Squirrels have teeth that continue to grow throughout their lives, so they constantly need to gnaw on hard objects to wear them down. This chewing behavior can damage the structure of the chimney, such as cracking the flue tiles or damaging chimney caps, which can eventually lead to leaking or structural issues.

What NOT to do to Get Squirrel out of Chimney and Fireplace

Do not attempt to “smoke out” squirrels. Opening the fireplace can provide an easy escape hatch for a trapped squirrel. A stuck squirrel cannot climb out and escape the smoke and heat. Nesting materials can catch on fire. Baby squirrels cannot escape the fire.

Do not open the damper and try to catch the squirrel. Squirrels are agile and fast. They can elude a snare pole handled by the most skilled pest professionals.

Save your money; do not try any squirrel repellents. You will have to open the fire place to apply them. A trapped squirrel cannot climb out. And generally, wildlife repellents are not effective control measures.

How to Get Rid of Squirrels in Chimney

chimney cap stop squirrels in chimneyDropping a thick rope down your chimney is one of the easiest ways to get rid of a trapped squirrel. Squirrels are excellent climbers and use the rope as an escape route. Your chimney will need a new chimney cap to prevent future animal infestations.

If the squirrel is not stuck inside the flue, the process is more involved.

A live trap used in conjunction with an excluder is the best way to get rid of squirrels. Once the squirrels are removed, proper exclusion devices like a chimney cap need to be installed. If a female squirrel establishes a nest, baby squirrels will need to be safely moved. That can be tricky if the squirrel nest is at the bottom of the chimney.

BAT POOP CLEAN-UP AND PREVENTION! Bat guano removed from gables. No bats found in attic, so put new screens on all gable vents, as one screen was close to breaking and then bats may have gotten in! Great work in Tulsa!

Squirrels and chipmunks were in our attic. So we called Critter Control to do an inspection. Their representative climbed all over our very steep roof and found several places where squirrels had entered our attic.

Upon inspection of the attic, evidence of bats was also found. The Critter Control team came on time to completely caulk the entire perimeter of the house and create an exit strategy for the squirrels and bats.

Because bat droppings can cause histoplasmosis, this also required total removal and replacement of our attic insulation and sanitizing the space. Not a small job in a 1,300 sq. ft. attic! While Critter Control’s cost was high, our homeowners insurance covered most of it. Everyone representing Critter Control was professional, courteous and timely. I would highly recommend them to anyone who thinks they might have unwelcome guests living in their attic

On recommendations from a nearby pest control company, I called Critter Control for suspicious bat droppings.

Madison came out the same day to do an inspection. She was knowledgeable, thorough, and highly professional. She examined the ‘matter’ that had been scattered on my threshold and thought it was foliage. But she then asked to go up to my attic space where the bats could be roosting. She had to walk up 3 flights of stairs with a heavy ladder. She again spent some time searching all the nooks and crannies and found nothing.

She seemed so interested in her craft, it was truly inspiring to see! She reassured me and is writing up a prevention strategy for my appraisal. She charged me NOTHING!! I am so impressed. We need more Madisons in this world!

We noticed droppings on our brand new deck - we were given their number from our contractor. They came the next day. Brian looked at it and said - yeah, bats!! He then checked every area in our attic and he explained exactly what needed to be done.

He found evidence of a mice infestation, provided a referral and they are helping us as well. Great service, very informative, very professional! We are very satisfied and would recommend them to anyone who has any issues with any critters!
