Squirrels in Chimneys

Are you hearing scratching, thumping, or squeaking sounds from your fireplace? Noticing a foul or musky odor? Are twigs, leaves, or even paper mysteriously in the fireplace?

Chimneys are ideal nesting spots for squirrels. 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.

Do not attempt to use a squirrel repellent.

Save your money! You will have to open the fireplace to apply them. A trapped squirrel cannot climb out. Generally, wildlife repellents are not effective control measures.

How to Get Rid of Squirrels in Chimney

Dropping 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.

 Trustindex verifies that the original source of the review is Google. A possum was able to gain entry into my basement through the dryer vent. I called Critter Control and they responded a few hours later. John came to my residence and quickly found the unwanted critter and removed her. I am extremely happy with the service I received. Critter Control will be installing a dryer vent to prevent future critters from entering my home.

 Trustindex verifies that the original source of the review is Google. Hudson at Critter Control was absolutely fantastic! He came out to remove some critters in our attic for myself and my wife. From start to finish, the experience was professional, friendly, and incredibly easy. Hudson showed up on time, clearly knew what he was doing, and took the time to explain everything instead of just rushing through the job. What really stood out was the attention to detail and the genuine care for getting the problem taken care of the right way. I was very very nervous about the animals in my ceiling and the possibility of bats. He did everything possible to ease my concerns. It’s rare to come across someone who combines great communication, professionalism, and excellent service like Hudson does. If you need pest or wildlife removed or taken care of, I wouldn’t hesitate to recommend Hudson and Critter Control!
