Why Animals Often Enter Chimneys During Cooler Months

As the temperature drops and cooler temperatures arrive with the changing of seasons, homeowners may find that animals have taken up residence in their chimneys, bringing in nesting or bedding material with them. It’s not uncommon to find animals in the chimney, or even birds, at this time of the year because they seek out the warmth that emanates from your home. To them, it’s quite comfortable in the chimney!

Animals in chimneys are a big problem, not just because they can create unpleasant odors and make a mess with droppings and food, but because they can create an unsafe environment for you and your family. Their activity can damage your chimney, and their presence creates a huge fire hazard. It can also present a very real carbon monoxide poisoning threat, as the debris prevents proper airflow.

Figuring out why and how you end up with animals in the chimney, and knowing what you can do, will allow you to better prepare and prevent any animal damage from occurring. From learning why chimneys attract animals to understanding wildlife prevention and chimney cap installation, you’ll be equipped with knowledge to ensure a safe fireplace season for your family.

Why Chimneys Attract Animals

Chimneys might not seem like an ideal space for an animal or bird, but realistically, they offer a lot to the little critters in our neighborhoods. Chimneys provide both warmth and a windbreak in the cold winter months, making them a great shelter from the elements. Additionally, chimneys also offer some protection from rain, snow, and other predators. 

Animals that do not hibernate over the winter will look for shelter, and a chimney could be just the place they choose if you do not prevent them from entering. Chimneys also mimic the conditions an animal or bird might find in a hollow tree, making them another attractive option because they remind them of natural spaces for nesting and sleeping. Animals in chimneys find the conditions ideal, which is why you can end up finding all kinds of animals in your chimney. 

Common Animals Found in Chimneys

No matter where you live, there are all kinds of animals in chimneys as well as birds, as we near the colder weather months. Chimneys attract small animals like squirrels and other wildlife like raccoons. Birds and bats also might find a chimney attractive. Mice are almost always nesting in chimneys, especially in rural areas near fields.

If you’re concerned there are animals in the chimney, look and listen for common signs you have uninvited guests. Signs an animal may be inside include droppings or scat, feathers or fur, nesting material, or other debris. You may also hear animals or birds making noise as they move about and settle into the nest. Absolutely avoid using your fireplace if you suspect there are animals. You won’t drive an animal out, and you could end up burning them alive if you do have a fire with an animal present.

Potential Problems for Homeowners

While it may seem like a simple nuisance, having animals in the chimney is actually a real problem with the potential for very dangerous conditions that could cause major harm. The repercussions could include starting a fire in your home, carbon monoxide poisoning, property damage, and health and sanitation concerns. Wildlife can carry disease and bacteria that humans should not be exposed to.

Nesting materials can pose fire hazards and block ventilation and airflow, preventing carbon monoxide from venting out of your home. The buildup can be deadly! Wildlife prevention is important, as some animals, such as bats, carry disease. The scat and droppings can also carry bacteria, creating health concerns.

How to Prevent Animals From Entering

An ounce of prevention is worth a pound of cure! If you’re concerned about animals in the chimney or wildlife prevention, you should consider chimney cap installation. You risk animals entering your chimney if you don’t have a chimney cap in place to prevent entry. Chimney caps also help keep rain and snow out, which is great for eliminating damaging moisture.

The durable mesh screen on a chimney cap prevents animals or mice from chewing through it, and it also stops other animals from accessing the chimney.  Animals in the chimney are never a good thing because it is a risky situation for both the animal and the occupants of your home. If any animal takes up residence inside the chimney, it could spell problems for the homeowner as soon as they go to light the first fire of the season.

Keeping nearby tree branches trimmed also removes an access point, making it harder for animals to reach your chimney. Deterring them from making your chimney a home is easier than trying to evict them. Always inspect existing caps or screens to see if they are intact, as over time they can be impacted by the elements.

What to Do if You Suspect an Animal Is Inside

STOP! If you think you might have animals in the chimney,  contact a qualified wildlife company or the chimney sweep for safe removal.

Pay attention to your chimney. Look for debris, scat, or other signs, like fur or feathers, that might indicate an animal has called your chimney home. When you’re inside your home, listen for scratching, rustling, or other noises like chirping that could indicate an animal is inside.

Do not light a fire until you are sure there are no animals in the chimney. Contrary to what some may think, it will not drive the animals away, and it could result in cruelly harming them or worse. Make sure you are on top of your annual maintenance. This should include an annual inspection and cleaning — which will let you know if animals have made their way inside. It will also get them out.

Protect Your Home and Chimney
