Critters in the Chimney: A Spring Chimney Guide to Keeping Raccoons, Squirrels, and Birds Out of Your Flue
As the Georgia wildflowers begin to bloom and the humid breeze returns to the Greater Atlanta area, homeowners often think their fireplace duties are over for the year. However, spring is the prime season for a different kind of guest to take up residence in your home: local wildlife.
Ensuring your venting system remains code compliant and free of obstructions is essential for maintaining a home with no potential hazards. When birds, raccoons, or squirrels decide to nest in your flue, they create blockages that can lead to smoke backup or even chimney fires. Our guide will help you understand how to identify a wildlife intrusion and what steps to take to ensure your fireplace remains fully operational for the seasons to come.
If you suspect a furry or feathered visitor has moved in, it is vital to contact a chimney professional for a comprehensive chimney evaluation to clear the way and secure your home.

How Do I Get Animals Out of My Chimney?
The most important rule when dealing with wildlife in your flue is to never, under any circumstances, light a fire to remove them. This is inhumane and often results in a trapped, deceased animal that creates a massive hygiene issue and a terrible odor throughout your home.
To remove animals humanely and effectively, follow these steps:
- Identify the species: Different animals require different removal tactics and are subject to different local Georgia wildlife laws.
- Keep the damper closed: This prevents the animal from entering your actual living space, especially in the case of frantic squirrels or birds.
- Contact a professional: A chimney specialist can determine if the system is fully operational and help coordinate with wildlife removal experts if necessary.
- Install preventative hardware: Once the animal is gone, installing a high-quality cap is the only way to ensure the system stays up to code and animal-free.
Why Atlanta Wildlife Loves Your Chimney
In suburbs like Marietta, Alpharetta, and Decatur, the lush tree canopies provide the perfect habitat for critters. To a mother raccoon your flue looks like a hollowed-out tree—the perfect, predator-proof nursery.
Common Spring Intruders
| Animal | Signs of Presence | Common Entry Time |
| Raccoons | Heavy thumping, crying sounds (like human babies). | Nighttime/Dusk |
| Squirrels | Fast scratching, scampering, clicking noises. | Early Morning/Daylight |
| Birds | Chirping, fluttering, or winged shadows in the firebox. | Daytime |
| Bats | Squeaking, rustling, or dark stains at the chimney top. | Nighttime |
The Dangers of “Uninvited Guests”
While a nest might seem harmless, it presents several risks to your property. A blocked flue is a system with potential hazards that can affect the health of your family.
- Fire Hazards: Nests are made of dried leaves, twigs, and fur—essentially high-grade kindling sitting in your vent.
- Carbon Monoxide: If the flue is blocked, dangerous gases cannot escape the home.
- Disease and Parasites: Raccoons and birds carry mites, fleas, and histoplasmosis, which can enter your air ducts.
- Structural Damage: Animals can claw at the mortar and liners, leading to a system that is no longer up to code.

Keeping the Critters Out: Your Prevention Checklist
To ensure your home remains a fortress against the local fauna, you must be proactive. A fully operational chimney is a sealed chimney.
- Install a Full Coverage Masonry Chimney Cap: This is your ultimate line of defense. It shields the entire masonry crown from water damage while the mesh screen keeps sparks in and wildlife out.
- Check the Spark Arrestor: Ensure the mesh is intact and has not been bent or pried open by a persistent raccoon.
- Trim Overhanging Branches: In North Georgia, squirrels use “tree highways” to jump onto your roof. Keep branches at least 10 feet away from your masonry.
- Annual Maintenance: A yearly professional flue sanitizing and sweep ensures that any old nesting material is removed before it becomes a fire risk.
Real-Life Atlanta Scenarios
Chimney Swifts are federally protected migratory birds that are a common sight (and sound) in historic Atlanta neighborhoods like Inman Park, Grant Park, and Decatur. Unlike many birds, they cannot perch on branches; they must cling to vertical surfaces, making the interior of a masonry chimney their ideal nesting ground.
Because these birds are protected under the Migratory Bird Treaty Act, it is illegal to disturb them or their nests. If they move into your flue, we are required to wait until they migrate south in the fall before any cleaning, restoration, or cap installations can take place.
Sandy Springs Squirrel Blockages
Homeowners in Sandy Springs frequently report scratching sounds or unusual odors emanating from their basement fireplaces. While many assume these are just “noises in the house,” squirrels are notorious for choosing chimney flues as a primary nesting site.
Unlike other animals that might accidentally fall into a chimney, squirrels will deliberately build massive nests on the smoke shelf. This accumulation of dry leaves and debris creates a significant fire hazard and can lead to persistent smells and hygiene issues within the home.
Professional Solutions for a Code Compliant Home
Ensuring your chimney is up to code requires more than just looking up the flue with a flashlight. Our team uses specialized cameras to check for obstructions and nesting materials that might be hidden behind the liner. This ensures that when you go to light that first fire in the autumn, there are no potential hazards waiting for you.
