Animals Commonly Found in Chimneys
If you're hearing scratching, chirping, or rustling sounds from your fireplace — or noticing a foul odor coming from the flue — there's a good chance an animal has taken up residence in your chimney. In the northwest Chicago suburbs, the most common culprits are raccoons (especially mothers with young in spring), squirrels, birds (particularly chimney swifts), and occasionally bats. GEM Chimney & Duct provides humane animal removal, complete nest and debris cleanout, flue sanitizing, and chimney cap installation to prevent re-entry — serving Wheeling, IL and the surrounding communities in Cook and Lake counties.
Why a Blocked Flue Is Dangerous
A nest or animal carcass inside your flue is more than an unpleasant smell. Nesting material — dry leaves, twigs, feathers, and fur — is highly flammable and can ignite from a single spark. A blocked flue also prevents combustion gases from venting properly, which can push carbon monoxide back into your living space. This is a silent, odorless danger that can be fatal. If you suspect a blocked flue, do not use the fireplace until the obstruction has been removed and the flue has been inspected.
Common Chimney Animals in the Northwest Suburbs
Each species requires a different removal approach. GEM inspects first to identify the animal before any work begins.
Raccoons
Raccoons are strong enough to push past damaged or missing caps. Females commonly den inside chimneys in spring to raise young. Removal requires care — a mother with kits cannot simply be chased out.
Squirrels
Squirrels enter through gaps around the cap or damaged flashing. They build nests quickly and can chew through damper components. Scratching sounds during the day are a common sign.
Chimney Swifts
Small, fast-flying birds that nest inside masonry chimneys. Federally protected — see the legal note below. Chirping sounds in summer are the most common indicator.
Bats
Bats roost in chimneys and attic spaces. They enter through very small gaps. Removal must comply with state wildlife regulations — we inspect and advise on the correct approach.
Important Legal Note: Chimney Swifts Are Federally Protected
Chimney swifts are protected under the Migratory Bird Treaty Act. It is illegal to disturb, remove, or destroy an active chimney swift nest while eggs or chicks are present. If chimney swifts have nested in your flue, the nest must remain undisturbed until the birds have fledged and left on their own — typically by late summer. GEM will inspect your chimney, confirm whether an active nest is present, and advise you on the correct timing for cleanout and cap installation. We will never perform work that violates federal wildlife law.
Our Animal Removal Process
Camera Inspection
We run a camera through the flue to identify the animal, assess the extent of nesting material, and check for any structural damage caused by the intrusion. This determines the correct removal approach before any work begins.
Humane Removal or Wildlife Coordination
Depending on the species and situation, we remove the animal humanely or coordinate with a licensed wildlife control professional when required by law (e.g., raccoons with young, bats). We never use methods that harm the animal unnecessarily.
Full Nest and Debris Cleanout
All nesting material, droppings, feathers, and debris are removed from the flue. This is critical — nesting material is a fire hazard and a source of odor and bacteria.
Sanitizing and Deodorizing
The flue is treated to neutralize odors and sanitize surfaces contaminated by animal waste. This step is especially important after raccoon or bat intrusions.
Chimney Sweep
After cleanout, we perform a full chimney sweep to remove any remaining debris and confirm the flue is clear and safe to use.
Chimney Cap Installation
We strongly recommend installing or replacing the chimney cap with an animal-exclusion screen to prevent re-entry. This is the only permanent solution.
The Only Permanent Solution: Chimney Cap with Animal Screen
The single most effective way to prevent animals from entering your chimney is a properly fitted chimney cap with an animal-exclusion screen. A standard chimney cap keeps rain out; an animal-screen cap adds a mesh barrier that blocks birds, squirrels, raccoons, and bats while still allowing combustion gases to vent freely. After every animal removal job, GEM recommends installing or replacing the chimney cap to prevent the same problem from recurring. Many homeowners in the northwest Chicago suburbs discover they never had a cap to begin with — or that the original cap was damaged or missing.
