Raccoon Chimney Invasions in Spring, TX: Why Cold Snaps Drive Them Inside
Short answer: when overnight lows in Spring, TX drop into the 30s, raccoons start treating uncapped chimneys like hollow trees. The flue is dark, dry, sheltered, and sized for a 20-pound animal with hands. Pregnant females especially target chimneys in late winter as denning sites for the litters that arrive in late winter and early spring. Cold snaps are usually the trigger that turns a chimney from “noticed” to “occupied.”
If you have heard scratching or rustling inside the firebox, smelled a heavy musk in the living room, or noticed soot on the hearth that you did not put there, we offer raccoon removal in Spring. Our field technicians have seen these signs repeat across hundreds of local homes since the company was founded in 2015.
Why Raccoons Pick Chimneys
To a raccoon, a brick chimney is functionally the same as a hollow tree. Raccoons evolved to den in cavities, and tree hollows are the preferred natural site. Chimneys check every box that a hollow tree does:
- Vertical walls the raccoon can climb easily with its claws
- Dark interior that mimics a den cavity
- Wind protection on all sides
- Smoke shelf above the damper that creates a flat ledge for nesting
- Dry conditions compared to a tree cavity in wet weather
- Quiet location inside a heated home
The smoke shelf is the part most homeowners do not realize exists. It sits above the damper and below the flue, and it is the perfect platform for a raccoon to settle and raise kits.
Why Cold Snaps Are the Trigger
Raccoons can tolerate cool weather without much trouble, but a sharp drop in overnight temperatures changes the calculus. When lows fall into the 30s, the energy cost of keeping warm in an outdoor den site goes up, and the value of a sheltered indoor site goes up with it. Three things happen at once during the first real cold snap of the season:
- Outdoor den sites become less comfortable as wind exposure and damp ground reduce their value
- Pregnant females begin scouting for the warmest available cavity ahead of the late-winter litters
- Established chimney scouts commit fully after weeks of testing the location during warmer nights
The result is the spike in chimney calls that local crews see every year between Thanksgiving and the first hard cold snap. Mike Garrett, a retired U.S. military veteran, founded The Critter Team in 2015. We’ve worked this area since the beginning and our field crews handle every job in-house from inspection through warranty-backed exclusion.
What Chimney Occupation Sounds and Looks Like
Raccoons in chimneys are noisier than most homeowners expect:
- Heavy thumps and rolling sounds from inside the firebox or above the damper
- Scratching on the smoke shelf as the animal moves around
- Chittering and growling from kits, especially after they are old enough to vocalize
- Heavy musk odor in the living room, strongest near the fireplace
- Soot on the hearth kicked down from the smoke shelf
- Movement on the roof at dusk and dawn around the chimney top
Some homeowners mistake the noise for a person walking around upstairs, especially when the raccoon shifts position on the smoke shelf. Raccoons weigh 15 to 25 pounds and they sound like it.
Important: Never start a fire to drive a raccoon out of a chimney. Adults may climb to escape, but kits cannot, and they die in the flue. The result is a much worse problem than the original occupation. Raccoons in Texas can also carry rabies. Do not reach into the firebox or open the damper without professional help.
The Kit Timeline Matters
Raccoon breeding peaks in winter through March, which means most chimney occupations between winter and April involve a pregnant female or a litter on the way. Removing a female without addressing the kits leaves the young trapped on the smoke shelf. Removing only the kits leaves the female desperate and aggressive. The right approach handles both.
The CDC tracks rabies in raccoons as one of the most common wildlife rabies vectors in the United States, and Texas is one of the states with active monitoring. This is one of the reasons hand removal of kits is left to trained crews with the right equipment.
How Raccoons Get In and How to Stop Them
An open chimney top is an open invitation. The fix is simple in concept and reliable when done right:
- Stainless steel chimney cap with a spark arrestor screen, secured to the flue tile or top course of brick
- Animal guard on prefab metal chimneys that do not accept a standard cap
- Repair of cracked crown mortar that creates secondary entry points
- Trim limbs back at least three feet from the chimney to remove climbing access
Cheap mesh covers and DIY screens that the homeowner secures with hose clamps do not last. A 20-pound raccoon will work them loose in a single night. The proper cap is heavy gauge stainless and is secured at the structure, not just resting on top.
What a Real Chimney Removal Job Looks Like
We handle raccoon chimney work as a complete sequence:
- Inspection. Our crew checks the chimney from the roof and from the firebox, identifies the animal and any kits, and documents the entry point.
- Humane removal. We use live trapping at the chimney top or hand removal of kits from the smoke shelf. We reunite females with their kits whenever possible. No poison and no kill methods.
- Cap installation. We install a stainless steel chimney cap with spark arrestor screen, sized to the flue and properly secured.
- Decontamination. We clean and sanitize the smoke shelf, and remove contaminated material.
- Written warranty. We offer one-year and three-year warranty options on the exclusion work.
We run all of this in-house with our own certified technicians. No subcontractors. The same crew that inspects the attic also handles the trapping, fabricates the metal on-site, and completes the cleanup.

Frequently Asked Questions
How do I know if a raccoon is actually in my chimney?
Listen for heavy thumps, scratching, or rolling sounds from inside the firebox or above the damper. A heavy musk odor in the living room near the fireplace is another reliable indicator. Soot or debris on the hearth that you did not put there usually means something is moving on the smoke shelf above the damper. Raccoons are loud enough that homeowners often mistake the noise for a person upstairs.
Can I just light a fire to drive the raccoon out?
No. This is the single most common mistake homeowners make. Adult raccoons may climb to escape, but kits cannot, and they die on the smoke shelf. The result is a decomposition problem inside the flue that is far worse than the original occupation. Smoke also drives panicked animals into the living space if the damper is open. Never start a fire if you suspect a raccoon is in the chimney.
Why do raccoons pick chimneys instead of attics?
Some pick attics, but chimneys are functionally identical to hollow trees, which are the preferred natural den site. Vertical walls, dark interior, wind protection, and the flat smoke shelf above the damper all match what raccoons evolved to use. Pregnant females especially target chimneys in late winter because the cavity stays warm and dry through the litter season.
Will a screen or mesh cover from the hardware store work?
Not for long. Cheap mesh covers and DIY screens do not stand up to a 20-pound raccoon. The animal works them loose in a single night. The proper fix is a stainless steel cap with a spark arrestor screen, heavy enough to resist tampering and secured to the flue tile or top course of brick. Properly installed caps also keep birds, squirrels, and rain out of the flue.
How long does a chimney removal job take?
For a single adult raccoon with no kits, removal and cap installation can usually be completed in one or two visits. If kits are present, the timeline depends on the age of the young, since the goal is to keep the family together and get them out alive. Decontamination of the smoke shelf adds another visit. The written warranty on the cap installation starts the day the work is finished.
