A chimney that burns ten nights a year spends the other 355 as quiet, sheltered real estate, and north Broward's wildlife has noticed. From spring raccoons to canal-bank roof rats to the occasional honeybee colony, an unprotected flue rarely stays vacant long here. Knowing the local calendar helps you catch tenants early, or better, never host them at all.
From roughly February into May, female raccoons across Broward County hunt for den sites to raise their kits, and an open flue reads to them as a perfect hollow tree: dark, warm, protected from hawks and rain. They descend past the damper area, settle on the smoke shelf, and set up a nursery you will hear before you see. Chittering, scratching, and soft thumps that seem to come from inside the wall above the fireplace are the classic soundtrack, and no wildlife call reaches us more often during a Broward spring.
Two rules if you suspect a raccoon family. First, never light a fire to hurry them along; you risk killing animals stuck in the flue and filling your house with smoke in the process. Second, never close off the flue opening while animals are inside, or the mother will tear at everything trying to return to her kits. The workable path is humane removal, timed and handled so mother and young leave together, followed immediately by capping the flue.
Roof rats are the quiet regulars. They run power lines, seagrape, and fruit trees all over the canal neighborhoods, and an uncapped or gap-topped chimney is a highway ramp into the attic and walls. Unlike raccoons, they rarely announce themselves from the fireplace; you hear them at night, elsewhere in the house, long after the flue let them in. Birds stack spring nests onto the smoke shelf, while South Florida honeybee swarms scouting for cavities will absolutely settle inside a flue.
Each guest causes its own trouble. Nests and food caches block airflow, which turns into smoke problems on your next fire and holds damp material against the flue walls in the meantime. Animal residue produces odors that intensify sharply in humid weather. And an established bee colony packs comb into the flue, a removal situation with its own careful handling. Whatever the species, the pattern is identical: the entry point stayed open, and something eventually took the invitation.
Removal starts with identifying who is actually in there. Sounds, droppings, timing, and a look down the flue usually settle it. Raccoons with young call for patience and humane technique; solo animals can often be encouraged out quickly; nesting birds may be protected in ways that dictate timing; bees require their own specialized approach. Rushing this stage, or improvising with smoke or poisons, reliably makes every version of the problem worse and can be dangerous for your household as well as the animal.
Once the flue is empty, the cleanup matters as much as the eviction. Nesting material, droppings, and food debris come out completely, because they block draft, hold moisture, and feed the odors that make fireplaces smell in August. We also look over the flue itself after any extended occupancy, since claws and nesting activity can disturb mortar joints and liner surfaces. Only after the flue is clear and checked does the final step make sense: closing the door permanently.
A correctly fitted stainless cap with sound mesh ends the cycle for every species at once. It is among the least expensive components on the whole chimney, and in a wildlife-rich, salt-air town it may be the highest-value one. The salt-air part matters: cheap galvanized mesh corrodes and opens gaps within a few seasons here, and a gap is all a roof rat needs. Stainless mesh stays closed. Prefab chimneys get the equivalent protection from a sound, tightly sealed chase cover.
Make the mesh check part of your pre-season routine. From the yard, confirm the cap sits straight and the screening looks intact; after any tropical system, look again, since wind-thrown debris bends mesh and loosens fasteners. If you are hearing anything above the fireplace right now, keep the damper closed, skip the fire, and call us. We handle the removal humanely, clear and check the flue, and cap it so the next season's house hunters keep on moving.

Leave the damper shut, skip lighting anything, and have the flue looked at promptly. Spring scratching in Broward is very often a raccoon mother with kits, which calls for humane, properly timed removal.
If the flue stays open, almost certainly. A good den site gets rediscovered every season. A stainless screened cap or a sealed chase cover is what actually breaks the cycle.
No. Animals can be overcome inside the flue, nesting material can ignite, and blocked airflow can push smoke into your home. Humane removal followed by capping is the safe, lasting route.
