Short answer

Stop using any fireplace, dryer, exhaust fan, furnace, or other equipment connected to the affected space, and keep people and pets away. Contact local animal control or a humane wildlife-control professional; if there is fire, smoke, a gas odor, sparking, or a carbon monoxide alarm, leave the building and call 911 from outside.

Do not do these things

Do not light a fire or use smoke, fumes, poison, water, or glue traps to force the animal out.
Do not operate an appliance, fan, fireplace, or heating system connected to the affected chimney, duct, or vent.
Do not cap, seal, tape over, or permanently block an opening while an animal or dependent young may remain inside.
Do not reach into a dark cavity or handle wildlife with bare hands.
Do not chase an animal that enters a room.
Do not let children or pets approach the animal or opening.
Do not climb onto the roof, cut into a wall or ceiling, or dismantle an appliance unless you are qualified to do so.
Do not release or discard a bat that may have contacted a person or pet before speaking with animal control or a public health professional.

What to do now

Check for an immediate building hazard. If you see fire or smoke, smell gas, notice sparks or a burning electrical odor, or hear a carbon monoxide alarm, move everyone outside and call 911 from a safe location.
If there is no immediate hazard, stop the connected equipment using its normal controls. This may include a fireplace, wood stove, dryer, range hood, bathroom fan, furnace, or HVAC system. Do not take the equipment apart.
Keep children and pets out of the affected room. If the animal enters a living space, close interior doors to contain it, keep your distance, and avoid chasing or touching it.
From a safe indoor position, note where the sound is strongest, when it occurs, and whether you can see an animal, nest, damaged vent cover, droppings, or entry opening. A photo or short recording may help a professional assess the situation.
Contact local animal control or a humane wildlife-control professional and explain whether the animal is in a chimney, appliance vent, air duct, wall, or ceiling. If the animal appears injured or orphaned, ask animal control or a wildlife rehabilitator what to do.
For a chimney or appliance vent, keep the connected system unused. Ask whether a chimney professional, HVAC technician, dryer-vent technician, or appliance technician should inspect and clear the passage after the animal and nesting material are removed.
If the animal may be a bat, keep people and pets out of the room and contact animal control or your local or state health department. Mention any direct contact and whether a bat was found with a sleeping person, unattended child, or anyone unable to rule out contact.
If anyone was bitten or scratched by wildlife, wash the wound with soap and water for 15 minutes and contact a healthcare or public health professional promptly. If a pet had contact with wildlife, separate the animals and contact a veterinarian.
If you rent, notify the landlord or property manager promptly after dealing with any immediate danger. State which room, chimney, vent, or appliance is affected and that wildlife or building access may be needed.
Before an opening is sealed, ask the professional to confirm that all animals and dependent young are out. Most migratory bird nests containing eggs or chicks are federally protected, and other wildlife rules may vary by state or locality.

What can wait

Permanent chimney caps, vent screens, wall repairs, odor treatment, insulation replacement, insurance questions, and long-term wildlife-proofing can wait. You do not need to identify the exact species or decide whether a wall or ceiling should be opened before stopping connected equipment and contacting appropriate help.

Important reassurance

Sounds can travel through chimneys, ducts, walls, and ceiling spaces, so the animal may not be directly behind the place where it sounds loudest. Keeping the area quiet and connected equipment off reduces immediate risk while a professional locates the animal.

Scope note

This guide covers immediate safety, containment, and contact steps only. Removal, structural access, cleanup, repairs, and future exclusion may require wildlife, chimney, HVAC, building, veterinary, or public health specialists.

Important note

This is general information, not veterinary, medical, legal, fire-safety, wildlife-control, or building advice. Wildlife laws and available services vary by state and locality. Follow instructions from emergency services, public health officials, animal control, wildlife rehabilitators, and qualified building professionals.
