Animal Sounds or Nesting in a Chimney
Scratching, chirping, fluttering, odors or nesting material comes from the chimney or appliance.

Do not light a fire or use chemicals to force an animal out. Keep the appliance closed off from the room when this can be done safely.

Conditions a professional may investigate
- A missing, damaged or unsuitable cap
- Bird or mammal nesting activity
