Animals use chimneys as shelter because they are dark, sheltered and tall. In Connecticut, chimney swifts, squirrels, raccoons and bats are the usual guests, and each causes blockage, damage or odor.
Signs of Animals
- Scratching, chirping or movement sounds
- Nest debris in the firebox
- Strong, musty or foul odor
- Droppings in or around the fireplace
What to Do
Do not light a fire. Call a certified technician, because some species, such as chimney swifts, are protected by law and must be removed correctly.
Prevention
- Install a stainless steel cap with mesh
- Close the damper when not in use
- Schedule annual cleaning and inspection
Protected Species and Humane Removal
Chimney swifts are protected under federal law, so removing them or their nests during nesting season is restricted. A trained technician can identify the species and recommend a lawful approach. Raccoons and squirrels should be removed humanely, and the chimney should be capped afterward.
