    Common Symptoms

    Scratching, chirping, chattering, or scurrying noises from the chimney or fireplace.
    Unpleasant odors, often from feces, urine, or a dead animal.
    Visibly seeing animals entering or exiting the top of the chimney.
    Twigs, leaves, or nesting debris found in the fireplace hearth.
    Smoke backing up into the house when a fire is lit, indicating a major blockage.
    A noticeable decrease in the fireplace's ability to draft properly.

    Possible Causes

    The most common cause by far is a missing or damaged chimney cap, leaving the flue wide open.
    Animals seeking a warm, dry, and protected place to shelter or nest, particularly in spring and fall.
    Overhanging tree branches that provide easy access for climbing animals like squirrels and raccoons to get onto the roof.
    Wide flue openings that are particularly inviting for larger animals like raccoons.

    Step-by-Step Diagnosis

    1

    Step 1

    Listen carefully at different times of day to identify patterns in the noise (nesting vs. trapped).

    2

    Step 2

    With the damper open and the fireplace cold, use a strong flashlight to look up the flue for obstructions or eyes.

    3

    Step 3

    If it's safe to do so, visually inspect the top of the chimney from the outside for a missing cap, nesting material, or visible animals.

    4

    Step 4

    Attempt to identify the animal by its specific sounds (chirping, chattering, growling) to determine the risk and removal method.

    5

    Step 5

    If you've recently used the fireplace, note any issues with smoke drafting into the room, which signals a critical blockage.

    When to Call a Professional Chimney

    • If you suspect the animal is a raccoon, bat, or anything potentially aggressive.
    • If you hear high-pitched squeaking, which indicates the presence of babies.
    • If there is a strong, foul odor, which almost certainly means the animal is dead.
    • If you cannot safely access your roof to inspect the chimney top or perform a DIY removal.
    • If smoke backs up into your home when you try to use the fireplace.
    • If your attempts to encourage the animal to leave on its own have failed after 24 hours.

    Prevention Tips

    • Install a high-quality, professionally-secured chimney cap made of stainless steel on every flue.
    • Trim tree limbs and branches so they are at least 10 feet away from your chimney.
    • Schedule an annual professional chimney sweep and inspection to catch potential issues early.
    • Keep the area around your home free of garbage or other food sources that might attract wildlife.
