Symptoms

  • Heavy footsteps, thumping, or growling sounds mostly at night
  • Damaged vents, roof edges, or a torn chimney cap
  • Droppings that are larger than rodent droppings, sometimes with visible seeds

Likely causes

  • CommonDamaged or missing chimney cap or roof vent providing entryRaccoons are strong and dexterous enough to tear through weak vent covers or missing caps.
  • CommonAttic or chimney offering a safe denning spot for a mother raising youngSpring is a common time for a female raccoon to seek a sheltered spot to raise kits.
  • PossibleAccessible food source nearby drawing them close to the houseUnsecured trash or pet food outside can attract raccoons that then look for shelter close by.

What to do

  1. Do not attempt to trap or handle a raccoon yourself, since they can be aggressive, especially a mother with young, and can carry rabies or other diseases.
  2. Note the time and pattern of sounds to help a professional assess the situation before arriving.
  3. Avoid sealing any opening you find until a wildlife professional confirms the attic or chimney is clear, since trapping raccoons or kits inside causes worse problems.
  4. Secure outdoor trash cans and remove accessible pet food to reduce what's drawing raccoons close to the house.
  5. Call a licensed wildlife control professional to safely remove the raccoon and any young, often using a one-way exclusion process.
  6. Have the entry point professionally repaired and reinforced with heavy-gauge material once the animals are confirmed gone.
  7. Clean and disinfect the area afterward, since raccoon droppings can pose a health risk and professional cleanup may be recommended.

When to call a pro

Call a licensed wildlife control professional for safe removal and exclusion, and a cleaning service for droppings if advised.
