Noises In my attic/walls?

1. Identify the Type of Noise

• Scratching or Scrabbling: This could indicate small animals like mice, rats, or squirrels.
• Thumping or Bumping: Larger animals like raccoons or opossums may be the cause, especially if the noises are loud.
• Chirping or Squeaking: Birds or bats might be present, particularly if the noise is softer and continuous.
• Rattling or Rustling: Could suggest the presence of snakes or insects, especially if accompanied by hissing or buzzing.

2. Check for Physical Evidence

• Droppings: Different animals leave distinctive droppings. Mice and rats leave small, pellet-like droppings, while raccoons leave larger ones. Bird droppings may also be present.
• Nests or Bedding Material: Look for nests made of shredded paper, insulation, or other materials. Birds, squirrels, and rodents often create these.
• Damage to Insulation or Wires: Chewed wires or damaged insulation can indicate rodents. Be cautious, as damaged wires can be a fire hazard.

3. Inspect Common Entry Points

• Vents and Chimneys: Birds and bats often enter through roof vents or chimneys. Ensure these are securely covered.
• Holes and Gaps: Check for holes or gaps in the roof, eaves, and walls. Rodents and other small animals can squeeze through surprisingly small openings.
• Eaves and Soffits: Squirrels and raccoons may enter through gaps in eaves or soffits.

4. Differentiate from Other Potential Causes

• Insects: Large insect infestations can sometimes cause noise, especially if they're building nests or colonies.
• Structural Issues: Sometimes, noises can be due to settling or expanding structures, particularly in older homes.
