Is Something Living in Your Crawlspace? Here’s How to Tell

Your crawlspace is out of sight, but it shouldn’t be out of mind—especially if you suspect uninvited guests may have moved in. Rodents, raccoons, insects, and even stray cats can make themselves at home beneath your house, often without you realizing it.

Though cute, the little brown mouse often hides in crawlspaces—rarely alone. Early safe extraction and prevention are key.

Here are a few signs that something might be living in your crawlspace:

• Unusual Noises: Scratching, scurrying, or thumping sounds can indicate animals are active beneath your floors.

• Droppings or Odors: The presence of droppings or a persistent musty or foul smell is a clear sign of wildlife or pest activity.

• Damaged Insulation or Ductwork: Animals often chew through insulation, wires, or ducts to make nests or find warmth.

• Entry Points: Look for small holes, loose vent screens, or gaps around your foundation where pests could enter.

• Visible Nests or Tracks: Shredded materials, nesting debris, or tracks in dust or soil suggest creatures are present.

  
  

If you notice any of these signs, it’s important to address the issue promptly. Unwanted crawlspace residents can cause structural damage, contaminate air quality, and invite further infestations. A professional inspection can help identify the source and ensure your home stays safe, clean, and pest-free.
