What a Brown Recluse Looks Like
The brown recluse is a small, light‑to‑medium brown spider with a distinct violin‑shaped marking on its back. It has six eyes arranged in three pairs—unlike most spiders, which have eight. Adults typically measure 1/4 to 1/2 inch in body length.
If you’re unsure whether the spider you found matches these traits, compare symptoms and visuals using the Pest Symptoms Index.
Where Brown Recluses Hide
True to their name, brown recluses prefer dark, undisturbed areas. Common hiding spots include:
- Basements and attics
- Closets and storage boxes
- Behind furniture
- Inside shoes or clothing left on the floor
- Under sinks or in utility rooms

How to Identify a Brown Recluse Bite
Brown recluse bites are rare but can cause serious reactions. Early symptoms include:
- Redness and swelling at the bite site
- Increasing pain over 2–8 hours
- A blister that may turn blue or purple
- Possible necrotic (dead) tissue in severe cases
How to Confirm Brown Recluse Activity
Use these steps to verify whether brown recluses are present in your home:
1. Inspect Undisturbed Areas
Look behind boxes, inside closets, and under furniture for spiders or shed skins.
2. Check for Web Type
Brown recluses build irregular, loose webs close to the ground—not the classic circular webs of other spiders.
3. Use Sticky Traps
Place traps along baseboards and behind furniture to monitor activity.
