Most people recognize brown recluse spiders by the tiny violin-shaped markings on their backs. However, these spiders are so small that the dark brown marking may be hard to see. Brown recluse spiders measure about ½ an inch in length, most of that being their long, thin legs.
To identify them, focus on their overall shape and texture. They have smooth, velvety bodies covered in fine hairs—not some other spiders' fuzzy, hairy look. The front half of their bodies is oval-shaped and features two small, leg-like appendages (palps) and the violin marking.
The back half is pill-shaped and completely unmarked.
Brown recluse spiders are predators that rely on their fangs and venom to catch prey. Their diet mainly consists of soft-bodied insects, which they hunt at night by ambushing them.
One thing to keep in mind is that these spiders are incredibly resilient. Studies have shown that they can survive for over two years without food, so simply eliminating their food sources won’t be enough to eradicate them.
Yes, but they aren’t aggressive toward humans. Brown recluse spiders prefer to run away when disturbed; bites usually happen when they’re accidentally pressed against the skin.
Yes, they are venomous spiders. While most bites result in mild symptoms—such as a red bump with a small ulcer—some can lead to necrotic wounds where tissue damage spreads. Serious reactions are rare, but it’s always best to have a doctor monitor any suspected brown recluse bite.
Seek medical attention. While most bites heal without complications, brown recluse venom can cause hidden tissue damage beneath the skin. A doctor can monitor the wound and take action if needed to prevent severe tissue loss.
These spiders stay close to the ground and enter through small openings near the foundation. Common entry points include:
Unlike other spiders, brown recluses don’t use their webs to catch prey. Instead, they weave them in protected areas as a retreat. You might find their webs near the ground, in wall voids, or inside structural cavities. If you come across webbing in these areas, proceed with caution.
Because brown recluse spiders are nocturnal, they often go unnoticed. However, there are a few signs to watch for:
