Hobo Spiders vs. Brown Recluse Spiders: Everything You Need to Know

Blog Article

Hobo spiders and brown recluse spiders are often confused due to their similar appearances, but they have distinct characteristics, behaviors, and venom effects.

Hobo spiders (Eratigena agrestis) are commonly found in the Pacific Northwest of the United States. They have light to dark brown bodies, with a distinct chevron pattern on their abdomen. Hobo spiders are fast runners and typically build funnel-shaped webs in basements, garages, and woodpiles. While they were once believed to have a dangerous bite, recent research suggests their venom is not medically significant and does not cause necrotic wounds.

Brown recluse spiders (Loxosceles reclusa) are primarily found in the Midwest and Southern U.S. These spiders are light brown to tan and have a violin-shaped marking on their cephalothorax. Unlike hobo spiders, brown recluses are true recluse spiders, preferring to hide in undisturbed areas like attics, closets, and under furniture. Their venom contains a necrotic toxin that can cause skin ulcers, although severe reactions are rare.

One key difference between the two is their eye arrangement. Brown recluse spiders have six eyes in pairs, while hobo spiders have the typical eight eyes arranged in three rows. Additionally, hobo spiders are more aggressive when disturbed, whereas brown recluse spiders prefer to retreat.

If you suspect a brown recluse infestation, professional pest control is recommended due to their venomous bite. For hobo spiders, sealing entry points and reducing clutter can help keep them away. Understanding these differences can help in proper identification and prevention.
