Unlike black widow spiders, wolf spiders are big hunting spiders that don’t rely on webs to catch their prey. In the United States, you’ll find two especially common wolf spider species: Hogna carolinensis and Tigrosa aspersa. The Lycosidae family they belong to are arachnids with athletic, hairy bodies and a notably large body size.
Quick answer: how to actually control them
Because wolf spiders hunt on foot rather than building webs, glue traps work well against them — far better than foggers, which don’t reach where they hide. Catchmaster spider glue traps placed along baseboards, garage entrances, and basement walls intercept them on their hunting paths.
The word “Lycos” is Greek for “wolf,” a nod to their wolf-like hunting habits — though wolf spiders are actually solitary and hunt alone, not in packs. Related: How to Control Spiders.
Wolf spider appearance
If you’re picturing a traditional web-spinning spider, wolf spiders won’t match that image. They don’t spin webs at all — instead, they actively hunt down prey like their namesake. Their build has some similarities to tarantulas, but they’re considerably smaller and from a different family entirely.
Wolf spiders have brown-to-gray, hairy bodies with varied markings. Males typically run 18-20mm in length, while females are somewhat larger at 22-35mm depending on species. Their darker coloring helps them camouflage from predators and approach prey unnoticed.
Hogna ingens, the Desertas wolf spider, holds the record for the largest body size in the family, with a leg span reaching about 12cm.
Wolf spider eyes are arranged in three distinct rows: four small eyes in the front row, two larger eyes in the middle row, and two medium eyes in the back row. The oversized middle-row eyes are one of the most distinctive identifying features of the family.
Another reliable ID feature: check the fangs. Wolf spiders belong to the infraorder Araneomorphae (“true spiders”), which have pincer-like fangs oriented side-to-side — this is what separates them from small tarantulas, which belong to the infraorder Mygalomorphae and have vertically-oriented fangs. Compared to brown recluse spiders, wolf spiders have shorter legs and lack the violin-shaped marking behind the head that’s characteristic of recluses. Related: Getting Rid of Brown Recluse Spiders.
Wolf spider behavior and habitat
As active hunters and fast sprinters, wolf spiders chase down prey rather than waiting in a web. They’re found across a wide range of habitats: rainforests, alpine meadows, wetlands, coastal forests, shrublands, deserts, and woodlands, with some species comfortable in suburban gardens and riverbanks too. The ITIS database lists roughly 2,400 wolf spider species across 123+ genera worldwide.
A key identifying behavior: wolf spiders retreat into burrows or crevices rather than webs when disturbed. You’ll find these burrows around outbuildings, house foundations, and near windows or doors. They stay close to the ground and rarely climb onto tall objects — a habit that separates them from many other household spiders.
During spring and summer, female wolf spiders carry a white egg sac attached to their abdomen, and once spiderlings hatch, they ride on their mother’s back for a period afterward. Wolf spiders hunt both day and night thanks to strong night vision, though their eyes reflecting light in the dark makes them easy to spot with a flashlight after sunset. They typically enter homes through breezeways, crawl spaces, and basements, and their diet consists mainly of crickets, other spiders, and ground-dwelling insects.
How dangerous are wolf spiders?
Wolf spiders bite humans only when mishandled or when they feel directly threatened. Per Penn State Extension, wolf spiders are venomous but not medically dangerous to people — their venom is built to subdue small prey, not to harm humans. Most sources describe the pain and severity of a wolf spider bite as comparable to, or milder than, a bee sting, with redness and localized pain that resolves on its own.
If you spot a fast-moving spider out in the open during the day, it’s far more likely to be a wolf spider than a brown recluse — recluses are reclusive by nature and rarely venture into open, visible areas.
Conclusion
If you spot a wolf spider, the safest move is to avoid handling, touching, or squishing it — squishing a female can rupture her egg sac, releasing dozens of spiderlings into your home at once. For ongoing control, glue traps along baseboards and entry points are more effective than sprays or foggers, since wolf spiders hunt on the ground rather than flying or building webs that a contact spray would reach.
