It can be difficult to identify a hobo spider simply by the way it looks. Long legs, a brown body, and a grayish abdomen with yellowish markings are typical of many types of spiders.
There are over spider species in the region that look similar. The hobo spider belongs to the funnel-web spider family. These spiders make funnel- or tube-shaped places out of their silk to hide in. They can run quickly, up to 3 feet per second, when moving from place to place. Most spiders in this funnel-web spider family are harmless or only cause minor bite reactions. This is when male spiders are searching for females to mate with. You may be bitten by a hobo spider and not even realize it.
Their bite is almost painless, and it may feel like nothing more than a pinprick. One study in Oregon was able to verify a hobo spider bite. The individual reported pain, redness, and leg twitching that lasted 12 hours. Unlike other spiders that have been shown to cause this condition, hobo spider venom is not considered toxic to humans according to the Centers for Disease Control and Prevention.
This is supported by studies where hobo spider venom was injected into animals and failed to show any skin reactions. Spiders in the United States that have toxic venom dangerous to humans include the black widow spider and the brown recluse spider.
Any skin lesion that is red, painful, blistering, or turning black requires immediate medical attention. Spider bites are often blamed for many skin conditions.
They like dark, damp spaces. Mating season lasts from June to October. At this time, male hobos may enter ground structures of buildings as they roam around and look for a mate.
They do not live inside buildings. Very few studies have looked at confirmed hobo spider bites. For this reason, experts are not sure exactly what the symptoms are. Past studies have linked a range of effects to hobo spider bites. However, experts now believe that most of these effects came from other spiders, notably the brown recluse.
It now seems most likely that the initial bite from a hobo spider will cause a slight prick or sting, and that minor skin irritation may follow. Not many researchers have focused on an identified hobo bite. In a single study , a person experienced some minor pain and redness with a hobo bite, but these disappeared after 12 hours. Some people have reported tissue death necrosis after a hobo spider bite.
However, the authors of this study did not find any evidence to support this. Some insects and spiders can introduce bacteria into the body when they bite. The hobo does not appear to do this.

While poisonous bites are rare, any bite—spider or otherwise—can turn serious if it becomes infected, says Arnold. There are three main complications that can arise from bites: cellulitis, blisters, and swelling , says Arnold. When a spider bite turns into cellulitis—a common although painful skin infection—a rash begins to spread around the wound, and the skin becomes painful and hot to the touch.
Another common reaction to many spider bites is to get "weeping" blisters at the site they look puffy and fluid-filled. Small blisters on their own, with no other symptoms, don't necessarily need special care. But if a blister opens, it becomes at risk for infection, says Arnold, so don't try to pop them! If you think you may have an infection at the bite site, whether from cellulitis or open blisters, it's best to have your doctor take a look.
