Despite their possibly mistaken description as aggressive house spiders, hobo spiders generally only show aggression when their webs are disturbed or provoked, usually by humans unaware of these arachnids nesting in the dark spaces of their basements. Extremely protective of their young, hobo spiders will attack and bite intruders in the act of defending their egg sacs.
Initially, hobo spider bites were thought to cause necrotic lesions similar to, but less severe, than brown recluse spider bites. Later research has not confirmed any cases of necrosis from hobo spider bites. Also, an initial study on rabbits produced necrotic lesions in the subjects but subsequent experiments failed to produce similar results.
As purported headaches, vision abnormalities and overall unwell feelings have yet to be confirmed by an expert as definitive effects of hobo spider bites, arachnologists do not consider hobo spiders to pose serious health threats to humans. Because hobo spiders can be mistaken for brown recluse and wolf spiders, bite victims should consult a healthcare professional if they experience severe headaches, vision abnormalities and/or enlarging skin-eating lesions that develop at the bite site.
