After all, there's a risk that the uninvited guest in question may be a brown recluse — a venomous spider whose bites may sometimes turn necrotic. But more often than not, the creepy crawly in your house may be a benign hobo, one of the many spiders that gets mistaken for the big bad brown recluse. Since hobo spiders are highly variable across ages and sexes, identifying them correctly is challenging. Besides, as members of the funnel spider family, they share characteristics with several other species, like grass or domestic house spiders, adding to the confusion. In fact, the common refrain is that it's easier to rule out a hobo spider than it is to identify one.
