Wolf Spiders are actually really awesome to have around! They are wonderful hunters and can keep pest levels down. They are almost always found outdoors, though sometimes they'll end up inside by accident. If you find one, don't kill it! They can be herded into containers and transported back outside, where they are sure to keep away centipedes, beetles, cockroaches, and all sorts of other arthropods.
Wolf Spiders are abundant. Lycosidae has members across the world, and more than 125 species in the United States alone. Wolf Spiders have been known to bite humans, though it is rare and typically only happens when they are directly handled. They are poisonous, but it is mild and gives a similar reaction to a bee sting.
