Toxicity
Wolf spiders are capable of defensive bites, and some South American species may give bites that are medically significant. Nevertheless, the presence of wolf spiders is considered favorable to some because they consume undesirable arachnids.
Wolf spiders will inject venom freely if continually provoked. Symptoms of their venomous bite include swelling, mild pain and itching. In the past, necrotic bites have been attributed to some South American species, but further investigation has indicated that those problems that did occur were probably actually due to bites by members of other genera. Australian wolf spiders have also been associated with necrotic wounds, but careful study has likewise shown them not to produce such results.
