White Tail Spider Bite
White-tailed Spider bites have been implicated in causing severe skin ulcers in humans but not everyone agrees. It does make for good ratings on A Current Affair where facts should never get in the way of their BS that they propagate as truthful stories. (Oops, too much?)
G.K. Isbister and M.R. Gray carried out a 2003 study of 130 definite bites by White Tail Spider (Lampona species)
Conclusions: Bites by Lampona spp. cause minor effects in most cases, or a persistent painful red lesion in almost half the cases. White-tail spider bites are very unlikely to cause necrotic ulcers, and other diagnoses must be sought.
