Note: People have varying sensitivity to spider bites. In rare cases, some individuals with highly sensitive or weakened immune systems may have a significant to severe reaction to a bite from an otherwise harmless spider, and there are many spiders that people mistakenly suspect to be the Brown Recluse. Misdiagnoses are thus very common. (See also University of California Riverside’s Causes of Necrotic Wounds other than Brown Recluse Spider Bites)
