"The Surprising Cause of Most 'Spider Bites'"

"The vast majority of "spider bites" are caused by something else, research shows. One study Vetter cited found that of 182 Southern California patients seeking treatment for spider bites, only 3.8 percent had actual spider bites, while 85.7 percent had infections.

And a national study found that nearly 30 percent of people with skin lesions who said they had a spider bite actually had methicillin-resistant Staphylococcus aureus (MRSA) infections. Other things that can cause symptoms that mimic spider bites include biting fleas or bedbugs, allergies, poison oak and poison ivy, besides various viral and bacterial infections, Vetter said."

Huh. I actually recently had a skin infection that I assumed was a spider bite at first (until I realized there was no break in the skin).
