My Mum was bitten a couple of years ago by a White Tail. And yes, it was a WT. It was inside the leg of her pants and when it bit her she squashed it and put it in a jar. She had the same as someone else described, as a small irritated area that kept swelling more and more. She squeezed the puss out and thought it would get better. WRONG!!! A couple of days later we had to take her to the hospital, because her flesh was sort of .. decaying, for want of a better word.
The doctor told us that it wasn't "individual's reactions" to the bite.. but in fact the spiders themselves. According the the doctor that treated my mum, it is a bacteria carried on the fangs of the spider that is the problem. Apparently, not all WTs have this bacteria on their fangs, so it comes down to a matter of luck.
As for my mum... every 3-6 months, the original bite area flares up again and starts to eat away at her flesh again. We have had her at numerous doctors and they all have said the same thing. Antibiotics when it flares up, and hope like hell that it's the last time.
I wouldn't be playing with them. !!!!!
