Arizona has to be the most habitated area for black widows.

After working around a dry wood pile one day I felt something on the underside of my arm, turned it over and noticed a king size black widow the size of a quarter with a big black booty.

Got it off just in time.

According to some bitten by widows it is extremely painful on every nerve of the body for days.

I only fear two spiders, the black widow and brown recluse.
