I live in So Ca, Black widows are a way of life here.
Biggest issue with them besides the nasty painful bite, is the freaking webs, strong sticky things that not only freak you out since you know that it's a black widows web, they are a pain in the ass to get off.
I keep my dirt bikes out side, and one while working on it, I move around to under it and I find a nice big BW hanging out in the little shark fin for the rear rotor. This was on the same bike that I had killed some wasp/hornets/yellow jackets nest that was just starting to form.
It reminded me that I need to ride my dirt bikes more often.
