Black widows aren't that common. At least in my area. Maybe further south. It seems the further south you go the bigger the insects get and the more things there are that want to kill you.

Brown recluses are a bigger problem, but they avoid places with much foot traffic. I'm always paranoid cause there are a lot of lookalikes, but their bite isn't an immediate death sentence. It'll give you necrotizing fasciitis, which is a slower and more painful process and could eventually result in death but by that time it's usually obvious there's a problem and you need to go to the hospital. Still a cosmic horror though. But the bites aren't too common.

I've literally never seen a black widow in person though
