Here in New Mexico, there is a black widow under every rock and piece of wood. So what? You just check your shoes before putting them on. Something like 60 or so die every year in Japan from the anime mecha-hornets. More people probably die of bee stings. I’ll take my chances.
My understanding is the problem is what they will do to the bee population.
Bees don’t attack unless provoked or someone is extremely unlucky to disturb them. I learned this the hard way as a kid.
