 Leave them alone. They're loners. They don't want to be around humans. That's not their purpose is to be around a human. And if you do get bitten by one, if that's what is actually known, because sometimes they think they're spider bites and they're treated as such, but it's probably not just exactly a spider that has bitten them. Like I'm terribly allergic this year to mosquitoes. I've always been allergic to them.
