I absolutely agree with getting pepper spray for humans if that’s what you’re worried about & using bear spray for bears. However, if some place like DC won’t let you get human spray so you can defend yourself AND they don’t give you a registration form for bear spray (I have no idea what the situation is regarding purchasing bear spray - I’m speculating), then I’ll take my chances with bear spray. 2.5 million per 3 million ..... I’m thinking a fog of pepper spray is going to be better than nothing & I’ve heard from credible folks that it will put a man down if they get a face full.
As for the wasp/hornet spray, it’s nasty stuff but I haven’t heard of it being used in lieu of pepper spray. I’d never use it. The ultimate irony is that some female somewhere is going to use it on an attacker, survive somehow, and get sued by the attacker for using it on them. The way this world is upside down these days, I have no doubt it’s just a matter of time.
Wasp/hornet spray can travel as far as 40 feet. Nasty stuff.
