I used to hate wasps with a passion.
Then I watched this documentary about them. It turns out they are very good predators and feed on these HORRIBLE little mites that are just gross. It turns out that if it were't for the humble wasp, we would be overrun with these terrible little mite things, and believe me they were HORRIBLE!
So now I have a new tolerance for wasps, and just give them a respectfully wide berth, but don't kill or harm them!
