I forget where I learned about using wasp spray. The good part about it is you can stand back and not be in bite range. I'm not sure it kills them but as soon as you spray them, they curl up in a ball. I divided the little feller in half after that.Interesting. I kill three to six Western Diamondbacks on my porch every summer. I keep a hoe handy just for that purpose. Does wasp spray take snakes out? The hoe works like a charm but you can't have too many alternatives.
