It's something I discovered by accident one day when all I had on hand to take out a wasp was a spray bottle of alcohol. I was just trying to wet it's wings so it couldn't fly; surprised the heck out of me when it killed it! I'm forever having to deal with them in my greenhouse and the wasp spray was just not something I wanted to use around edibles. The straight alcohol will burn some plants, tho, so now I just don't put plants in the window where the bugs like to land.
