This look familiar?
http://www.coopext.colostate.edu/4dmg/Pests/flyant.htm I'm going to add a personal experience here.
How many of you have had a wasp or bee come in to where you're printing? You don't want to swinging things or start spraying wasp spray everywhere, right?
So what do you do?
I keep a shop vac around. When one of them winged pests come inside, I just turn on the shop vac, find the bugger, and THHHUUUUUMMMMMPPPPPP.
I figure his wings get a bit messed up and by the time he figures out how to separate himself from the dust and debris in the bottom and start hiking out, he'll be history. Never have seen one exit.....alive.
