You guys are too funny. We've had an population explosion of various wasp species this spring probably because we've had plenty of rain. I usually get a warning buzz by the sentry wasp, and if the nest is located in my territory they get zapped by RAID. One thing I learned about Wasp and Hornet spray is to avoid the generic brand, and make sure the nozzle is pointed at the nest and not your face, the dog, or the hubby. Although the WD 40 and a lighter does intrigue the pyromaniac in me.......
