I've got aggressive monster blue black wasps that won't die with wasp killer spray!!!! Help me please?
I live in Massachusetts. I have an inground pool and the nest is under the edging of the pool. They're HUGE like 2 inches long and they're black with a blueish hue and frequently carry grasshoppers into the nest. I'm not sure but from researching they might be digger wasps That's what wikipedia says but when I google image search them it's not the same looking wasp. I've tried killing them with wasp/hornet spray but the dam things are invincible and the spray doesn't even phase them! Last year I killed a handful of them by stalking and smacking with my flip flop which isn't easy because they're fast and very aggressive. You can't get within 10 feet of the nest and they after you. I have dogs, curious dogs. And kids. Kids with friends that like to come swim but everyone's afraid to go out there because of these things. What's the right chemical to kill them with I've tried this wasp killer
