Good call. Probably a month too early. Just now getting the random wasp nest started around the house. BTDub...I fucking hate wasps. They will never last more than a day or two around my house. I keep a can or two of Spectracide 30' spray at the ready to wipe out those nasty sumbitches. Killed one of those wood drilling bumblebees tonight while I was grilling. They say those won't sting you. Fuck that. Death is the only alternative for them.
I'm a Raid Hornet & Wasp spray guy. That stream kills those bastards on contact. We had a colony of guinea wasps that built a big assed nest in the roof of our patio in Italy. They found a crack between the gutter and roof tiles to get in. I found this and fired a good dose into the crack. Wound up with 27 dead wasps off that one nest.
When I was a kid, we'd find a nest and squirt it with a water gun. They'd dive after us, and we'd swat them with ping pong paddles. It definitely builds up an exceptional hand/eye coordination.
