My preference would be to live peacefully with them, since I’ve read that some wasps are good for gardens. But right now about a dozen wasps are very active in the lawn near my kids’ swingsets, and it’s just a matter of time until someone gets hurt.
These particular wasps have dug 1" wide holes in the dirt where our lawn is thin. I’m not sure exactly what they’re up to down there, but it seems to keep them very busy.
If only they’d sting the Japanese beetles…nah, I’m having fun drowning those suckers on my own. Particularly when I catch them in “the act” – all those bugs do is eat and fornicate, the rose of sharon and mallows have been hosting orgies all summer.
