Oh that's a great idea! I didn't know diatomaceous earth worked on wasps.

I've used it to keep ticks and fleas out of the lawn area my dogs play in, and to get rid of ants.

I don't know why it didn't occur to me to dump it on the wasps, I guess I just thought they were too big? Doesn't it work by puncturing their exoskeleton and basically sucking all their fluids out?(I could be misinformed on that)

Either way I'll go that route if I run into that issue again! Then I don't have to worry about contaminated areas of my lawn.

Thank you for the tip!!!
