Wasp ground nests
I read that the wasps will die after 2 hard frosts. But the new queen hibernates and a new nest starts in the spring. How can I prevent this from happening? In Minnesota hard frosts will happen, I don't want another ground nest next spring. Thank you for your time.

The "ground wasps" you are referencing are most likely Yellowjackets. There is no practical way to find and kill a hibernating queen. She may not be hibernating anywhere near your property. Also, a hibernating queen may come from somewhere else and find a nest site near you.
The good news is they don't reuse a nest so they won't be in that nest next year,
Below are a couple of references if you want to learn more:
Thank you for your quick response. It went to my junk mail. Doesn't indicate university of Minnesota, concerned it was a scam. Got brave today, read your response. Good news the queen won't return, quite the hole, will fill it so it doesn't have any more tenants. Thanks again.
