yellow jackets are bald, and have a pinched waist

If they're in the ground, they're not likely to be honeybees (especially in your part of the country).
I'd say, get rid of 'em!

For photos, go to Google (I'm sure the same would work for Yahoo and other search engines), click on the "Images" selection above the search box, type in 'yellowjacket' and search; then do the same for the word 'honeybee' (make sure you're still in the "Images" selection). As they say, one picture is worth a thousand words.

Thanks to you both. Well, I have yellow jackets. My husband has found another hole in the field where they are comming out. We know how to get rid of them. I just wanted to make sure that why I ask. Thanks a bunch for the help.

And curiosity has got the best of me.
What technique will you use to get rid of them?

My technique would be to simply dump some Sevin Dust in the hole just at dark (assumming you're not adverse to the use of chemicals).

Or, if you can avoid the area for a while, simply wait until winter when the colony will die.
