Okay brain trust...

I've got two rather large gound dwelling bumblebee nests in my yard. Both located right near where I've got to do some digging for some outdoor plumbing fixes. So they have to go.

These are the "Big as your thumb" hairy version...

I've tried natural remedies like flooding them out, vinegar - not even a dent. I've tried spectracide insect filler. I've tried Ground dwelling bee and yellow jacket foam spray. An entire can down the hole over the course of a week. I've tried Sevin dust....

...they won't DIE!

I'd rather not use gasoline/brake cleaner remedies because it would kill the grass and possibly contaminate my well.

so....

HOW DO I KILL THESE THINGS?
