They're predators that attack other pests. but, I understand, they have to go.

DE (diamatecous earth), dusted around the entrance will be effective, but it will kill any insects, including beneficial bees & butterflies that come in contact.

#smij doesn't like man-made pesticides. they poison everything

I have diatomaceous earth, I dusted it around my beehives when they had an ant infestation years ago - would this be a better plan? Will this not hurt my garden?

DE will kill any invertebrate it comes in contact with, including honeybees. that saiid, if you're dusting around the ground wasp's entrance, you probably will just kill them. DE is basically calcium and won't otherwise hurt your garden.

I wouldn't use brake fluid or any petroleum based pesticides.
