Yep. Drop some Sevin dust on them enjoy keeping your Man Card one more week.
You don’t need to use Sevin. You just wait until it’s dark and they go into a torpor. They won’t defend the nest at all. You can take the nest down, relocate it, do whatever you want with it.
We have the little bitty guys who nest in the ground. Gasoline usually fixes the problem. Any petrol based product will ruin the nest for them.
I cut grass last Saturday and ran into three nests in the ground in one area. I always take Raid hornet/wasp spray with me on the tractor this time of year and look for the little buggers flying in the ground. I hammered them with the raid and took care of them. If I find a big one I wait until dark and then take Styrofoam cup with gas and pour into hole, if I am feeling like having some fun then toss a match into the hole and hear the whoof!
Last year in mid-September I was cutting grass around 9:00pm and it was dark and I felt something hit my leg hard, then hit it again and it hurt and I swatted it and through the distant motion light from the house thought I saw a hornet. Sure enough I had run across a nest in the ground on a hill and couldn’t see the hole. I hammered them the next evening at dark but had some nice welts on my leg for a couple of days.
