It's under a porch. Don't they go dormant, and then maybe a shopvac could be used to gently remove the eggs to a more desirable location?

I'd love to pick them up but I'm about 1300 miles away. PM me if anyone is interested. So far they haven't stung anyone, homeowner blocked off one location after spray failed (you knew that was coming, right), and they have a default entrance. Which might mean 2 ways to get them out.
