I tried the shop vac trick today on a ground wasp nest (yellow jacket) and it seemed to work! Long hose on the vacuum and I duct taped it to my fully extended snow rake handle.
I slid the end of the nozzle in front of the hole from 15’ away, ran to the garage and plugged it in.
After running it for about 30 minutes there was no more flight activity around the hole. Kept it running while I dragged it back to safety and taped the opening shut. Now I need to let it sit for a few days in the sun.
i’ll investigate again in the morning. The neighbors probably thought I was crazy out there in a hooded ski jacket, mask and goggles.
