Sevin dust completely useless on yellow jackets?
I've been battling yellow jackets and their nest for the past few weeks. I'd be glad to let them live if they hadn't built their nest right next to our entrance gate, plus we have two small children who play out there. I feel bad about using nasty pesticides, but in this case it's justified.
I tried a whole can of that foaming wasp spray. It didn't work. Then I heard about how deadly Sevin is to bees and wasps. I used a long piece of 1/2" pvc pipe to blow two cups of the stuff deeply into the hole. It all went in. The next day my husband dumped another cup right on top of the hole so the yellow jackets had to actually dig through the powder to get into the nest. That was Thursday. Now here we are on Monday and those cursed bugs are STILL walking through that so-called "deadly" stuff. They have a perfectly round entrance hole through the powder, and I watch them walking through it and leaving their footprints in it! It's been four days and we still have hordes of yellow jackets. Did we get out-of-date poison? How long is this supposed to take? We may have to opt for the gasoline approach, but that would be a last resort due to the proximty to a creek. Any suggestions? I really think the nest is too large to be eliminated with traps. We'll try that next spring, but I need solutions now. Thanks!
