I found a bunch of wasps coming in and out of a mole hole so I sprayed inside the hole then dug  around and found the nest and removed or atleast I think I removed most of it. A couple hours later there’s still wasps hovering around that area? Is this normal and they’re just looking to go where they once were or is part of the nest still in there?

Sounds like my ex-girlfriends.

Good question. It’s impossible to tell when I’m running away, quickly. 

They come back to where they remember the nest was. If it’s a handful you’re probably fine. If it’s more than a dozen or so I’d say you have more work to do. I hit a nest in some roots and a hold with the mower a few years back. I’m not proud of the noises I made running away with them all under my shirt and shorts.? …it’s funny now 

Best to wait till after dark when all the wasps are in the nest for the night, then spray the heck out of em. Doing it in the daylight will only get the ones in there, and not the ones out flying around. 

Those ground nests are wicked.  I found one by accident a few years ago mowing the lawn.  I had no idea it was there and I got stung in the leg.  At the time I just thought it was a pebble or debris that the mower had mulched and sent towards my leg.  A couple hours later, it was itching like crazy too.  A week later, the same thing happened in the exact same location mowing the lawn.  Then I saw the dog SPRINT out of the area to the back yard.  Turns out she had been stung above the eye and it was swollen, and I had gotten stung in the leg again.  I immediately quit mowing and went inside to formulate a plan.

 

Shortly before dark, I went back out there with a rock the size of the ground nest entry/exit hole, some lighter fluid, and a match.  I poured lighter fluid down the hole, lit it, and then plugged it with the rock.  I never heard or saw from those yellow jackets again. #burnedalive

Diatomaceous earth sprinkled in the hole should kill them.

I pour gas into the hole after dark. Don’t light it. Kills them dead!

Well about 3

hours later they’re still wandering around that area. 

Be careful around bees.  If you get stung pay attention to your body.  A co workers Uncle got stung a couple weeks ago, went into anaphylactic shock and died.  He had been stung a month or so ago and felt really bad, took benedryl and got better.   This time he was working alone when he got stung.  He called his Wife and was barely able to tell her he couldn't breathe.   If something like this happens to any of you call 911 quick.

Lighting it seals the deal! 

Pour gas in the hole at dusk. Pour a trail away from the hole. LIGHT IT!!! 

Not lighting it will kill them but is MUCH less fun.

Try Apicide Insecticide Dust, go out at night and dust the hole. Just so happens I had a ground nest under the deck that I powdered last night, no bees today. Seems I need it every few years, I’d leave em bee but not with the 2 yo grandson running around.

 

I’ve only had luck finding it online, used to carry it at hardware stores but no more, at least here in Ma. There are other brands.

Sprinkling the entrance with sevin dust will also kill 'em, but again much less fun than a gasoline mushroom cloud.
