[Dragonfly DIY] Impromptu insect duster

I discovered a ground wasp nest the hard way while mowing today. So tonight after they stop swarming around and go to sleep I need to deliver some insecticide dust to them but I don't have a duster.

But I do have an empty peanut butter jar, some thin plastic hose, an automotive valve stem (one out of an old bicycle tube would work fine too) and a bicycle pump.


I used a taper drill bit to get to the right size for both of these, you want a tight fit so take it slow.

Put the powder of choice in there, wait until night when the bugs are settled down, use the pump to blow the dust though the pipe and into the nest.

I've used this method before for various nests. When it was a large nest in the attic, I built a duster out of 4" and 1" PVC with reducers and used an air compressor with a blow gun nozzle on it to completely flood that part of the attic. In that case I used diatomacious earth so that I wouldn't be pushing toxins into my house. When I need to go for a quicker kill I'll use Sevin dust, and boric acid (Roach Prufe) works well too.
I hadn't gone within 10 feet of the swarm when they were riled up, but a couple of hours after dark I went in with a head lamp and this rig.

There was a finger sized hole there, I pushed the hose in a little and gave it a whoosh, and a few dust covered bees came staggering out, but didn't fly. I pushed it in a little farther and gave them 4 or 5 more whooshes. I expect that should do them in. I used Sevin dust which in the past has been very effective for me.

My face still doesn't feel right, though it doesn't exactly hurt anymore, it just feels a bit twitchy around where the sting went in.
