Dry (powder) insecticide to kill yellowjackets in wall

[BCDrums]

I found yellowjackets entering the exterior wall through a little hole. I set up a shop vac near the hole and caught all the bugs entering and returning, and now the nest seems deserted. I was going to spray Sevin in the hole, but found out from the manufacturer that it is not meant for yellowjackets.

Is there a powder I can spray into the wall, rather than a smelly wet insecticide? I have a can of spray stuff, but I'd rather use something orderless and dry, if there is such a product.

Thanks! BC

... If you got the bulk of them and really don't want to use the wasp spray for some reason, I'd just caulk up or otherwise repair the hole and go on...

I agree. I had some nesting in wall, getting in around a porch lamp and did not want anything wet around the wiring. Caulked around fixture and sealed them in. Took a few days for buzzing to subside.

You can use Sevin.

I've personally seen it work just fine.

7 is perfect for yellowjackets, its honey bees, that it will also decimate their hive, ive klilled over the years maybe 20 nests with 7, its easiest safest with 7

Diatomaceous Earth (ant powder) and caulk up the hole. Shop Vacs work great on yellowjackets. I vacuum up a half gallon of soapy water first to drown them.

Thanks for the links. They do recommend Sevin. I may just seal it up; I think I got almost all of the critters with my shop vac, which I ran all day yesterday on 'em.
