I followed the directions in this video: Took a gallon of typical cheap Apple juice, made some bait stations out of milk jug and juice jugs added Boric acid to the apple juice, then put the bait stations around my shop and pole barn.
Apple juice: any store in the country will have it; cheap stuff is just fine. Boric acid - $10 at amazon: https://www.amazon.com/dp/B014JJ9846?tag=atomicindus08-20
A whole lot less wasps and yellowjackets this year around here.
