A previous thread suggested using a shop vac near the opening (running all
day) to cut their numbers down. I agree 100% with the use a powder instead
of a spray.

We have a ton of yellow jackets around this year! We did spray some of the
nests but one is in our cellar window well. They seem to have found an
opening into the framework around the window and are somewhere inside the
cement block foundation. They are constantly flying in and out all day! We
tried spraying but we don't see an opening,they are so quick! Is there
anything else we can do to eliminate them?They are in an area where my
dogs are kept so every time the dogs go near they attack!ANY help would be
appreciated!
