Yellowjacket nest expansion has peaked for the year. And very soon it will be abandoned. Yellowjackets produce annual nests, starting in spring from a single queen, and nests are abandoned - and not subsequently reused - in late summer.

If you can wait, this should be resolved on its own by early October.

Some information on yellowjackets is at: http://bspm.agsci.colostate.edu/files/2013/03/Yellowjackets.pdf
