Those wasps will go somewhere once the Balsam finishes.Just inspected all mine at the 'balsam' apiary, tons of nectar being stored in the brood boxes but not so much being put in the supers.Most of the supers' center 6 frames are pretty full but the outside frames are mostly empty. The best thing about the balsam is it keeps all the wasps occupied,didn't see any around the apiary.
