i'm looking for suggestions to get rid of a yellow jacket nest. the nest is in the ground right along my front foundation. they are using a hole about the size of a quarter to enter/exit. there are some other holes of the same diameter a couple feet in either direction, but dont seem to be utilized. i was thinking pour some caustic liquid down there and tamp the whole ground area with something real heavy ( 5 foot pry bar with big ball on end ). of course at night when they're all in there. i'd just hate to open another hole up while tamping and become victim..... seems to be a very established nest, judging by the numbers going in/out.
