Yellowjackets -- the wasp/hornet

Been about 12 hours. Went to look-see. Lots (dozen or so) hanging and landing on entrance, flying off and replaced by others, but there is now a second hole about 8 inches from original and they seem to be using it. It appears to tunnel laterally for a bit.

Really can't get a good look at original hole without major risk and can't see if they have cleared it, so hoping the original dusting will do them in, but I will risk it tonight and try to treat second hole and maybe get a better look at original entrance.

 

Second night strike. First hole pretty well covered except for small corner with insecticide. Bombed the additional hole, but unlike last night no guards appeared.

.SHRUG....

Well, will check in the morning.
