Product Review (submitted on October 2, 2015):
I had a yellow jacket nest in a masonry wall that had been covered with cultured stone on a large patio. This stuff did the trick! The nest entrance was in a corner about 5' up a 9' wall. I was able to spray into the area above the nest area in the corner and the product ran down the corner where their nest was located. I ended up applying the product 3 times but after that, no further activity.
