There is always an alternative.Seven dust is death on bees , but if any of you get a nest of yellow jackets in a bad spot.use a squeezeable bottle to blow the dust in the hole, if it gets on a few, so much the better. They are history.
Dish soap and water kills yellow jackets with less damage to the rest of the environment.
