Delta G Granules is labeled for digger wasps. Broadcasting the granules with a hand spreader may stop some of the activity but you will usually still end up with some activity that must be treated by applying 1 to 2 teaspoons of granules in and around each individual ground nest opening. We recommend making the application at dusk when wasps are not active.
