The Dominion 2L is not labeled to treat for stink bugs and we would not recommend using for this pest. We have put together an Overwintering kit that is just for stink bugs. This kit includes Demon WP insecticide with Cypermethrin, Eco PCO dust and a hand duster for easy application. You should treat once a month through November for best results
Dominion 2L is not in the form of crystals, it is a liquid concentrate. It is is labeled for white flies as a systemic control. It is not a fertilizer. We recommend for white fly control that you measure the height of shrubs and diameter of the trees and apply the solution as a soil drench. You can apply Talstar P for a foliar spray (on not edible trees and shrubs) while the systemic control is working for immediate control.
Dominion 2L should be applied (1 ft up and 1 ft out) directly up against the structure once every 6 months for a topical barrier for carpenter ants. We also recommend that you bait for them. We carry the Dominion 2L along with a gel bait and a granular bait in our Carpenter Ant Kit #2.
