This fine grain application works both by contact and ingestion. It rescues and protects lawns and turf from grubs and other insects that feed on them. Watered properly it can penetrate thatch up to ½ inch thick. It works faster than other competing products, has a longer effective application window than others, kills 2nd and 3rd instar grubs on contact as well as surface-feeding and soil insects, helps stop damage from predators such as skunks, birds, raccoons, etc. Finally, it can also kill bluegrass weevils (larvae and adult), army worms, cinch bugs, cutworms, sod webworms and white grubs.
