Andrea writes
Hi-Yield Ant Killer Granules contain bifenthrin, which is an insecticide that starts killing insects on contact and then has a residual for several weeks after the application has dried. Depending on the size and health of the individual ants, they can start dying within minutes. Keep in mind that this insecticide is not a transfer product, so if you are treating ant mounds, then you need to follow the label directions for direct mound drenching.
