For ant management, the first step is to locate ant trails, nests or mounds, and areas where the ants may be expected to forage. After that, it’s all about choosing treatment. Select an insecticide that is non-repellent, may readily be picked up from a dry deposit by foraging workers, and has the ability to be transferred throughout the colony.
The active ingredient fipronil is known to be effective against many ant species, for example. It may be applied to the outside surfaces of labeled structures, into wall voids and as a perimeter application 1 foot up and 1 foot out from where the ground meets a structure’s foundation.
