Bait Application This product can be applied using the syringe applicator or a bait injector. Apply bait in cracks, crevices, corners and out of the way places, such as under and behind kitchen appliances and baseboards, under sinks, around window and door frames, pipes and water heater and in the attic, crawl space and garage. Place multiple application spots of gel where ants are observed actively foraging or entering the structure. If the area to be treated has been recently treated with insecticide, thoroughly clean the area before applying this bait. Do not spray insecticide over gel as this may cause the bait to become repellent. Do not apply to areas that are routinely washed (such as countertops) as bait may be removed or diluted and spread onto the surface.
