TERRO PCO Liquid Ant Killer offers flexibility, controlling ants indoors and outdoors with no unpleasant odors. It is labeled to control several common sweet-eating ant species, including Argentine, ghost, little black, acrobat, pavement, odorous house, crazy and cornfield ants. Ants feed on the borax-based bait, carry it back to the nest and deliver a dose to the colony. It’s available in three sizes: 1 gallon (4/case); 16 oz. (12/case); and pre-filled bait stations (300/case).
