TERRO Outdoor Liquid Ant Baits are ideal for large ant infestations. It attracts and kills all common household ants including Argentine ants, ghost ants, cornfield ants, pavement ants, acrobat ants, white footed ants, little black ants, odorous house ants and other sweet eating ants. To attract and kill ants, simply place the pre-filled, ready-to-use liquid bait stations outdoors in areas where ants are observed and, if desired, secure baits with the stakes provided. The bait stations can also be placed on decks, or in garages or basements without using the stakes. Ants typically follow defined trails from the nest to food or water. Placing the outdoor ant baits close to these trails will improve control. The patented outdoor ant baits prevent the liquid bait from drying out, providing the ants with a continuous supply of food, day and night.
