TERRO Outdoor liquid ant baits attract and kill common household ants. To use this outdoor liquid ant bait, simply place the pre-filled, ready-to-use liquid bait stations outdoors in areas where ants are observed and, if desired, secure the baits with the stakes provided. The patented outdoor ant baits prevent the liquid bait from drying out, providing the ants with a continuous supply of food, day and night. Ants typically follow defined trails from the nest to food or water. Placing the outdoor ant baits close to these trails will improve control.
