When it comes to ants, baiting is the way to go. TERRO Outdoor Liquid Ant Baits can be your one stop shop to rid the yard and home of common household ants. Baiting allows ants to consume the product, survive long enough to carry the liquid back to the nest. The worker ants share the bait with the rest of the colony and the queen. This way you can kill the ants you see and the ones you don't. Since this is a bait product, you will initially see more ants as they are attracted to the liquid - but don't worry, this is a good thing. After the bait is consumed, insect populations will begin to decline. Each station is filled with 1 ounce of liquid, ensuring there is plenty for the ants to feed on. To activate, simply push the bait cup down, twist it to open the bait station, and you are ready to eliminate the colony!
