How long does it take to eliminate an ant colony with Terro Liquid Ant Bait?
This is a BAIT type product and will initially attract lots of ants. The ants consume large quantities of the bait and then return to the nest and share it with the rest of the colony, including the queen, eventually eliminating the entire colony. This process can take from just a couple days to several weeks, depending on the size of the colony. Each ant that consumes the bait will die within 24 – 48 hours. It is recommended to leave the bait station as undisturbed as possible while the ants are actively feeding on it. You should replace it only if it becomes inaccessible to the ants, or empty.
