Assuming you are referring to the popular Terro Liquid Ant Baits they claim that you will see results in as little as 6 hours. However results will vary based on the level of infestation. 1-2 weeks is a more realistic timeline for a noticeable decrease in ant activity.
As for how the bait works the worker ants collect the liquid bait and take it back to the nest where it is fed to the rest of the colony. Because the bait contains borax an ant poison it will eventually kill the entire colony.

“The TERRO® Liquid Ant Bait system consists of small portable stations that can be placed near indoor and outdoor areas where ants are seen. These stations are designed with a deep well to keep the liquid bait protected from the sun and elements until ants are able to feed. The liquid bait is specifically formulated to attract and kill all common household ants.”
