How Liquid Ant Bait Works

TERRO liquid ant bait works by using borax, a naturally occurring mineral that is toxic to ants. The bait is a sweet liquid that is attractive to ants, and when they ingest it, the borax interferes with their digestive system and eventually kills them.

Initially you will see more ants – but don’t worry, this is a good thing. Why? As ants look for food, they are quickly attracted to the sweet, sugary liquid inside the bait stations. After finding the bait, worker ants consume it and leave behind a pheromone trail leading back to the colony. This trail lets other worker ants know where the newly discovered food supply is. This is why you will see more ants in the beginning.

The bait is designed to be slow-acting, so that the ants have time to carry it back to the nest and share it with the rest of the colony. This ensures that the entire colony is killed, not just the ants that are attracted to the bait.

To use TERRO liquid ant bait, simply place the bait stations near where you see ants. The ants will be attracted to the bait and will start to feed on it. Within a few days, you should see a significant decrease in the number of ants.

TERRO liquid ant bait is a safe and effective way to get rid of ants. It is non-toxic to humans and pets, and it can be used indoors or outdoors.
