How Do Terro Liquid Ant Baits Work

The active ingredient in the bait interferes with the ants’ digestive systems, eventually killing the ants within 24-48 hours after consumption. This slow kill gives the worker ants enough time to make multiple trips to the bait and share it with the colony and queen.

How long does Terro liquid ant bait last?

You’ll want to replace with fresh bait if it becomes hardened or if you’ve had the same bait for more than one year. Another good rule of thumb is to check the product packaging for specific information on how frequently to replace. For instance, the T300 TERRO® Liquid Ant Baits should be replaced every 3 months.

Do ants learn to avoid Terro?

Good Luck! Sometimes ants appear to be ignoring baits. This will happen with all ant baits. Ants tend to find and feed on foods dependant on the needs of the nest or colony at the time.
