Product Description:

TERRO® Outdoor Liquid Ant Baits attract and kill common household ants.

To use, simply place the pre-filled, ready-to-use liquid bait stations outdoors in areas where ants are observed and, if desired, secure baits with the stakes provided. The patented outdoor ant baits prevent the liquid bait from drying out, providing the ants with a continuous supply of food, day and night. Ants typically follow defined trails from the nest to food or water. Placing the outdoor ant baits close to these trails will improve control.

How Does It Work?

While the active ingredient in TERRO® Outdoor Liquid Ant Baits will ultimately kill the worker ant, it interferes with the ant's digestive system and works slowly enough that the worker has time to get back and share the ant bait with the rest of the colony. This slow kill is needed to allow time for the foraging ants to make several trips to the bait and deliver enough bait to the rest of the colony. Baiting enables you to get rid of both the ants you see and the ants you don’t. Complete control may take up to two weeks.

Works Great For Small Black Ants By Gee_Whiz
I bought these outdoor baits for small black ants that were swarming in the grass in front of the house. The ants were attracted right away to the bait. I used another outdoor bait station inside the house, as the ants were coming out of the wall. They were slow to find the bait, which I set up on an upside-down margarine lid. Once I directed the ants to the bait station, they started coming. In a few days, they were pretty much gone.

The RAID dual action type bait stations I bought previously never worked.

Give it some time? By bluegirl

I have had 2 of these in place for 3 weeks for an infestation under the concrete of my pool deck. So far I have not seen an improvement. The ants are a combination of small ants & winged ants. The ants have sampled the bait a ton, but so far there is no decrease in population.Daily I have clumps of ants floating on my pool. FYI the 4 legged critters(squirrels I think) love it too as they have destroyed the traps & I had to replace them.

Patty : Consumer Relations Representative

We appreciate the time taken to provide this feedback and apologize for the experience.  

This bait is designed to kill the ants that consume it within 24-48 hours. This allows them time to take the bait back to the colony to share with other ants. Depending on the size of the colony, it may take several weeks until a decrease in numbers is seen. We recommend continuing to apply the bait until there is a sharp drop in the number of ants. The colonies of some species, such as Argentine ants, can be as large as a city block with hundreds of queens.

Q.Does this work for carpenter ants?

This product is not recommended for carpenter ants.

Q.Will Terro liquid ant bait kill fire ants

We apologize as our liquid bait is not recommended for fire ants.

Q.What happens when it rains. Such as, does the trap harm the soil by leaking?

No, water would simply dilute the bait. This trap has been designed for use in soil. If used in a vegetable garden, we would just recommend washing fruits or vegetables before eating.

All About


There are more than 10,000 known species of ants living throughout the world. Like other insects, they have six legs; each with three joints. Ants have large heads with compound eyes, elbowed antennae, and powerful jaws. Ants are social insects that live in structured nest communities throughout the world. The species of ant determines whether they live underground, in mounds built at ground level, in wood structures or in plants or trees.


What’s the difference between liquid and gel ant baits?

It’s a little known fact that adult worker ants cannot digest solid food (bait). Their anatomy is designed for transporting and digesting liquids only. Solid foods must be carried back to the colony for additional processing by the larvae stage. Liquid baits exploit this unique physiology by making it easy for ants to transport the liquid bait back to the rest of the colony, including the queen, larvae and other workers.

I just placed several TERRO Liquid Ant Baits on my deck and it’s attracting more ants, not killing them! What’s going on?

You have nothing to worry about! Initially, you will see more ants. As ant foragers look for food, they are attracted to the sweet liquid in the bait which they consume and carry back to feed to the rest of the colony. On the way back to the nest, the ants drop what it called a ‘trail pheromone’, letting the other ants know where the tasty food supply is. In turn, these ants follow the trail to the bait which explains why you initially see more ants.

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 to get back and share the bait with the colony. Baiting is the only way to successfully wipe out the ants you see and the ants you don't.
