Ants can be a problem anywhere – in the home, at work and everywhere in between. To kill common household ants, place TERRO® Liquid Ant Baits in areas where they attract foraging ants that take the bait back to the nest. As the bait circulates through the colony, it kills the ants you see and the ones you don’t. The new and improved snap-off tab makes the stations easy to use. Plus, the closed bait stations prevent the bait from drying out to provide the ants with a continuous supply of liquid, day and night. Note: complete control may take up to two weeks.

How Liquid Ant Bait Works
Since this is a bait, initially you will see more ants – but don’t worry, this is a good thing. Why? As ants forage for food, they are easily 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.
Meanwhile, the active ingredient, Borax, is slowly interfering with the ant’s digestive system, ultimately killing it, but leaving enough time for the ant to go back and share the dose with the rest of the colony. This slow kill is necessary so that foraging ants can make several trips to the bait. The communal nature of an ant colony allows the bait to be spread to hundreds, if not thousands, of individual ants.
Where to Place Ant Baits
Place TERRO® Liquid Ant Baits near trails and other locations where ants are numerous. It’s also a good idea to place bait stations anywhere ants may try to enter your home. The compact size of the bait stations makes them perfect for placement along baseboards, in corners, on counters, under and behind appliances, and on windowsills. The more bait placements, the better!
Easy-Open Tab
Each TERRO® Liquid Ant Bait station is sealed so the bait stays fresh until you’re ready to use them. To open the bait, hold the station vertically and twist the new and improved tab. This opens up the station and allows ants to access the bait. Place the entire station on a flat surface, keeping the ant bait inside the station.
Note: Some earlier versions of TERRO® Liquid Ant Bait required it to be opened by scissors. The new snap-off tab eliminates this method of opening, but some earlier versions may still be sold while supplies last.
How to Use Liquid Ant Baits
TERRO® Liquid Ant Baits are very easy to use. Before placing the bait stations, be sure to remove other sources of food, such as crumbs, sugar and grease spots to prevent attracting ants elsewhere. Do not place bait where you’ve already sprayed insecticides, as the pests may avoid the bait stations.
Hold the bait station firmly with bait pack tab facing up. Break off the tab being careful not to spill the bait.
Place the bait station label side up on a flat surface near signs of ants. Place additional bait stations anywhere they may enter your home. For best results, use all six bait stations to ensure a sufficient supply for the ants.
Monitor placements regularly, but do not interfere with the pests or bait stations. Replace when bait is depleted. Complete control may take up to two weeks.
Once ants are controlled, replace the baits every 3 months to keep them from returning.

Terro has worked great for the last 4 years, new product suddenly does not attract ants at all.
Has the formula changed?
Based on this springs experience, I would say do not purchase this product!
I had those tiny ants practically *swarming* my kitchen counter - a knife my husband left out was covered with them. Put out 4 of these ant baits. By the next morning nearly all the ants were gone. This hairnet every spring, and this is, by far, the best product I've used.
Unbelievably fast acting! With spring here, we started seeing ants everywhere and it was driving my husband and I crazy. He was running around the house vacuuming them up with our handheld vacuum! He looked up best products to kill ants and this is what we found. We ran out and bought some, put them out and went to lunch. Came back of course there were a lot more around the bait and he wanted to vacuum them all up and I told him you need to let them go back to the colony and kill the rest of them! By the next day, the ants were gone, I mean, seriously all gone! We’re leaving the bait out for a little while longer just in case, but what a great product!
I just don’t know what we would do without this product. We use each year and thought for sure it just would not work against a huge storm climbing up the inside porch. We had to leave it for 3 days but this morning there are just a few very slow ants remaining.
Terro used to be an amazing product. You could put it out and 10 minutes later, there would be swarms of ants surrounding the bait and within 24 hours or so, no more ants. I don't know if the formula changed or if it's now watered down (it is noticeably thinner), but the ants now are not interested in it. Don't waste your money. It's not effective like it used to be.
When I first bought the clear traps there was a ramp for the ants to climb into the trap. Now that you've changed the design, they will not go in. I purchased the ones that you can stick on walls but opening it makes no sense because the liquid just comes out. I used to tell everyone about your product but I can't any longer. Why did you stop making the granules? They worked perfectly on my ant problem

I have been a believer in powdered sugar and Boraxo powder mix outside for years; BUT, this Terro liquid bait is amazing how fast it eliminated the colony(s). It was like a swarm appeared only 8 hours after placement on their trail. 48 hours later, all activity was GONE!
We have had sugar ants in our condo for the last few years, and I tried unsuccessfully to use a number of products to get rid of them.
I bought the terro liquid Bait trap, set it out, and within an hour or 2 there were a lot of ants crawling all over it with ant trails coming and going, and the next morning every ant was GONE.
I have some unopened baits from last year that I would like to use but they have turned an amber color. Will they still be effective?
Question by: Susan on May 19, 2024, 8:41 AM
TERRO® Liquid Ant Bait is typically a clear liquid. Sometimes it will turn an amber/brownish color. The good news is as long as it is in a liquid state it will still work. It is only when the product begins to crystallize or harden that it is no longer effective.

Are the liquid ant baits safe to use if we have dogs?
Question by: Colin on May 7, 2023, 5:27 PM

Do I clean area before or after baits in basement?
Question by: Sharon on May 8, 2023, 4:30 PM
Once ant activity has stopped, the area can be cleaned with mild soap and water if desired.
Answer by: Susan (Admin) on May 9, 2023, 11:43 AM
I have set a few baits over 1 week ago and they still keep coming. They are in a bedroom without any other food source. When will they stop?
Question by: Barbara Weimar on May 4, 2023, 11:26 AM
It can take up to two weeks to eliminate a colony. If you are still seeing ants after this time, it is possible that you are dealing with multiple colonies, or an extremely large colony.
