Terro® Liquid Ant Baits

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 Baits Work

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!

Where to Place Liquid Ant Baits
Easy Open Tab

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.

  1. Hold the bait station firmly with bait pack tab facing up. Break off the tab being careful not to spill the bait.
  2. 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.
  3. 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.
  4. Once ants are controlled, replace the baits every 3 months to keep them from returning.

I live in Metter Georgia.
Jul 8, 2024
I live in Metter Georgia. The ant capital of the South. It took one hour for the ants to find this bait and you would not believe the trail going from the ground onto my porch to the bait. They are eating it like candy. My only question is, why are they putting debris inside the trap? Anyone?

Jun 20, 2024
I set out one trap and it worked great but when I set out another one I couldn’t believe my eyes. The opening was plugged with debris and trash like the ants plugged it so other ants couldn’t go in. I know the ants can’t be this smart can they?

I love this product.
Jun 14, 2024
I love this product. It works extremely well and very fast. Had used it for years and will keep coming back forever. I tend to have more success by spilling a drop or two out of the container near the ants, to draw them towards the container. Left the traps out this morning, in a few hours there was a lot of activity at the baits, and by the time I got home from work every single ant was gone. Not a single ant dead or still walking around. Thank you Terro for being a legit product that isn’t very expensive

These work GREAT!!!
Jun 11, 2024
These work GREAT!!! You really gotta trust the process. Resist the urge to kill or clean lines of ants. Let them get the bait & go back to the colony with it and pretty soon, no more ants... maybe the random straggler walking in circles. These baits have 100% gotten ants completely gone from our home in a matter of 1-2 weeks. No more ants. It's cleaner if you can find where they come in, for us its the kitchen window. Set them up there and they just come in & out. Or even put one of the outside bates in the ground. But the inside ones will get the job done. 5 stars.

May 27, 2024
I have never written an unsolicited review but, this worked so I felt compelled to endorse. I have fought, and lost a Spring ant problem for YEARS. I tried the home remedies, oils, corn starch, etc…. I tried other commercial products too. Was going to call an exterminator and decided to try the liquid traps. Oh my gosh! They work so well, I couldn’t believe it. I set out a couple of traps. The first day the main trap (none even made it to second trap) was black with the little pest. I replaced it and it is still working great. I have not seen ONE on my counter (which would gross me out and cause me to bleach my counter). Please don’t discontinue this product. I love it and love checking to see that they go straight to the trap and STAY THERE.

Swear by this product
May 20, 2024
My parents swore by Terro when I was a kid. Now second year I notice ants outdoor on my patio near my door. I set up a bait and about 50 ants swarmed the bait carrying it back to the nest which I don’t know where it is. Love this product! Thanks for keeping me ant free

Best liquid ant bait!
May 10, 2024
Best liquid ant bait! Our local store ran out of Terro, so I had to get the Black Flag version of the liquid ant bait. It sat there for almost a week in their path untouched. Our store finally got Terro in stock. Within an hour of being placed, the Terro was packed! There's no reason to buy any liquid ant bait, but Terro.

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
We recommend placing these bait stations out of reach of any pets.
Answer by: Susan (Admin) on May 9, 2023, 11:19 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.
