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.

Every Spring I have been ...

Jun 14, 2025
Every Spring I have been battling the demise of these very small ants, to no avail. Tried Raid, tried all kinds of things; they all did nothing. These small ants would be everywhere in my kitchen, and I am a "clean freak." This had me in tears until my neighbor told me about Terro Liquid Ant Baits. Worked withing 24 hours and I only put down two ant baits near the point of entry. Inexpensive and positively works; very, very easy to use. I highly recommend!!

I’ve been using this ant ...

I’ve been using this ant bait for years. The good news is it’s effective. The bad news is the container design. The end doesn’t twist off, no matter how careful and persistent you are. Trying to remove it results in a mangled mess. Also on two of the bait stations the liquid leaked out of the open end despite the floor being perfectly level and clean up was a pain in the you know what. Please please please redesign the ant bait stations.

SO. MANY. ANTS!

May 18, 2025
SO. MANY. ANTS. They are tiny, but there are so many of them! Grabbed a couple of these liquid ant bait traps, put them on both sides of the foyer and sat back and waited (a little impatiently I might add). I checked them frequently and started to get disappointed that nothing seemed to be happening. Went off to work and when I returned about 7 hours later I stopped in my tracks. I was equal parts disgusted and satisfied at the hundreds of ants that were swarming the bait traps and moving to and from the traps in a single line! I left everything alone and went to bed. This morning, they are GONE! All of them (except a few that are stumbling around)! Could it be this easy and this effective? I don't think I've ever been so happy with a product!!!

Undoubtedly, the most effective anticide I have used.

Undoubtedly, the most effective anticide product I've used. After an infestation under our upstair's bedroom floors, the Terro Ant Bait packs with sodium tetraborate (Borax) performed, as stated. Within three to five days, the ant colony ceased returning to any bedroom area. This product stopped ant colony presence in a 17' X 33' master bedroom. Will start deploying your product in other areas of the house when the need arises. A large thanks to Terro.

This product was a recommendation on Reddit. I placed two near ant sites and within an hour they were going inside. I checked this morning and there were only two ants inside one and the other had zero even though there were dozens before bed. Have the ants figured it out?

So disappointed in new product. Old design/product worked great. Literally no reason to change it. Current product doesn't work at all. Waste of money.

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 ...

Apr 26, 2025
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!

Apr 25, 2025
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!

Q&A

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.

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
We have an indoor cat. If he checks out the bait is it safe.
Question by: Jim Rogers on Jul 16, 2025, 10:34 AM
Hi, thank you so much for your question. You can use the product around pets, but if your cat digests it, please take them to the vet immediately.
