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've used these for years. I always gotten excellent results. I prefer the old model because the new one is not easy to snap off.

Four and four-fifths stars rating.
Mar 27, 2024
Four and four-fifths stars rating. (one fifth equals one point of a star) Attracts and kills the ants, but the snap-off tab doesn't snap off. I've tried twisting the top off, mangling it and hurting my hand. I use scissors. Other customers have pointed out the same issue. Anyhow, not a biggie. I like the product because since I started to use it, I've seen significantly fewer ants on my kitchen counter. Ants are amazing creatures and it seems like they can sense a FRACTION of a single grain of sugar or drop of oil on a kitchen counter. I clean the counter and I would still see "explorer" ants searching my kitchen counter for nutrition; when I put the Terro traps on the counter I rarely see ants.

Mar 22, 2024
Last year I had what I call tiny sugar ants invade my pantry. They were coming in somewhere around the backside of the fresh air return from underneath the floor. I could not see the exact location of entry but I sprayed first all over with Raid after emptying everything out, next day still there. I then tried Zevo that didn’t work either so I went to Home Depot and got these Terro Liquid Ant Baits and put two of them out and the next morning they were all gone! I recommend them to everyone!

I just put these out so I can't say that they've done the job just yet. But it's amazing how quickly the ants were attracted to these. Immediate "swarm".

Jan 3, 2024
I feel that there are pros and cons with this one. I left it in my brothers window sill because he said he know a few would come in. I left the terro there for 2 weeks and after 2 weeks I finally decided to have a look at the progress. I found so many ants killed inside of it and around the terro so it def did work. But I also saw so many ants avoiding it and charging inside the whole room and some getting throughout of my brothers room and going into other rooms. I feel that I lured it inside with the terro; it may have killed a lot but there are a lot more ants coming from the window sill and swarming around now. Not sure what I should do.

Nov 19, 2023
They do attract ants like crazy. I’m not sure if they are taking the bait back to the colony but they sure are killing them on contact when they crawl in. Glad that these are clear so you can see the amount of ants killed inside the traps.

Sep 28, 2023
I just moved into a brand new construction house. Within two days I had a pretty big ant infestation in my master bed and master bathroom. Two really odd places considering I have no food in either area of my house. I put the traps out in those two areas as well as my guest room. Within 12 hours all the ants were gone. Unfortunately, although the ants are gone in those areas they are now in my office. I'm not sure why the traps didn't eliminate the entire colony when I baited those other three rooms. I'm guessing I have multiple colonies throughout my house. This last room is a doozie. Way more ants are in this trap. I'm hoping it's the last trap I have to put out. I'll hold my final star until then.

These things really work.
Aug 22, 2023
These things really work. I have been using for a few years now. You just snip off the top and lay it near where you see the ants. In a day, you will see tons on ants going in and out. You have to leave them be. Resist the urge to kill them. They will take it back to their nest and feed it to their family. I did recently get a odd color batch. I called the 1-800 # on the box. He explained why it was that color and assured me I could still use them. I highly recommend

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.
