When you have a bug problem, you want to ensure your efforts are as simple and effective as possible. TERRO® Liquid Ant Killer uses borax to kill the ants you see, as well as the ants you don’t see. It works by allowing the forager ants to consume the product and survive long enough to carry the liquid back to the nest and deliver a dose to the rest of the colony. Complete control may take up to two weeks. For your convenience, the packaging conveniently comes apart to allow for easy placement.
How Does Liquid Ant Killer Work?
Since this is a bait, initially you will see more ants – but don’t worry, this is a good thing. As ants forage for food, they are easily attracted to the sweet liquid. 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 each ant’s digestive system, ultimately killing them, but leaving enough time for the ants 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, allowing you to get rid of both the ants you see and the ants you don’t.
Where to Place Liquid Ant Killer
Place TERRO® Liquid Ant Killer near ant trails and other locations where they are numerous. Apply the baited cardboard tiles on the edges of sinks, tubs, windowsills, under food cabinets, along floors and baseboards and in corners. The more bait placements, the better! Be sure to leave the ant killer undisturbed while the ants are actively feeding on it.
Where to Place Ant & Roach Baits
TERRO® Liquid Ant Killer is very easy to use. Before placing the ant killer, be sure to remove other sources of food, such as crumbs, sugar and grease spots to prevent attracting them elsewhere. Do not place where you’ve already sprayed insecticides, as the pests may avoid the ant killer.
Tear the "PLACE TERRO® HERE" cardboard tiles from the packaging along the perforated lines. Then, apply drops of the liquid ant killer directly from the bottle onto the smooth side of the tile. you may also substitute with small pieces of paper, cardboard or foil.
Place the ant killer tiles on a flat surface near signs of target pests. Place additional tiles anywhere they may enter your home. Heavily infested areas may require additional placements.
Monitor placements regularly, but do not interfere with the pests or bait. Add more liquid if it goes dry or simply add more tiles to ensure there's always a fresh supply for the ants. Depending on the size of the ant invasion, complete control may take up to two weeks.

I have used terro for years. its the best thing since sliced bread. you do have to be patient. use it and wait about 4 days. if you see more then use more terro and they will eat it and take it back to their colonies and eventually all the ants will be gone. just give it a try. I did and I love it. I would never use anything else.

When it heats up in Dallas, ants start finding their way inside. Every morning we'd find our kitchen counters crawling with 'em. Tried a few different products, but none worked until we put out a few Terro trays. Problem solved within a couple days. Super easy and effective.
Had a hundred or more tiny sugar ants on my kitchen counter. Tried the ant traps but they didn’t work for my ants. Bought the liquid Terro ant killer and followed instructions. They were flocked in to get some of that great stuff. Two days and they were no where in sight. I’ll never use anything else!!
All ants gone by 24 hours. Hundreds of ants swarmed the traps within an hour of being placed. Came home from work the next day, haven’t seen a single ant
My counters were crawling with so many ants so I tried this product by placing them all over my kitchen and watched them by the hundreds go to the stuff and drink it. The next day and I have not seen 1 Any and it's been 4 days now. I highly recommend this product it is by far the best
Amazing!!! For months I was at Battle with Tony little nuisance pest. After only one day of playing Terro liquid around kitchen the are Gone!! Haleighluyah
First I had those tiny ants by my kitchen sink, we've had a lot of rain and it always brings ants into the house. It is amazing how they flock to the Terro bait tiles. Now I have the big black ants - ugh. I took a few tiles (I had to make my own) put drops of Terro on them and BAM! covered with black ants. I live in the South so rain, humidity and heat are always here. I have a dirt cellar in my 120 old house, it attracts every bug living. These liquid bait tiles are the best. It is pretty gross when they swarm over the tiles to get at the bait. I hope it works for these big guys as it did for the tiny little ants. Great product.
Aside from working beautifully, Terro instantly has the little pests swarming around the bait instead of the pantry, counter, or whatever attracted them originally. It really is possible to “herd” the ants!
The tabs are too small. Difficult to place one drop in the center where it won’t spill over. If you need to place the bait on the tab and then slip it under the counter it gets messy. It is too small to safely lift and maneuver into place.. I wouldn’t purchase it again.
The liquid bait consists of borax, sugar, and water. We recommend keeping the bait out of reach of curious kitties. Any medical concerns should be directed to a veteranarian.

Terro liquid seems to harden over night. Does it need to be replaced daily?
Question by: Tom Maloney on Apr 23, 2024, 12:07 PM
Bait should be replaced once it has hardened. How quickly this occurs is dependent on environmental conditions.
Is there an expiration date on the bait? I can't find one on the box. Thanks!
Question by: Larry Stolte on May 8, 2023, 1:25 PM
As long as the bait is liquid, it will be active. We do recommend replacing it after two years to keep it fresh.

What if the ants come and you have put out fresh bait? Not fazzy them this time.
Question by: Walt on Oct 31, 2024, 8:26 PM
After you put out fresh bait, you will see more ants for the next couple days. They are taking the bait back to the colony, where eventually it will kill all of them. The more ants you see in the first couple days, the more effective the ant annhilation will be.

If this product comes in contact with skin, we recommend washing the area with soap and water thoroughly.
