TERRO® Ant Killer attracts and kills all common household ants. The liquid ant killer is specifically designed – using the active ingredient Borax – to kill the worker ant in two to three days, giving the foraging ants enough time to share the bait with the rest of the unsuspecting colony.
To use our best ant killer, simply apply the product directly from the bottle onto the provided cardboard squares and place near indoor areas where ants are spotted.
How Does It Work?
TERRO® Ant Killer is a bait product, so at first ants will come in large numbers, but they will soon disappear. This liquid ant killer is specifically formulated to allow worker ants to consume the product and survive long enough to carry the liquid ant killer back to the nest and deliver a dose to the rest of the colony.
Leave our at-home ant killer undisturbed while the ants are actively feeding on it. Be sure to eliminate all other food sources in the area. This will ensure that the ants aren’t tempted to eat anything but the deadly liquid ant killer – indoors and out.
This is the only way to get rid of both the ants you see and the thousands you don’t! While the active ingredient in our indoor ant killer will ultimately kill the worker ant, it interferes with the ant's digestive system and works just slowly enough that the worker has time to get back and share the ant bait with the rest of the colony. This slow kill is needed to allow time for the foraging ants to make several trips to the bait and deliver enough bait to the rest of the colony.
Directions for Use
Tear the "PLACE TERRO® HERE" cardboard squares from the home ant killer packaging along the perforated lines and simply apply the liquid ant killer directly from the bottle onto the square. Small pieces of paper, cardboard or foil may also be substituted.
Place this household ant killer where ants are seen, such as the edges of sinks, tubs, window sills, under food cabinets, along floors and baseboards, and in corners. Do not skimp on bait placements; the more bait placements, the better.
The key to effectively eliminating the ant infestation is to monitor the placements and ensure there is always a fresh supply of TERRO® Ant Killer for the ants to feast on. Depending on the size of the ant invasion, complete control may take up to two weeks.
Resist the temptation to interfere when the ants come in droves — your patience will pay off as you watch your ant infestation dwindle and then disappear.
Since invading ants usually have outdoor nesting sites, it often helps to put our best ant killer outside the home, close to where ants are found entering the structure. Ants typically follow defined trails from the nest to food or water, so placing the ant killer close to these trails will improve control.

1TERRO® Liquid Ant Killer is rated out of 5 by 37.Rated 5 out of 5 by Roger from Terro ant killer Put it down two days ago , wow no more ants , thanksDate published: 2015-08-19Rated 4 out of 5 by jackie27 from After a few hours seeing fewer ants. I have been having an ant invasion problem through-out the summer coming through the window sill. The apartment where I live sent out a pest control company to address this problem, what a joke. On their last visit the pest control worker set out versions of their baits, however removed them due to the baits were filled with ants. After removal of the ant baits he put down a liquid gel which lasted about 13 days, after placing the stuff believed to be the point of entry, very disappointed that the Black ants began to resurface in full force. Needless to say, I freaked out after having a hectic day to began with. I went to the hardware store and purchased Terro baits as well as their liquid ant killer, it haven't been a full 24 hours yet, but seeing remarkably less ants. I will follow-up with a post about Terro brand and it's effectiveness, hopefully to give it 5 stars, and indicate if I will remain a devoted customer or not.Date published: 2015-08-15Rated 5 out of 5 by Elvis from Fast and Effective I been using this in the liquid form for a few years now....As soon as the ants start showing up....I feed them....it is like a magnet to them....then...BYE-BYE-..the numbers start dropping off....So easy to use....NO-Mess....Thanks...Date published: 2015-07-26Rated 5 out of 5 by SusanConstant from Product Lives Up To Promise! I purchased Terro from a hardware store as it was cheap and the expensive products I purchased did not work. I was tired of paying for ineffective traps, sprays etc. and in my state boric acid isn't available. I was hopeful in that Terro is syrup like. Beyond that I didn't expect much...was I wrong! Terro worked in minutes. The ants literally came out of the woodwork, swarming the bait. They bring it back to the nest and no more ants. One side note: I lived at the beach and we had a recurring problem but I was dealing with new nests. After several uses it seems the ants got wise and began to avoid it but I never had a large scale problem with ants again as we'd see a handful and that would be it, almost as if the ants decided dealing with Terro wasn't worth it. Hopefully Terro will not play corporation dumb and improve a product that needs no improvement.Date published: 2015-07-22Rated 5 out of 5 by Johnny from Fantastic Solution! I've been battling ants since I got my first apartment in 1977. Using the typical ant sprays over and over again with just temporary results at best...more ants just keep coming. Recently I discovered Terro Liquid Ant Killer, and wow, a few drops for few days and the ants are gone! My first application was in the kitchen where we typically have a hard time finding where ants come in. Not a problem. We put 2-3 drops near where the ants were most prevalent. As the drops dried up we added a few more (twice a day) for two days and we haven't seen ants in the kitchen since, and that was about three weeks ago. I'm now using the drops at our office where during the summers there is a huge ant invasion. A few drops in a few places for a few days and once again the ants are gone! It takes so little to do the job, and it is so inexpensive, this stuff is fantastic. Thank you Terro!Date published: 2015-07-21Rated 5 out of 5 by liquido from Did The Job Im an expat living in the philippines..I had a friend bring back a bottle of Terro because of some small pesky ants i had on my kitchen counters and other area's..I followed the directions on the bottle and the ants are completely gone after a few days of taking the product back to there nest..Im very pleased....Date published: 2015-07-19Rated 5 out of 5 by Brenda from Works Like A Charm! I bought some Terro at the recommendatuion of a friend.Date published: 2015-07-02Rated 5 out of 5 by CKalbach from These work well. My wife and I have been using Terro ant baits for about two years now to help control ants in our Southern California home. We have a recurring problem in that when the the weather gets hot and dry, the ants want to move in and live with us. We were constantly battling to keep them out of the kitchen. We've found that putting a few traps in out of the way places and allowing as many ants to feed from the traps as want to has almost completely eliminated the kitchen invasions. In at least one instance, we believe that using these traps wiped out a nest inside the walls of our home. We bought the traps first and reload them using bottles of liquid ant killer. I keep several traps and bottles on hand for when the weather turns warm.Date published: 2015-06-26
my Terro is getting turning solid overnight, is this common?To help prevent the liquid from drying out, we recommend adding a few drops of fresh liquid each day. This will help ensure that the product remains liquid and the ants will be able to consume the bait.Date published: 2015-08-08

When liquid dries after a couple of days and ants continue to eat at it, is it still active, or does it have to be in liquid form to be transported and kill the colony?The bait should be replaced once it has dried. If it has hardened the ants are not able to consume it.Date published: 2015-07-01
why do ants use tiny wood chips to cover liquid terro? they started to cover it with dirt, tiny wood pieces after one day. I replaced with fresh ferro, they covered it again. It has been 5 days already and I still see ants.It is common for ants to place small material near the bait. They may be attempting to "hide" the bait. As long as the ants are coming to the bait they will consume it and share it with the rest of the colony.Date published: 2015-06-26

- All About
There are more than 10,000 known species of ants living throughout the world. Like other insects, they have six legs; each with three joints. Ants have large heads with compound eyes, elbowed antennae and powerful jaws. Ants are social insects that live in structured nest communities throughout the world. The species of ant determines whether they live underground, in mounds built at ground level, in wood structures or in plants or trees.
Why are ants always invading my kitchen, bathroom and laundry areas?
Ants are attracted to food, water and shelter. Kitchens, bathrooms and laundry rooms provide at least two of these conditions, making it an ideal haven for ants to congregate.
What’s the difference between liquid and gel ant baits?
It’s a little known fact that adult worker ants cannot digest solid food (bait). Their anatomy is designed for transporting and digesting liquids only. Solid foods must be carried back to the colony for additional processing by the larvae stage. Liquid baits exploit this unique physiology by making it easy for ants to transport the liquid bait back to the rest of the colony, including the queen, larvae and other workers.
I just placed TERRO Ant Killer in my kitchen and it’s attracting more ants, not killing them! What’s going on?
You have nothing to worry about! Initially, you will see more ants. As ant foragers look for food, they are attracted to the sweet liquid in the bait which they consume and carry back to feed to the rest of the colony. On the way back to the nest, the ants drop what it called a ‘trail pheromone’, letting the other ants know where the tasty food supply is. In turn, these ants follow the trail to the bait which explains why you initially see more ants.
The active ingredient in the bait interferes with the ants' digestive systems, eventually killing the ants within 24-48 hours after consumption. This slow kill gives the worker ants enough to get back and share the bait with the colony. Baiting is the only way to successfully wipe out the ants you see and the thousands you don’t.
