TERRO® Ant Killer, TERRO® original 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, 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. The product 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 the product 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.
This is the only way to get rid of both the ants you see and the ants you don’t! While the active ingredient in the bait 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 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 also may be substituted.
Place the product 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 then disappear.
Since invading ants usually have outdoor nesting sites, it often helps to put the product outside, 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.

Review RateNot killing them completely
Well it is crack for ants but... I have been feeding ants the bait for almost 2 months. They disappear completely for about 2-3 days then come back full strength. This is some cycle...Response From Terro®Jennifer : Consumer Relations Representative
We apologize for this experience. When a decrease in ant activity is seen, we recommend removing and disposing the bait to prevent scout ants from finding the product.

Review RateI tried everything
I never comment but have to give credit where due! I have tried every ant poison on the market to kill the little black ants in kitchen. if i use a spray it only deters them from that area and they pop up somewhere else...very frustrating....years i have put up with this i have even had exterminators but only lasts a couple of months or until the eggs hatch and there back! I have been Using Terro for a week now and have seen the ants diminish quickly getting less and less everyday. Terro has the right amount of borax to allow the ants to get back to nest and feed the others, if you make yourself and add the wrong amount you will only kill the ants at the dinner table and they die before they can return...well done Terro
Nothing worked until I used your product. They were gone in a day! Thanks,
Review RateKills em dead
I have been invaded with sugar ants/ crazy ants. I have sprayed with biding it. Used powdered borax. Aerosol ant spray. Window cleaner. U name it I've tried it. NOTHING WORKS. Then I remembered my mom using Terro and how cool it was to see the ants go to it and gather all around and eat it. Then a few days later the ants were gone. Well hor some today. The lil buggers sre all around eating it. And I really want to kill them but I know I have to leave them alone so they will take the poison back to the nest . This stuff is great. I will never be without it in my home again

Review RateIt Works!
We were plagued by ants in our kitchen for a few years and nothing we tried worked. I read about Terro liquid ant killer in Southern Living magazine and immediately ordered it. We've had the traps out about three weeks now and haven't seen a single ant since, and this is their active season! Thanks Terro!
Review RateWorks like magic
Excellent excellent stuff. My husband brought home a few of the traps and said someone gave him these and said they are the best for killing ants. We put out a trap and within an hour the thing was filled with ants lining up 3 deep to drink at the trough...by evening, the bait trap was empty and then.....amazing! Ants gone!!!. So let it do its job, set it down, watch as it attracts all those little pests, watch as they gorge themselves, run back to their hideouts....knowing the whole pack of em are getting a good dose of the stuff too and presto, no more ants. LOVE THIS STUFF.
Review RateGood stuff
Works every time ..they are on it like white on rice
- 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.
