TERRO® Ant Killer attracts and kills all common household ants. The liquid ant killer is specifically designed – using the active ingredient Borax – to allow worker 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.
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. Baiting enables you to get rid of both the ants you see and the ants you don't.
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.
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.

Review RateThank you!
Like all the other reviewers previously stated, don’t think twice about buying this product, do it ASAP. Will get the job done and fun to watch the ants engorge themselves to doom! Without a doubt the best $4 I have ever spent and I don’t have to worry about toxicity with the kids or pets. Buy it!
I think that hundreds of ant must have invaded our crawl space before they appeared in our kitchen. I refuse to use toxic products, and although it's taken quite a long time to get rid of all those ants, we're finally down to just a few, thanks to the Terro liquid we've been using.
Review RateNothing works better, NOTHING!
Had an older mobile home in Arizona that ants had literally taken over, filled sections of the outer wall from bottom to top plates, as well as a basketball sized crowd of them hanging under the kitchen sink. Tried everything we had on hand, nothing seemed to work except wasp spray, but ran out of that real quick. 2:00AM, no stores open, getting panicked, they're in the bed, shower, everywhere but the PANTRY! Finally got to the store when it opened and was told to use the TERRO liquid bait. Did that, amazed at how quickly the ants congregated around those drops and began consuming it all. Couldn't believe it, but true! Just a few hours later, they were GONE! ALL OF THEM! Now that we're living in Oklahoma, I've stocked up with plenty of it and use it religiously!
Review RateThe nuclear option for ants
We had a colony of ghost ants get inside our apartment in Hawaii. Over the course of a week they had made it into the kitchen and into 2 bedrooms despite our attempts to kill them with things like raid or other traps. I was starting to lose my mind because they were getting everywhere. I realized at this point we had made one colony into at least 3 through "budding". We went out and got a bunch of stuff, and this tiny little bottle of Terro Ant Killer looked like a long shot. i used the little cardboard plates and set out a bunch in all the areas we saw the ants, and watched a movie with the family. About a half hour later I went to see if there were any ants and HOLY GOD. They were all over this stuff. They had lined up around the edges like wildabeast drinking from the last waterhole in the Africa. I thought we had a few hundred ants, but there must have been a thousand. I checked, and all the other traps were in a similar state. I started to laugh out loud like a madman. In 24 hours, it was all over. the bait was vacant except for about a dozen ants who got stuck and drowned. We haven't seen a single ant for over 3 weeks now. The most difficult thing about this product is watching the ants go nuts with the bait and resisting the urge to kill them when you see it. Its disgusting. But do like I did, laugh like a madman and rub your hands together. They are already dead, and if you leave them to it, they will spread the pestilence to all their disgusting kin. If ants ever become sentient, they will put Terro on trial for crimes against antkind, because this is ant genocide in a bottle.

Review RateThe Best
I can't express how great this stuff works. We tried everything, but nothing worked. I friend referred this to me and it completely got rid of all the ants in about 5 days. Best product on the market.
Review RateThis is great stuff
This is some good stuff. I have tried everything before using Terro. Terminxx came out to spray and made matters worse. Prior to Terminxx I would only see a few ants. We could barely eat at our kitchen table without the ants wanting to join us after Terminxx's visit. I would mop with vinegar and bleach every night with also leaving down boric acid. After using Terro it took about 3-4days before the ants left. I used outside terro baits also after tracking where the ants were entering our home. Try it give it at least 5 days!!!
Review RateAnt Magnet
Terro’s ant control product works as advertised but you need to be patient. When you find a trail outside place any one of the bait stations near it and make sure it stays replenished with bait. As long as there’s bait the ants will continue to visit until that colony is wiped out. A word of caution - don’t buy to much at one time - I made that mistake and found out to late that the product has an expiration date that’s not mentioned on the packaging and I ended up discarding several unopened boxes of outdoor bait stations and three bottles of liquid bait.
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.

- 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.
