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 RateHalts Ants
Twice this product has worked to halt sweet ant activity in my residence's kitchen.
Review RateGreat stuff I won't be without it on hand.
At risk of sounding like all the other reviews this stuff is AMAZING! My note of caution is to resist the temptation to want to kill all the ants that will appear on your counter but don't. I put Terro out in three or four spots along back of counter the first day I could not believe I had so many ants on the bait I could not count them. On day two there were still quite a lot day three were just a hand full. Today is now day four and I woke up to no ants. So Happy! If you have ants get Terro.
Excellent product! Ants that marched onto my kitchen sink were gone two days after application of Terro liquid!
Review RateHOLY COW ! ! ! No More ANTS ! ! !
Found TERRO online. It arrived in TWO days. I studied these microscopic ants to see what attracted them and where the main places were where they congregated. Mostly, they were attracted to dark places, water and food. I put the TERRO 2" below the edge, in a steady band, all around the inside a small plastic garbage can and put a banana peel, bits of hamburger, and some other scraps of food , then placed the can where the main ant traffic was. I also found TONS of ants under an old lamp. they climbed the electric cord and followed it into the lamp base, so I put TERRO on the length of the cord, on the hole into the lamp base, and just around under the rim of the lamp base so the Cat wouldn't get into it. In only 4 days, the ants completely disappeared from the entire house. Now I have FIVE extra bottles and 2/3 of the first bottle leftover. Thanks TERRO :o)
Review RateNot the first time I've turned to Terro
Terro is pretty good stuff. It's easy to see the ants swarming all over it, and in the past it's worked well for us. You should know the thick killer gel will ooze out and make a gluey mess of your floor or shelf or whatever, so be sure and set the gel traps on cardboard before leaving it out for the ants. Also, out of 4 different nests we've had to deal with (little black ants), 3 were wiped out by Terro, and 1 still had a steady trickle of ants coming to feed at it 6 weeks after being set out. It had killed a lot of ants, but not wiped out the source. Still, I turn to Terro when the weather gets rainy and the ants come in because the other baits don't seem to work nearly as well. And forget those stupid baits with the hole at the top - what a waste of money! The ants don't seem remotely tempted by those things! **Note - if you can see the place in the ground where the ants are coming in, try pouring boiling water in there. This is good cause you are not putting poison around your home (not good for you or other wildlife), it's free, and you get instant results! But if you can't find the source, or can't get to it, then Terro is the way to go.
Review RateReally like this product and cannot always find itIn winter and sometimes other time, we are inundated by ants of all sizes. This is the only product that eliminates them quickly. Sadly, we cannot always find the liquid variety which works best for us until I ordered it from you.
Review RateBest ant bait EVER!!!
I discovered an ant trail coming through my laundry closet into my food pantry. I tried some DIY tricks but it didn't work. I discovered Terro Ant Killer while at Walmart. I googled it to see reviews. After reading so many good reviews, I purchased it. IT WORKS!!! I was impressed how quickly it got rid of the ants. I'm a customer for life! Thanks Terro for such an effective product to eliminate the ant problem expeditiously. Now what about spiders? lol
I purchased this to rid my home of ants. Within days the numbers dwindled to almost nonexistent. I'm sure that in a few weeks, my home will be ant-free!
Review RateGreat product!
I bought this because I had ants in my car!! I don't know how they got in there, but I put a dime size amount of ant killer in the front floorboard, the back seat floorboard and in the back of my SUV. After just a couple of hours, ants were swarming all over the traps! I didn't even think there could have been that many in my car! I was tempted to spray them with another ant killer, but after reading other reviews, I resisted, and let them eat. I left the liquid in there overnight, and the next day they were gone! I left the liquid in for a couple more days to make sure they were all dead, but I haven't seen the first ant. I am very happy with Terro liquid ant killer!
- 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.
