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 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!
Review Rateeasy to use
Well, the ants LOVE this stuff. They literally line up to eat it. It's easy to see it being used by them and easy to use. The solution is thick and doesn't run. A little goes a long way. Thanks Terro!
Review RateCarpenter antsI had a large nest of carpenter ants in my tree. I could not believe the activity of ants moving up in down the tree at night. There were hundreds of them. I bought some of the liquid gel and made a continuous line around the trunk so they would have to walk through it. Within a minute all the ants were consuming the terro gel. Next day. Not a single ant. I was shocked at how well this stuff works.
I put this out at the first sign of ants inside my house this spring. It took 4 days to be ride of the ants for the spring and summer. I will for sure use it again next spring if I have to. I would say use this. The price is right and the results are GREAT !
Review RateRevenge on the Black AntsI bought liquid any bait and very happy I did. I had black ants crawling all over my new trex board deck. I had previously tried other brand ant granules and they did nothing. In fact I watched the ants actually walk away from other baits. However the liquid bait from Terro they swarmed to. I strategically placed drops between the spaces of the deck and fasteners so ants could easily access but not humans. I baited for 3 weeks and reapplied after rain. This stuff works. I wasted a ton of money on other products. Ants are now gone with Terro Liquid Ant Bait.
Review RateGreat Product at Excellent Price
I had 4 large outdoor colonies. Infestation of two trees and two good colonies going underneath my house. I purchased for $3 a pack of 4 liquid bait containers. Checked on bait spots in a couple of days making sure all was well. Needed to replace baits 3 times (the 3rd time I poured it onto our lava rocks). Within 3-4 weeks both colonies going under the house were gone. Still some occasional (slower) ants at trees so just left more out there to finish those off and to prevent new colonies from starting. I'm totally impressed. Wish I would have used this years ago. Fifty six year old mountain woman.
Review RateSudden death for antsI've used the Terro liquid antkiller for years. Whenever I set out a few dabs ants are soon fighting with each other to get their fair share. Astoundingly more effective than all the more expensive fancy treatments.
Review RateLove itIntoduced to this product when it first came out while working in pest control business. Ot has been the best product out there for safe indoor ant control. Highly recommend
- 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.
