TERRO® Liquid Ant Killer

When you have a bug problem, you want to ensure your efforts are as simple and effective as possible. TERRO® Liquid Ant Killer uses borax to kill the ants you see, as well as the ants you don’t see. It works by allowing the forager 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. For your convenience, the packaging conveniently comes apart to allow for easy placement.

Ant Killer
 
Eliminate Ants
How Does Liquid Ant Killer Work? Since this is a bait, initially you will see more ants – but don’t worry, this is a good thing. As ants forage for food, they are easily attracted to the sweet liquid. After finding the bait, worker ants consume it and leave behind a pheromone trail leading back to the colony. This trail lets other worker ants know where the newly discovered food supply is. This is why you will see more ants in the beginning.

Meanwhile, the active ingredient, borax, is slowly interfering with each ant’s digestive system, ultimately killing them, but leaving enough time for the ants to go back and share the dose with the rest of the colony. This slow kill is necessary so that foraging ants can make several trips to the bait, allowing you to get rid of both the ants you see and the ants you don’t.

 

Where to Place Liquid Ant Killer

Place TERRO® Liquid Ant Killer near ant trails and other locations where they are numerous. Apply the baited cardboard tiles on the edges of sinks, tubs, windowsills, under food cabinets, along floors and baseboards and in corners. The more bait placements, the better! Be sure to leave the ant killer undisturbed while the ants are actively feeding on it.

Where to Place Bait
 
How to use
How to Use Liquid Ant Killer TERRO® Liquid Ant Killer is very easy to use. Before placing the ant killer, be sure to remove other sources of food, such as crumbs, sugar and grease spots to prevent attracting them elsewhere. Do not place where you’ve already sprayed insecticides, as the pests may avoid the ant killer.
  1. Tear the "PLACE TERRO® HERE" cardboard tiles from the packaging along the perforated lines. Then, apply drops of the liquid ant killer directly from the bottle onto the smooth side of the tile. you may also substitute with small pieces of paper, cardboard or foil.
  2. Place the ant killer tiles on a flat surface near signs of target pests. Place additional tiles anywhere they may enter your home. Heavily infested areas may require additional placements.
  3. Monitor placements regularly, but do not interfere with the pests or bait. Add more liquid if it goes dry or simply add more tiles to ensure there's always a fresh supply for the ants. Depending on the size of the ant invasion, complete control may take up to two weeks.

best ant killer around!!!!!!!!!!!!!!!!!!!!!!!! By joy

I have used terro for years. its the best thing since sliced bread. you do have to be patient. use it and wait about 4 days. if you see more then use more terro and they will eat it and take it back to their colonies and eventually all the ants will be gone. just give it a try. I did and I love it. I would never use anything else.

Was real skeptical about buying this item... By Marc

It seems all I have been doing is feeding these little black kitchen ants for over a month now and there are no signs of them slowing down. I've used up a quarter of the bottle so far and the results are nothing. I get about the same amount of ants everyday until the clean their plates and then off they go until I fill their buffet again. Not real pleased with this stuff at all.

when to stop using terro By kathb1120

i have what are called thief ants, i found out they love butter! i put a little dab of butter on aluminum foil than the terro liquid around it.....the ants are loving it. it's been about 2 weeks, the numbers are dwindling, for now.. my question is....when do you stop using terro....when you don't see ants anymore or would that be chancing it?

Response From Terro®
Jules : Consumer Relations Representative

Hi there!


We recommend removing baits when you know longer see them running around stealing anymore butter. If you begin to see a few after that, you can either eliminate them with a contact killer, such as TERRO® Outdoor Ant Killer Spray, or place your baits back down again. If you have anymore questions, we are always happy to help at 800-800-1819 x 458

Works very well By Do not have one

I have used this product for years and it has always been great. This time the problem was more persistent and it included some small black ants. Terro sent me a fresh bottle of the food and it finally worked after about two months. I always place a few drops on a piece of aluminum foil. They are attracted to anything shiny. Thanks for your help.

My go-to ant killer...no home should be without it By greg21

No home should be without Terro Ant Killer! I've been using it for 6 years now, & I won't use anything else. Before using Terro, I used to use Raid ant spray & Combat ant baits, but they didn't work as well as Terro does, b/c the Combat baits didn't work period & the Raid spray only killed the ants I could see & not the ones I couldn't see. Terro is better than Raid & Combat b/c it's liquid Borax, so it's sticky & sweet, which ants are attracted to. If patience isn't a virtue of yours, then Terro probably isn't for you b/c it's a slow-kill formula; the scavenger ants take it back to the colony and pass it on the queen ant, who passes it on to the rest of the colony, so it'll take some time for the formula to wipe out the colony depending on its size.

Why different this time By Dee

Used in the past worked great this time no, ants still eating this and getting inside the package this has been a few weeks used two packages, small black ants move quick.

Response From Terro®
Jules : Consumer Relations Representative

Hello Dee,


If you find that the ants are not interested in the ant bait, it may be that the ants are not interested in sweet treats at the moment. We recommend adding a contact killer, like TERRO® Carpenter Ant & Termite Killer, to your ant control plan. For any questions feel free to contact our Customer Relations Team at 800-800-1819 x 458

Non-effective By Joan

No, this product did not do the trick. It left big sticky globs wherever we put it and did not stop the ants from invading our home.

Q&A
Q.Does Terro kill big black ants?
A.

This product will effectively eliminate ants that are attracted to sweet baits.  

Q.We have been putting the liquid bait out on our kitchen windowsill and in our bathroom for a month now. (We're on our second bottle.) We keep refreshing it and the ants keep coming. Are we just attracting them or should we stop?
A.

In the beginning, more ants will flock to the bait station, but since you have been seeing them so active for over a month, you may have multiple colonies. Consider treating the outside of your home using products like TERRO® Perimeter Ant Bait Plus.
Contact killers like, TERRO® Outdoor Ant Killer Spray can also be used to treat window sills, door openings and other areas you suspect ants are entering the home.

Q.I noticed when I first opened the Liquid Ant bottle and placed it near ants, they were super attracted to it. But after several weeks, I used the same opened bottle and placed liquid near other ants, and they were not at all interested in the liquid - they went up to it and moved on. I kept the bottle in a cool dry place with the cap on tight. Does this liquid lose some of its attractant after the bottle is opened and stored away for awhile?
A.

This product does not lose its effectiveness as long as it stays in liquid form. In some cases, ants can crave different types of baits at different points in their feeding cycles. If this occurs, we recommend trying TERRO® Ant & Roach Baits. This product will attract those ants that crave sweet baits, and those ants that may crave protein-based baits.

All About

Ants

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.

More About Ants

FAQs

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.
