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.

Be gone ANTS!!!! By firehawk

Every year at this time these pesky ants come in and can wreak havoc everywhere getting in sugar creamer etc. This stuff rocks and gets rid of all ants. I am thinking they take back to nest where other ants devour the taste to succumb to their ultimate death.

Great Product With Quick Results By Al

This was recommended by an employee at the hardware store and he was right. We had a ton of ants show up one afternoon sneaking into the kitchen through the overhead stove vent. Put one dose out on the counter and another inside the vent outside and 24 hours later the ants were gone. It is true that a ton more will start showing up once it’s out but let them eat. They’ll be gone soon enough.

Terro works! By JJ

At the beginning of warm days here in Virginia and after the mulching of my patio garden, I saw ants near the front door. I had some Terro that had been around for years - it was dark brown and thick. Nevertheless, I was able to squeeze some from the bottle and put it down. I didn't know if it would still work. The ants were gone the next day. I immediately bought another bottle for next year. Thanks so much for a product that works!

Great stuff works wonders By Gobucks88

This is the best ant bait on the market. Every year around this time we get little black ants In our kitchen. Couple drops of this stuff on the cardboard tray and those stupid ants are lined up for some liquid death. Can’t get enough of this stuff. Just make sure your area is clean so they aren’t tempted to eat anything else

Ant Pinic Surprise! By JIm

Very, excellent product!! Had ants on my kitchen counter and coming from the window sill.. Amazing they can squeeze in a window that is tightly shut! I used this product and within 3 days they were gone.. At first they brought their friends to eat the tasty delight, but paid the price later!! I will say though that if some of the syrupy ant bait is left too long in one spot, it will dry and become a little difficult to scrape off. But other than that, I will buy more for this Spring!

It’s like ant crack. By Dala

Amazing, tried Raid traps and the ants wouldn’t come close to it. Removed the bait from the container and the ants would crawl right over it. Tried Terro and it’s like ant crack, they went ballistic for it and about two days later not an ant in sight. Would recommend this to anyone.

Q&A
Q.How long is liquid Terro good for?
A.

The liquid ant bait does not have an expiration date; as long as it is in liquid form it is still active. However, we recommend replacing the bait after two years to keep it fresh.

Q.Is this product harmful to cats if ingested?
A.

The main ingredients in this product are sugar, water and borax. We recommend providing this information to your veterinarian for medical information/advise.

Q.If I use this product directly on the wooden floor, will this damage the floor? I used this to seal the gap that the ants are coming from and I have no more ants in my house. But would this damage the floor?
A.

We do not recommend placing this directly onto a floor. Instead, the bait can be placed on the included cardboard squares, or even a piece of tin foil.

The species of ant determines whether they live underground, in mounds built at ground level, in wood structures or in plants or trees.

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.
