Product Description:

TERRO® Outdoor Liquid Ant Baits attract and kill common household ants.

To use this outdoor liquid ant bait, simply place the pre-filled, ready-to-use liquid bait stations outdoors in areas where ants are observed and secure the baits with the stakes provided. The weatherproof outdoor ant baits prevent the liquid bait from drying out, providing the ants with a continuous supply of food, day and night. Ants typically follow defined trails from the nest to food or water. Placing the outdoor ant baits close to these trails will improve control.

How Does This Outside Ant Control Work?

The key to successfully controlling ants is to lure worker ants – those that you see marching about in plain view – to the sweet liquid ant bait, which they will consume and carry back to share with the rest of the colony.

While the active ingredient in TERRO® Outdoor Liquid Ant Baits will ultimately kill the worker ant, this outdoor ant bait interferes with the ant's digestive system and works 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 outdoor ant bait stations and deliver enough bait to the rest of the colony. This is the only way to get rid of both the ants you see and the thousands you don’t.

    Forget about an exterminator By BibiT (Greer,SC)

    Don't waste time with exterminators. I had a national exterminating company at my hour 5 times in 2.5 weeks trying to get rid of my ant problem. They were everywhere in my kitchen and bathrooms. I called an exterminator friend of mine and he told me I needed bait for them to take back to the nest. Now mind you the national exterminating company did use a bait, but it did not work. I turned to the Internet to find ant bait. I found Terro. I bought 2 packs of the prefilled bait containers. When I tell you the number of ants that came out was scary, I mean really scary. It looked like a horror movie. I left the bait out until there was no more ant movement. Most of the reviews I saw it took about 2 days. However, it took a week and a half before I saw no more movement(we had a bad infestation). In fact I had to go back and buy some more bait traps because the originals were full of ants that ate themselves to death and died before they could take the bait back to the hive. Don't disturb the bait. I know it is tempting to kill the ants you see, but don't do it. This stuff is great! As a matter of fact, we saw some more ants crawling our chimney outside. We set the traps outside and in 2 days all the ants were gone. Why pay a $95 initial payment and sign a contract for $65 a quarter for a year when you can pay less than $15 for 2 packs of Terro and get the job done. Highly recommended!

    Amazon Review By Inna Tysoe

    All we could find for ants in our local stores were Raid ant baits for indoors. And we did need something for ants. Some ants got into the kitchen through the wall but we managed to snap those early with spray. However, we do have a LOT of ants in the garden and they seem to be patrolling various areas around the house. The Raid baits seem to have mostly done its job but it has been weeks and there are still the odd dwindled patrol. We recently got these Terro outdoor baits from Amazon to try. First thing I noticed was that they were quite large and so looked a little intimidating because I worried about my dog getting interested in them (he wasn't). They are simple enough to set up and place. They come with a pair of stakes for staking to the ground. When packed for storage, the stakes are a locking mechanism wedged between the actual bait and the platform base. You have to remove the stakes and twist the bait container which screws down and is pierced letting out the liquid bait that fills the platform base leaving a couple of small slits for the ants to enter. That means it's not easy to open or activate a bait by mistake. Since we had already mostly gotten rid of the ants at the front of the house, I used these to deal with the ant run near the patio door at the back of the house. This seems to be a large ant colony since the line of ants spans a distance of some 30 feet from the wild strawberries around the outside edge of the concrete pation and up to the house by the patio door. I placed a Terro bait there. Like I said, these baits are larger than you might be used to, so you can't always get them right on the marching line and since ants seem to like following along edges I was a little concerned they wouldn't work. It took about three hours before I noticed a steady stream diverted from the main run to the bait. So they definitely do seem to like the bait. Later on in the evening I checked and there didn't seem to be many ants visible which was odd. Thinking I might want to turn the bait around and re-stake it I started to remove the stake and ants came swarming out of the bait. So I decided to leave it and see what happens. Approximately 24 hours later, the number of ants was severely diminished. There are only a few stragglers marching along the old route and maybe a handful climbing over the bait. On the third day not much change, just a couple of stragglers. But no long lines along the edge of the patio to the house. At the front of the house, the Raid baits have severely reduced the number of ants but there are still the odd straggler or two-and that took almost a month. The Terro outdoor bait seem to have a huge impact knocking out a significant volume of ants in approximately 24 hours and, according to the instructions, it's supposed to work for three months. I'm very impressed.

    Q.Will the bait stations rid a heavy infestaion of argentine ants on about 2 acres; if so about how many stations should i use?
    A. Yes, TERRO® Outdoor Liquid Ant Baits are exactly the product we recommend for large outdoor invasions- including Argentine ants or crazy ants. With 6 baits stations included in the box, you'll be providing 6 oz of liquid bait. Which is perfect for large colonies that can drain a bait station very quickly. As a general rule, we recommend placing bait stations every 10-15 feet around your home. To be most effective, see if you can find where the ants are entering your home and place bait stations along their path. Even better, if you can find where the colony is located and place a bait station in that area.
    Q.What is the difference between the Outdoor Liquid Ant Bait Stakes- T1812 and the Outdoor Liquid Ant Baits- T1806? Both appear to perform the same function but utilize a different form.
    A. You are correct, both the Outdoor Ant Baits and Outdoor Ant Bait Stakes work in the same way, providing liquid bait that worker ants take back and share with the colony. But there are a few differences: Placement- The outdoor stakes are meant to be staked around your house and along ant trails, while the outdoor baits can be staked but also have a flat surface that can be used in garages, decks and patios as well. Colony Size- The outdoor baits each contain 1 oz of liquid (6 oz of bait total in each box). They will be a big advantage if you’re fighting a large outdoor colony or multiple colonies, that drink up and empty the bait very quickly (such as crazy ants or Argentine ants). Ease of use- The outdoor stakes are extremely easy to use, just place the stake into the ground and snap off the bait pack tab. High Temperatures – The outdoor baits are also ideal for high temperature regions where the liquid bait may evaporate quickly.
    Q.Will the liquid ant bait kill carpenter ants?
    A. Our liquid ant bait is made up of three main ingredients, Borax, sugar and water. This combination works to attract sweet-eating ants on the hunt for a food or water source. Although it is not their primary diet, carpenter ants do occasionally feed on common sweets such as syrup, honey, jelly, sugar, salt, and fruit and would be attracted to the sugars in TERRO® liquid bait during these times.

    More About Ants


    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 several TERRO Liquid Ant Baits on my deck 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.
