Product Description:

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

To use, simply place the pre-filled, ready-to-use liquid bait stations outdoors in areas where ants are observed and secure 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 It Work?

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

While the active ingredient in TERRO® Outdoor Liquid Ant Baits will ultimately kill the worker ant, it 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 bait 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.

    Amazon Review By J. McHugh

    Tried this on a neighbors recommendation. Had a big carpenter nest in our backyard, and we're seeing quite a few ants in the house. Within a week or so, it seems the nest was largely beat! We stopped seeing ants in the house. I placed all 6 baits outside around the perimeter of our home, and seems they did the trick.

    Amazon Review By Erin S.

    I feel stupid saying this, but I had a hard time with these baits. I was using them outside, and getting them turned properly and crushed down so the liquid was accessible to the ants was hard for me. The baits were also bigger than the other baits that I've used, which meant they were much more obvious in the yard. I've loved other Terro products, but this isn't one that I think I'll be using again.

    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.
