With TERRO outdoor liquid Ant bait stakes, stop the problem at the source. The stakes target ants outdoors before they can make their way inside. The slow killing poison gives ants time to transport the bait to the colony & the queen, eliminating the ants you see, & the ones you don’t. The baits are easy to use - simply place the stakes in outdoor areas where ants have been observed, break the tab open, & let the bait work its magic. A see through bait monitor helps you keep track of when it’s time to replace. The stakes are weatherproof, offering protection through all elements.

As others mentioned, there can be satellite colonies that end up bigger when you attack the main colony. What I did (and worked for me) was putting these out for a month, then getting more and searching out the newly forming colonies and relocating the bait.
I then bought every product Terro sold, the liquid drops put in beer caps in trees, put drops in the crooks of the trees, took some of my indoor terro traps and attached them to the trees with twist ties, etc...I even bought green plastic bait traps stakes, filled half with granules, half with liquid bait...
But by far, the best was when I tied the Outdoor staked Terro Traps in the crook of the trees...(see Photo). Finally, the TRFant showed interest and I am hopeful that it will help to wipe them out. Suggestion: Use a sharp pruner or scissors to cut the tab off the end of the bait. Instructions says to snap tab off, but most would break off at the ends, not enough to open the bait up. More success by cutting it either before or after placement.
Thank you Terro! Will be ordering more.
At first I thought the spike & container looked cheap but the ants found it and then they disappeared.
Until a few weeks later ... I put out a second fresh trap and the ants could not have cared less. They even ignored the drop that I put on their path ... they check it out and walked around it. I've read that ants change their needs during the year ... and right now they aren't taking the bait.
Terro also makes indoor ant killer bait: TERRO T300 Liquid Ant Baits - 6 Pack I have the same refill advice
How it works: The active ingredients are sucrose (sugar) and sodium borate. The mechanism of how precisely sodium borate (also known as sodium tetraborate, disodium tetraborate) kills insects is not completely understood but current theories suggest that boron ions bind to and interfere with key cellular molecules essential for forming the insect's exoskeleton and and carrying out cellular respiration, the process of making energy molecules from sugar. The sugar and sodium borate are dissolved in water forming a thick syrup. This syrup is key because adult ants can only ingest liquids. They bring this food back to the colony where they regurgitate what they ate outside to share with the larvae and non-venturing adult colony workers, and ultimately the queen. Eventually, the sodium borate goes to work killing the entire colony. The process is slow which makes the poison effective - there is widespread colony consumption before the food harvesting adults die. The replacements go back to the bat trap (following a scent laid by the prior scouts) to repeat the process. Eventually the colony crashes due to lack of adults to gather food and tend to larvae. One of the principal advantages of using sodium borate is that it's highly toxic to insects but has very low toxicity to mammals (humans, dogs, cats, etc.), birds, fish, and reptiles.
Kudos: Frustration free packaging; clear, concise instructions; non cancer forming; low toxicity to mammals (humans, pets, wildlife), birds, and fish, but lethal to ants, especially the omnipresent Argentine ant; its design limits killing unintended insects (beneficial insects such as spiders, ladybugs, mantis, etc.)
Quibbles: Care must be placed to avoid crawling infants, toddlers, or pets. The sweet taste of the poison makes this trap interesting to the unknowing child or pet. Also, I found it a bit of a challenge to cut off the clear plastic cover using household scissors without spilling the contents. (Be warned, sodium borate stains light-colored grout ...) I found it easier to open up the green sleeve, pull out the clear container, cleanly snip off the cap, and then place the clear container back into the stake and closing the green flap.
Verdict. It takes about 2-3 weeks to see results.
Tip: Avoid direct hits by sprinklers. Really hot weather will dry up the poison prematurely. You can extend the life of the bait trap by adding a drop or two of distilled water into the trap to re-hydrate the mixture. Remember, adult ants can only consume liquids so dry poison will not work!
We saw an increase of ant activity in the house for the first few days after I put out the stakes, and then, POOF. Gone. No more ants!
At one time, I wanted to order more of these, but Amazon was out of stock. I ordered another brand, and my mom soon saw ants wandering throughout her house, floating in the cats' water bowls, and coming up her sink drains. Yuck. I bought these stakes as soon as they were back in stock, put them around the house, and within a couple of days, again, no more ants. These things work.
I can't remember what the directions on the box say, but I replace the stakes every three months. If I go longer than that, Mom will start to see a little ant here or there, so I stick to a three month schedule.
These stakes have been an easy and convenient answer to the house-ant problem that plagued my mom for years! I can't speak to their effectiveness for other types of ants, but for the indefatigable, year-round, nuisance house-ants of the Pacific Northwest, these stakes can't be beat!
After trying almost every product on the market I tried making my own with borax, wet cat food, and plastic bottles that are too narrow for other animals to get into. That worked, but way too slowly, and the nests were not completely dying out because the colonies were so large that they were getting nourishment from other food sources at the same time.
I finally figured out that the only way to get rid of the particular type of "grease" ant that plagues my property is to buy the kind of ant/roach spray that comes with a long skinny straw that you can stick into the microscopic holes that lead to their nest. If you put wet cat food out for a bunch of hours you will soon see a trail of ants that will lead you directly back to their nest. Mine mostly nest in my window sills, door frames, and crevices in boards under the deck. Find the nests, stick that straw in, spray for about 30 seconds, and thousands of ants will start falling out of cracks and crevices you didn't even know were there. It is a horror show that will leave you with nightmares, but at least you won't be throwing money away on baits that really only work well on "sugar" ants.
These lasted all spring and summer and until I prepped my home for winter. I was truly amazed how great of a product it was. A+++++++++ I love this product!
By the way, I pushed these stakes way down into the area around my patio and didn't have to touch them again until I removed them before winter.
After a few weeks I added another couple of bait stakes near the first in case the liquid bait was running out. The instructions say to leave the bait in place and to look at the level of the clear liquid through a small transparent piece of plastic, but I find this very hard to do due to the design of the product.
My only other minor complaint is that you need to break a small plastic tab off to open a hole to the bait just before you place it. The instructions say to just break it off, but the plastic is actually quite flexible, so it takes about a minute of bending the tab backwards and forwards to weaken it enough to remove.
However, these are very minor points and overall I am pleasantly surprised at the product's effectiveness. As I have purchased competing products I will give them go, but I'll definitely buy these again in future as they are so effective.
