T1813B Outdoor Ready-to-Use Liquid Ant Bait Stake Killer Trap - Kills Common Household Ants 12 Stakes

These were so easy and efficient and worked well! They kept up for over a month and filled up with ants before the liquid ran out. Worked really fast. I used these in my milkweed garden to get rid of ants that were everywhere. They were very durable and kept up through the weather and lawn maintenance.

I have ants on my 3rd floor’s balcony. I placed about 5 traps in less than 10 minutes, within 20 minutes I had large congregations of 30+ ants per trap, were there used to be only 2-3 ants before. These traps are highly effective attracting the ants to the sugary poison. Tip: I followed the advise of some of the reviews and spill the poison at the mount of the trap (as the trap entrance might get a couple of millimeters off the surface). I don’t know yet if the poison is effective, I will update the review in 1-2 weeks on this. Edit after 10 days of use: The traps killed a lot of ants the first couple of days, unfortunately, I have too many colonies of the large ants everywhere, so it took some effort and perseverance to get rid of them. In my experience, positioning the traps vertically is mostly ineffective, as it is very difficult to have the trap mouth make contact with the wall, those few millimeters off the wall make a big difference, very few ants find their way into the trap. However, if you placed the traps horizontally (on their bellies) and squeeze them a bit to spread 4-6 drops of the poisonous syrup next to the trap mouth, ants will instantly find the sugary poison and start collecting in large numbers around the venomous drops, thus the traps are good, but need to be placed correctly. Even with these strategies, I still have ants after 7-10 days, remember the larger ants are a bit more stubborn than the little ones (and resistant). I live in Florida and ant colonies can get really big here. After 5 days I came home and saw large ant balls on the garage walls, I was able to see them from 10-15 feet, when I came closer, I realized that the Queens had abandoned the nest and were surrounded by other ants (queens were big and have wings) these phenomenon happened almost every day for 4-5 consecutive days, I took advantage of this opportunity and sprayed the queens with Clorox, killing so far no less than 20 queens in 5 days - a testament of how large these nest can get here in Florida. In summary, this product has created a havoc inside the ant colonies, killing a significant number of them every day, including bringing the queens out. Some nest had completely disappeared, while others are about 70-80% gone. Changing the traps after storms, or spreading drops of poison has proveen to be effective. I have killed thousand of ants so far and managed to reduce my (outdoor) ant problem by about 80-90% in ten days. I still give these traps a 5 start rating as the destruction they create on those colonies is impressive. Unfortunately, the amount of colonies and ants I have outdoors is just too ginormous, so for these traps - as good as they are - they need multiple days (or weeks) to completely disseminate all the nests.

The TERRO liquid ant baits for outdoor use do an okay job overall, but they don’t feel quite as effective as they could be. They work, just not as aggressively or consistently as you might expect if you’ve used TERRO products indoors or had really stubborn ant activity outside. On the positive side, the stakes are convenient and easy to use. You simply place them in the ground near ant trails, entry points, or areas where ants are active, and you’re done. There’s no mixing, no mess, and no guesswork. The design keeps the bait protected from rain and pets, which is important for outdoor placement. Having 12 stakes in the package also gives you flexibility to cover multiple problem areas around the yard, patio, or foundation. The liquid bait does attract ants, but not always as quickly or aggressively as hoped. In some spots, ants found the bait fairly fast and activity picked up around the stakes. In other areas, it took much longer for ants to show interest, and some stakes seemed to be mostly ignored. When ants do feed on it consistently, you do see a reduction over time, but it’s more gradual than dramatic. Effectiveness feels a bit hit or miss depending on the ant type and location. It helps reduce visible activity, but it doesn’t always feel like it fully wipes out the colony. In my experience, you may need to reposition stakes, use additional treatments, or be patient longer than expected to see meaningful results. It’s helpful as part of an overall ant control strategy, but it may not be strong enough on its own for heavier infestations. Build and formulation quality are fine. The stakes hold up well outdoors, don’t leak, and are easy to remove or relocate. They also last a reasonable amount of time before needing replacement, which is good for ongoing control rather than a one-time fix. Overall, these TERRO outdoor ant baits are useful and do provide some level of control, but they aren’t a miracle solution. They work best for light to moderate ant problems and when ants actively take the bait. With stronger attraction or faster colony impact, they could easily be a five-star product. As they are now, four stars feels fair.

it takes a while but eventually kills the ants. i love to watch the ants get inside and then scurry back to the colony. a few days will go buy and i smile when i see so many of those pesky ants belly up inside the bait trap. i used to spray them but now i just remove whatever food article they found and replace it with a trap. be patient and watch them die! it was hard not to kill them with spray but let them march in and out and you will see the trail get smaller and smaller over time. soon they will depart for good. i put these traps inside cabinets, under furniture, or anywhere i see the little pests start to explore and search for food. aside from burning my house to the ground i find this a great alternative to ridding my life of ants.

I live in NC and we have fire ants- and they have decided that my bushes are great places to build ant hills. I put these out as soon as I notice a mound and it really helps get rid of them! Of course, the relocate a lot of times, but that's not this product's fault.
