Grabbed These for Carpenter Ants, So Far So Good, Fingers Crossed, but Haven't Seen Any!
I’ve been using these ant baits for about a week and a half now, and they seem to be working really well so far. We had a persistent issue with carpenter ants that we just couldn’t get rid of, and even though these traps didn’t specifically list them, I figured it was worth a try, and I’m glad I did! They’re very easy to set up, just twist off the small tab on the end and place them in areas where you’ve seen activity. Since the bait is liquid, it’s best to set them on a level surface so it doesn’t spill, but the trays have a small lip that helps prevent overflow. After placing six of them around the house, we noticed a significant drop in ant activity within just a few days, and (knock on wood) haven’t seen any new ones since. The traps last for a bit as well so they're easy to just set and forget, and the design helps keep any sticky messes or liquids from being sprayed around, which also makes it a little safer for your pets and kids. The value is great too, you get three packs, so there’s plenty for future use if needed. All in all, these have been an easy, low-effort, and effective solution so far, that I’d definitely recommend!

Dealt with little black ants quick
I had little black ants in my bathroom and thankfully in my situation I was able to figure out where they were coming from outside. So I placed two of the baits near their trail. Within 24 hours they were out of there. I saw them getting into the bait as soon as an hour in. These were highly effective for me and kills ants by taking the bait back to the nest! Just make sure you keep your dogs and children away from them, but overall since the bait just stays in the plastic, they’re fairly safe. I think the price was pretty good. I was able to use just two for the invasion in my bathroom and used a couple more baits when I saw trails heading toward my house. It’s worked well and fast each time so far! Just remember that not all ants like the same bait so there could be a chance the type of ants you’re dealing with may not like it.

Works well with no mess. Killed the ants overnight every time so far!
These ant traps have been lifesavers. We've tried different pellets and sprays to keep ants at bay with mixed results. The first time we used these little Terro bait traps we found it was super easy to use. Once we trimmed the corner and placed in the high traffic area we started seeing ants grab some of the goo inside and take it back to their nest within 10 minutes. After leaving it overnight we found a handful of dead ants and the trap still had half the poison, which surprised us with how long it can last. We've used these three times now, and our extended family has used them, and ants are gone within a day every time so far. Main disclaimer is that we've only tried them with small ants, not sure how well they'll work with fire ants or larger ants, but I'll give these the first shot when we deal with them. Great bang for the buck and saves a ton of time compared to the old sprays. 10/10

Effective ant control that works at the source
I have used these ant bait stations and found them to be very effective. The ants are attracted to the bait and carry it back to the nest, which helps address the problem at the source rather than just temporarily reducing activity. It takes a little patience, but after a short period the ant presence noticeably decreased. Easy to use and reliable if you are dealing with a persistent ant issue.

Effective, But Requires Patience Through the First Few Days
These TERRO Ant Killer Bait Stations do work—I placed them in some corners of my home as recommended. The most challenging part is the first few days: you have to be prepared to see increased ant activity as the bait attracts them. They come out in noticeable numbers, and it can feel a bit overwhelming seeing them crawling around. However, that’s actually a sign the bait is working. The ants carry the liquid back to the colony, and gradually—I’d say within about two weeks—their numbers decreased significantly. By the end of that period, the ants were gone. If you can tolerate the initial phase, these stations are an effective and easy-to-use solution for indoor ant problems. Just set them in ant-prone areas and let them do their job.

The War of Ants Is Now Finished
We randomly started getting ants for the first time after years of living in our apartment. We tried a couple of things to try to get rid of them but this by far was the best solution. Within a matter of a couple days to a week the buggers were completely gone! They are individual tablets in which you twist and tear or use scissors to create a whole that the ants crawl into to and either get stuck or bring back the poison to the ant hill. This worked great because we couldn’t find the origin of where they were coming from. You get three boxes each with 6 tablets. That definitely more than we needed because one tablet worked great. So I guess we will be passing them one to our future posterity as a family heirloom. Haha they are nice and small which allowed us to put it between a tight space where we saw the most of them come from. Definitely recommend!!

I had ants every where! Now they are all gone! Highly recommend!
I had ants in the house all last winter and I was going crazy when I find even more in the spring! The ant control I had tried before had no effect! It didn't take long for the ant baits to be full of ants! It was amazing to see how well it worked! All the ants are gone! The design could have been better. Once you cut off the top the liquid is close to the opening. I put the baits behind shelves etc so none bumped into them by mistake. My daughter's dog ignored the baits but they might not be safe for a puppy who likes to chew on things! The liquid is really sticky! I got some on my floor but I was able to clean it up. It would have been a lot more difficult to remove from a carpet! This is the best product to get rid off ants! I can't believe that they are all gone, both inside and out!

Great product for killing ants
If you have an ant problem, this is the product for you. I had 4 different spots around my house that had ants and I placed the product for one day and noticed the next day that a lot of ant had crawl into the liquid and die. Also, the trail of ants were not longer there on all four spot. I highly recommend this product if you have an ant issue.
