Works!
🧪 My personal experience I used Terro Liquid Ant Killer when ants started showing up in my kitchen, and it honestly worked better than I expected. I placed a couple of the bait stations where I saw the trails, and within minutes the ants were swarming them. I was kind of grossed out at first, but within 2–3 days, the traffic slowed down—and by the end of the week, they were completely gone. ⸻ ✅ What I liked • Strong cleaning power: The borax formula attracts ants quickly and works by having them carry it back to the colony, which helps get rid of the whole problem, not just the ants you can see. • Fast results: It worked within a few days for my situation, and I didn’t need to constantly reapply. • Easy to set up: The pre-filled bait trays are super convenient—just snip the top and place them where ants travel. • No strong scent: It’s odorless and not irritating, which I appreciated since I used it indoors. ⸻ ⚠️ What to watch for • Leaks: The liquid can sometimes seep out and create sticky spots, so it’s best to place it on foil or a paper towel to protect surfaces. • Takes patience: You do need to let the ants gather around and take it back to their nest—it looks worse before it gets better. • Not ideal for huge infestations: I think it’s perfect for light to moderate ant issues, but larger infestations might need additional help. ⸻ 💸 Value & sustainability It’s super affordable and lasts a while. I also liked that it’s considered a less harsh chemical option compared to sprays, which makes it feel a bit safer to use around the home. ⸻ 🧾 Final verdict Terro Liquid Ant Killer is definitely something I’ll keep on hand. It’s easy to use, works effectively, and gives real results without a strong smell or mess—just be prepared to wait a couple of days while it does its thing. Great value and peace of mind in one little tray.

Trust the process! Works!
Terro=the only thing that truly works for ants! Highly recommend, but you’ve got to trust the process as more ants will appear before they all disappear.

WORKS!
I've tried them all and always come back to the old tried and true! Within days, there was not an ant to be found in my kitchen.

Awesome for killing anta
This is not my first time using this product. First use was the clear plastic containers that you just open the end on,which work just as well and are nice but sometimes/ most times I don't want that bulky plastic piece sitting around. I just drop a drop or two in behind base boards or whever my cat can not get into,and with no time all ants are gone!

Messy but works
For $3 it's pretty good deal. It attracts the ants who either get stuck in the goop or take it with them and go die somewhere. Unfortunately it is very very messy and it dries like strong glue–there's a small piece of one of the package cutouts permanently stuck to my floor and I'm going to need to use Goof Off to take it off. It also needs to stay where it is for a long time, it takes a while to work. It is effective though. KEEP AWAY FROM PETS it is toxic and it will stick to their paws fur etc. I'd recommend making a tiny "cup" out of tinfoil (it will spill right off a flat piece of cardboard) and hiding it in a nook where the ants are and pets can't get to it.

Essential for Ant Problems
The key to this bait is the active ingredient (Borax) mixed with sweet bait. The ants are instantly attracted to the liquid. Initially, it looks like the invasion is worsening as dozens of ants swarm the bait stations, but this is the crucial step: the worker ants consume the liquid and carry it back to the colony, including the queen. Within 24-48 hours of placing the bait, the ant activity slowed dramatically, and within three days, the entire trail was gone. The whole colony was eliminated! For the price of a single pack, this product completely solved a pest problem that had been nagging me for weeks. It’s a targeted, effective, and efficient solution that costs far less than professional extermination services.

Very effective!
It works! One day my wife noticed a trail of tiny ants marching from under the baseboard near our patio door, along the edge of the dining room carpet, in single file, right up the wall in the kitchen into one of the kitchen cabinets. My wife had a couple of bottles of honey in there and they were loving it and moving in. We tried all the traditional home remedies, which all failed, and standing there day and night and playing Whack-a-Mole was out of the question. However, this stuffed worked. Within a day, the numbers were way down. Two days, only a few per hour were coming in. Within a week, only an occasional straggler. After that, only a rare ant here and there was left and they were totally gone from the house by 10 days. The manufacturer tells you to leave the traps out for at least a couple of weeks. They haven't returned so far. She's happy, I'm happy, and the ants aren't around anymore- I guess they're not happy. Just one last note: The stuff is not toxic to most pets, but could make them sick if ingested. It's only borax and honey for the most part. Keep the goo in places where Fido, Kitty, and the kids can't get to it.

It’s Messy, but it works
I got this stuff because it was cheaper than the ones that come in the little clear, plastic containers. And I wish I just spent the additional $4 and got the stuff that comes in the prepackaged little “servings”. It says to tear the little squares right of the cardboard packaging & drop a little bait onto the tiny squares. It’s a mess. It leaks off the square, starts to dry & gets SO sticky. It does work, but unlike the stuff that comes in the little plastic things already, you have to keep reapplying it since it’s dries up so fast. I also tried squeezing some into the empty little plastic containers I got last time and ya…don’t do that either. That was an even bigger mess. Lol It DOES work. It takes a couple of weeks, but it works. I’m only deducting stars due to the mess.

simply marvelous product
I am talking of this product that it works wonderfully ......kindly note if this works so weel then there is a danger angle to it pls keep out of reach of children and pets make sure they do not ingest it . This is a transparent gel. odorless so u will literally need to put it in the path of the ants .......in india it would feel that this is expensive product but for the issue of red ants .......its wonderful .

فعال جدًا لكن يحتاج وقت
كنت أشتكي من النمل ( القارص ) ، رغم إني في شقة في سطح منزل إلا أن النمل القارص منتشر في مكان. أحضرت شركة لرش المبيدات - ٣ مرات خلال ٣ شهور - بدون فائدة . شفت المنتج وقلت بجربه ، وضعته في الأماكن التي يخرج منها داخل الشقة وفي السطح، ونسيته لإني كنت يائس. بعد مدة لاحظت أكثر مكان يتواجد فيه دورة المياة خالية تمامًا من النمل، وبديت أبحث في الأماكن الثانية ولله الحمد اختفى اختفى نهائيًا.
