Only Thing That Works. Easy to Use. Fast. Effective. My Ants LOVE!!!
This stuff is amazing. After years of battling little black ants and retreating in defeat after each encounter, I had enough. I have used every variety of Raid, box store barrier sprays, traps, granule and liquid baits like the useless Terro that no bugs are willing to ingest, Chinese magic chalk, homemade borax, soap, and vinegar remedies... Nothing works. The ants live inside my walls and whenever I find and plug up a hole, they find another harder to reach hole to march out of. Finally after a night's worth of research, I found this product. Professional grade, supposedly what exterminators use. The first trial is on a thick trail of ants in my kitchen that had recently taken over my stove. As directed, I inject a small pea size amount along the trail and immediately the ants take to it, covering the whole thing. I inject more, along the whole path. Same result. I watched as their abdomens become extended and translucent while they drink up the delicious bait. A few couldn't stop drinking and died. But most made it back to their lair. It was hard not to spray them in their tracks, watching them eat and then go home. But the next day beneath the wall next to my water heater in the garage, quite far from the kitchen stove, I found a huge pile of dead little black ants. I had no idea there were so many. It was easily 10 times the amount that I baited in my kitchen. I vacuum them up. For three days after that initial feast, pile after pile of dead ants. I'd vacuum, then come back and there's another pile. I felt like I had finally won my first battle against these little guys and didn't see any ants for a few weeks though I suspected there were other colonies throughout my house. Today, I spotted a small group searching for food. Immediately I put beads of this stuff along their track. I was lucky enough to be able to find their entrance this time, which was quite far away from where I spotted the initial group. I made sure to put plenty of this stuff at their doorstep to make it easy for them to eat, go home, and share with the rest of the colony, just in case the exploratory group doesn't make it back. Within a minute, the bait was covered in ants. Ants pouring out of the grate, scrambling to get a sip. I add more, more ants come out. I'm delighted as I watch them eat and grabbed my phone to take pictures and write this very real review. I'll be waiting with my vacuum tomorrow as I claim my second victory. The tide had finally turned in my favor. In this set, you get 4 syringes full of this stuff. Each syringe is 1.06 oz. (30g). After two applications, I've only used about 1/5 of one syringe. You don't need much use sparingly. The syringes are capped. The cap comes off easily and can be recapped to save for later use. This pack of 4 will last a long time. I just moved into this house two years ago and suspect this had been a problem for a while if there are so many ants colonized in the walls. Hopefully this will help me win more battles and eventually eradicate the colonies living within my walls. But very glad that for the first time in two years, and after just 2 applications, I can leave food out and not have to worry about ants. Tip: After all the ants are done, I let the gel dry. Then I scrape it off, throw it away. I then clean the areas thoroughly. I don't leave the gel out because I have small children and this is after all, poison. Also, I noticed it doesn't attract ants when it's dried up. So put a little bit at a time to feed the ants where you see them. Don't empty a whole syringe someplace and think you can just leave it there as bait for months. Good luck!

Absolute Ant Annhilation
I have to admit. I decided to try this because of the flamethrower review,(if you don't know what I am talking about go back and read it, totally worth the minute or less of your time) he wasn't wrong. I had a horrible sugar/pharaoh/pain in the a.. ant problem. I had been surviving just fine, working from home, taking care of the little ones, I admittedly got a little lax about where I allowed them to enjoy their snacks, and as any parent knows kids are messy....really messy and ants are the epic scavengers of the insect world. So these little buggers found the tasty morsels my sweet toothed spawn left in the nooks and crannies I didn't find. One day there was peace and harmony, the sun shone through the windows...and life was good...the next we were overtaken by a massive army of micro sized immortal specks running across every surface I owned. Nothing and I mean NOTHING I tried would even put a dent in their numbers. Day after day, product after product- squish after squish they came in droves. It got to the point where I almost just handed over the weekly grocery grab to satisfy their insatiable appetite, hoping that if I made such a peace offering they would gladly take the atonement and go away. 30 days, about a box of borax, a pound of sugar and 800 useless ant baits later I turned to the internet and its vast ominous knowledge determined to find something effective that wouldn't also sacrifice myself and my sons in the process. Now my mother, as well meaning as she is, has drank the Terro kool-aid. She swears by the stuff. I never had luck with any of it, but according to her it was the only thing she's ever tried that worked. How I don't know. Especially considering that we share the same roof, do the ants on her side of the house truly gobble that stuff up or has she begun to go blind? Perhaps there is an infestation of advanced ants on the west wing of our establishment where I reside. But one thing I know for sure is this stuff works. Yes, I tried the Terro bait....dare I say my "advanced" ants even laughed at me as they turned up their nose to the gel packs which laid in waiting. I even left them out thinking they needed to ferment to be effective, I waited a week and they remained untouched. Then I came upon the magic of Amazon and the flamethrower review, if I said I didn't read it because I wasn't considering using one I'd be lying to you, but this option was far less cheaper, just as efficient and caused no threat of personal or property damage if you followed the packaging rules. I was hooked. Shipping was speedy. Ease of use? Superb. Why this review is asking me about flavor I can't be sure. But I would give it 5 stars as an ant. I used post it notes as "plates" and placed them out along the ant's favorite spot in the room. As badly as I wanted to wait and see if they came and fell for my trap, I was always told a watched pot never boils so I walked away....but oh man I wasn't prepared for the sight I saw when I came back..... I returned to a thanksgiving FEAST, ants swarming the glob of goo I was ecstatic they actually took it...mid dance I stopped myself....but would it work!? The headline to this review is absolutely true. It was pure euthanization of an entire colony. I set out 2 different "plates" and within 2 days tops there was balance restored within the room. Not an ant in sight, oh there were bodies here and there but no living soul graced the presence of my space, save for myself. It was again quiet and the peace was restored as the sun shone across the floor in the room. It's been a month since that day. And no ant dare set tarsal claw in this room. If you're concerned about the price trust me it's worth it. You get A LOT of product enough that I have even given some away to others in need of such a remedy to their pain. I still have enough to last a lifetime..well mine at least not the ants because once you bust this out they haven't very long...

It Works Better Than You'd Think
I've bought a lot of things on this site. Mostly entertainment, some utilitarian, but this might be one of the best products I've ever purchased here. You see ants, you place a dab of this stuff in the area, and the next day they are gone. It's almost magic how well this works. I bought this stuff 4 years ago, I still have a lot of it left (you don't need to use a lot), and it still works perfectly. If you have ant problems, whether seasonal or whatnot, buy this. The ants will disappear.

Works on FIRE ANTS, too!!!
We live in Florida, and have been plagued with indoor pharaoh ants. You don't see those things, but they bite, and it hurts. Looking closely (before I had my cataract surgeries a few weeks ago), I did not see them, but my husband did...allover his bathroom sink, every day! So, I treated the edge of the bathroom sink and vanity, including inside the light switch plates (as I had seen done by a very expensive exterminator, years ago). Our driveway is brick pavers, put in after our sinkhole fix 7 years ago. Through the years, the bricks have separated a little bit. Then, I noticed little piles of sand at some of the cracks...FIRE ANTS! So, I decided to try this on them, too. I put a little squeeze in each of the many sand piles, that were crawling with these really horrible, tiny (again) ants. Yes, one ant found my foot (I go barefoot around the house, outside, too). The pain was horrible!. You don't want to get bitten by ANY fire ant, at ANY time. The pain is going away, slowly, with the help of some OTC remedies. Just went to check on the ant status in the driveway (barefoot, again). Guess what....absolutely NO ANTS, NONE WHATSOEVER!!! HOORAY! Another great use for this stuff. Glad I have 2 more tubes left, to attack more, should they dare to return!!! To add....I did "attack" a couple of fire ant piles in the lawn....they are gone, too! Editing, here....actually, adding more. Those fire ants in my driveway, the ones I treated, are gone. The only thing, they have their underground tunnels, somewhere, maybe even on the lawn, and they are now coming up in a different place. More treatment, needed, but know, it does work. A BIG FYI...DO NOT THROW OUT THE PLUNGER WITH THE EMPTY TUBE, like I did. So, now, I am using a paint brush as a plunger, and did order more, as I have used up 2 tubes, already! This time I WILL SAVE THE PLUNGER! The fire ants I had previously in the driveway have gone from their locale. I do have some more in a different area. They got "theirs", today. On my last review, I said I had mistakenly tossed the plunger. Well, I made a new one, and it works perfectly. I used a short piece of sprinkler extension (the threaded grey pipe), and screwed a cap on it. It works just fine. So, if you toss the one that came with the set, try my sprinkler parts solution. If you don't have the extension but have some small pipe left, cut off a piece long enough to use. Use that with a cap or not. Works fine.

Works very well on vertical areas like posts or window frames.
Works great on ants. Effective within 24 hrs. Sticks very well to vertical areas Took off a star as sometimes, the mound is deep enough that some ants are able to get away and mound moves.

what is happening to my little ant armies that steal all my food?
I decided to order this after walking in my kitchen and getting bit by an ant, it swelled so bad I had to put ice on it. At first I thought it was a spider bite, but then I checked my kitchen floors and yup it was full of ants going after a piece of meat! This year I have tried keeping dishes clean because in La I am trying to limit my traveling due to covid- last year id wake up to a kitchen full and just leave for the day hoping by time I got back theyd be gone or my husband would be home to spray them with surface cleaner, wipe em and wash the dishes. Anyways this stuff came and I basically washed my dishes so they would have nothing but this to eat, I went out to the front where I noticed a line I put some of this bait- within seconds they were all over it! went to another line in my front yard that seemed to be a different group after a different source of food and again they were all over it. went to the back yard to 2 different lines of ants and they were both all over it. The ants were picking it up and taking it away and by the evening they were gone! leaving me wondering where they are. I have dirty weekend dishes piled up high and theyre no where to be found. I did notice a few stranded ones here and there and did leave bait for them but I think its working. I went through one valve- or syringe and still have more left. im so relieved becuase this property has not been treated for ants for 10 years that we have been renting. And I didnt have to put the bait indoors. Its easy to see and can be removed if you have concerns for pets.I had ants that seemed to be meat eaters, but they have came for my cereal this year too! and All of them are gone. now I can go back to my normal habit of not sweeping the floors everyday and not washing dishes every time i use one- even though I must admit it was kind of nice to see the kitchen so clean. ill update if they come back but if see them outdoors I will go give them bait. UPDATE: So its been all summer and I haven't had any ants in the kitchen. I had very few outside on my orange tree and by my trash can but I kept putting bait out everyday or so and theyre gone. I cannot believe its this easy to get rid of ants. I did notice working baby ants in the front yard, I guess times are tough when you have to send the kids to work right? Anyways theyre all gone. Ive been leaving chicken plates on my counter over night. Sometimes all week and no ants. Cookies can be left on the kitchen table and no ants come. Last year and for the previous 10 years its been a battle. I wish I knew of this stuff before but im glad I finally figured it out!

Great purchase!
Worked with one application! we had ghost ants in Florida and put the gel in a few spots outside around windows and inside then on inside of power outlet cavities and haven’t seen ants since. They definitely were attracted to it and a few died immediately but the rest left and haven’t seen any since! Well worth it!

The tide has turned! I march to victory!
This stuff is amazing. After months of little ants giving up after each defeat, I had enough. I have used many variety of ant killing products both inside and outside the house.... Nothing worked. The ants live inside my walls and whenever I find and plug up a hole, they find another harder to reach hole to march out of. Finally after a night's worth of research, I found this product.

It was hard not to spray them in their tracks, watching them eat and then go home. But the next day they disappeared. I could only find a few dead ants along their trail and I haven't seen the main army since! The next day I decided to go on the offensive against the remaining trails of ants inside my home. Immediately I put beads of this stuff along their tracks. I was lucky enough to be able to find their entrance this time, which were both in my bathrooms and along my windows. I made sure to put plenty of this stuff at their doorstep to make it easy for them to eat, go home, and share with the rest of the colony, just in case the exploratory group doesn't make it back. Within a minute, the bait was covered in ants. Ants pouring out of the grate, scrambling to get a sip. I add more, more ants come out.

I just moved into this house one year ago and suspect this had been a problem for a while if there are so many ants colonized around the home. Hopefully this will help me win more battles and eventually eradicate the colonies living outside my home. But very glad that for the first time in a year, and after just 3 applications, I can leave food out and not have to worry about ants. Tip: After all the ants are done, I let the gel dry. Then I scrape it off, throw it away. I then clean the areas thoroughly. I don't leave the gel out because I have small children and this is after all, poison.
