TERRO Liquid Ant Baits
Ants can be a problem anywhere – in the home, at work and everywhere in between. To kill common household ants, place TERRO Liquid Ant Baits in areas where you’ve seen ant activity. This will attract foraging ants so they can take the bait back to the nest. As the bait circulates through the colony, it kills the ants you see and the ones you don’t. Within a few days, you should see a significant decrease in the number of ants visiting the bait. The compact size of the bait stations makes them perfect for placement along baseboards, in corners, on counters, under and behind appliances, and on windowsills. The more bait placements you use, the better!
How Liquid Ant Bait Works
Since this is a bait, initially you will see more ants – but don’t worry, this is a good thing. Why? As ants forage for food, they are quickly attracted to the sweet, sugary liquid inside the bait stations. After finding the bait, worker ants consume it and leave behind a pheromone trail leading back to the colony. This trail lets other worker ants know where the newly discovered food supply is. This is why you will see more ants in the beginning.
Meanwhile, the active ingredient, Borax, is slowly interfering with the ant’s digestive system, ultimately eliminating it, but leaving enough time for the ant to go back and share the dose with the rest of the colony. This slow kill is necessary so that foraging ants can make several trips to the bait. The communal nature of an ant colony allows the bait to be spread to hundreds, if not thousands, of individual ants.
How to Use Liquid Ant Baits
TERRO Liquid Ant Baits are very easy to use. Before placing the bait stations, be sure to remove other sources of food, such as crumbs, sugar and grease spots to prevent attracting ants elsewhere. Do not place bait where you’ve already sprayed insecticides, as the pests may avoid the bait stations.
- Hold the bait station firmly with bait pack tab facing up. Break off the tab being careful not to spill the bait.
- Place the bait station label side up on a flat surface near signs of ants. Place additional bait stations anywhere they may enter your home. For best results, use all bait stations to ensure a sufficient supply for the ants.
- Monitor placements regularly, but do not interfere with the pests or bait stations. Replace when bait is depleted. Complete control may take up to 2-4 weeks.
- Once ants are controlled, replace the baits every 3 months to keep them from returning.

I had an occasional ant or two showing up in my office and could not track down where they were coming from. Every few minutes i’d feel one crawling up my leg, I’d pick it off me, look everywhere on the floor and find no others. It’s like they were coming right up through the floor or something but they never revealed their entryway to me.Got some tarro liquid gel bait, placed against a wall under my desk, and the next day I had a line of ants coming from somewhere across the room, all the way over to that bait. Suckers! I moved the bait to their entryway and they’ve been all over it for about 5 days now.I also placed bait in my bathroom where there were some ants. Put it near where they were scavenging but these ants must not be part of the same group because they ignored it for 2 days until I put it right up in their faces, then they swarmed it. These ones liked to swim in it though and clogged up the entrance to the bait. Had to scrape out the dead body clump there to make it a little more attractive to future ants who may not like the idea of climbing over a pile of their dead family to get to the food.Looking at the bait over these past few days, it seems many ants just get stuck in the gel and ultimately die. I’m not sure how much of this is actually making it back to the nest. Activity around the bathroom bait is definitely slowing though. Lots of ants hanging around but don’t seem to be doing much, almost like they’re drunk. They brought in reinforcements too, some at least 2-3 times bigger than what I usually saw there, but they too are stumbling around like drunkards now. The office ants are still pretty active though…they too seem to just get stuck and die but have greater numbers.Overall, the bait is working! Watching it work is nearly as good as watching a Netflix series.UPDATE: It’s been about 11 days or so and the office ants don’t seem to be slowing down. I put 3 baits there initially, and they slowly filled up with dead ants (1 was even completely dry) so, I decided to replace those with 3 fresh baits.The other 2 ant locations I used this bait on worked really well and only took a few days to see a slowdown and eventual end to their activity there, but these office ants are apparently sturdier and have greater numbers.Hopefully these 3 fresh baits are enough to finish off the office ants. Again, not sure on how much of this gets back to the nest… They all just seem to get stuck and die inside the bait. Will report back on progress.UPDATE 2: Been just over 2 weeks now and the office ants are finally slowing down. I’m gonna conclude this room took longer simply because there were a lot more of them there than the other rooms. Eventually, they’ll all die but you gotta be persistent and replace the baits when they inevitably turn into graveyards full of bodies. Probably another week and this group will be done for good.

So far so good. Easy to use, just cut the tip off. Place it down and a few hours later the ants are swarming it. The next day they are gone. I get t hose little crazy ants, that don’t go in a line but scout all over the place and you can never tell where they re coming from! so frustrating. I drop one of these down and leave it. A hour later there is a black mass there. I’d say place it on a piece of paper or cardboard or something, because it gives me a tiny stain on my carpet when they leave with t he bait, but otherwise not bad? And honestly, by the next day not a ant is seen. They seem to last a while too, which is nice. And t his pack had a lot in it, so when ants show up much later, I put a fresh one down and don’t worry.I have two cats, and so far they are not attracted to these nor do they bother them. I tend to put one down by a wall and prop a tall book or binder or something in front, or even cardboard, against t he wall, so it’s like a hidden tent. But even then they don’t seem t o care, and it’s been safe so far!When i get down to my last one, i WILL be ordering another box to keep on hand. One has been enough to take care of a problem for some time. So one box lasts a while. A++ Still buy again.
While these are amazing, there are some inherent issues.1. It takes time for the ants to collect the goods and head back to poison the colony. You will have a massive string of ants that you’ll just need to deal with. It takes a few days.2. If you don’t pick these up after ants are gone, you will have another set of ants that come to find the poison and you’ll need to repeat step 1.3. There is still poison left and there’s no way to package up or save for later. You’ll need to find another spot to deploy until the liquid is gone.4. It’s liquid. It can leak. Hold it properly and carefully.5. It’s not a permanent solution. It’s to fix problem areas and is not a preventative.As far as pros go,1. The dogs and cat don’t seem to be interested.2. You can see the results with the massive graveyard inside the liquid.3. 12 come in a box – and you wont need that many at first (unless you have multiple problem areas (I did).Overall I would buy again, but it’s not a solution in itself to prevent ants from coming back.

I very rarely write reviews which is kind of stupid because I usually read reviews prior to getting certain products. Therefore I guess I will start now, hoping I can help someone decide wether or not this product is for them. Before you read this long review I want to let you know this is the BEST product I have ever used.Before I tell you about how AMAZING this product was I will tell you what kind of Ant ? problem I had. Maybe someone can relate.I have a parrot and he is in a room that is near a window. With all the different types of food he eats and with the warmer weather that we started having in my area (NJ) I started seeing ants outside. That’s when I started seeing some ants coming in from the bottom left corner of the frame of our window. I have never had an ant issue with the 17 years I live hear. Even having my parrot and all the amounts of food he eats. For some reason last year during the spring time is when I saw these crazy little annoying bugs come in my house.These ants seemed to be a different type of ant. One I have never seen before. They were small but the minute you go near them they would run away or scatter away super fast. I have an exterminator on my block and he told us they were sugar ants. What the hell is a sugar ant? Lol. Well I was told that these ants hide out in your shower and in the kitchen because of the sugary foods around. Why are they found in a bathroom is beyond me. But I looked it up after what he said and everything he told us was what I read on line about “sugar ants”. I mentioned that last year I had this problem and they were found behind the faucet in our shower. That’s another story. Anyway, before having an exterminator come into my house, I figured I would try to resolve the problem myself. So before buying this “AMAZING PRODUCT”, I purchased all the “Raid” products that come in the square plastic containers. The ones that come in white or grey containers. I put the Raid traps by the window and where else I thought they might come in. I actually tried the mixture of vinegar, sugar and water concoction that was told on line to use for these ants. But nothing worked. I doubt an ant even went to these traps because near my window they would go around those traps. I was getting frustrated because I skeeve bugs. And I was afraid of an exterminator coming in with my parrot living here. I wasn’t taken that chance of him dying with the chemicals. Anyway after coming to a dead end with the Raid traps I began reading and reading on so many products just to find a worthy product. That’s when I came across this product. It was very different than the normal products that are used to kill ants. So I figured why not, let me give it a try. I received my order really fast and was anxious to use them. After reading all the directions these baits were very easy to use. It comes in a thick clear rectangular container. To open it, it Reccomended to hold it up right and twist off the plastic top until it snaps off. It was a little tough for me to snap off the top like it says on the package. Therefore I used a pair of scissors to open the trap. Word of advise, if you need a pair of scissors to open your product, just make sure to keep the trap upright so the liquid doesn’t pour out. After opening the trap, I then placed this trap about 3-4 inches away from the bottom corner of the window. Right where I saw the ants coming in. They scurried away from me at first, but the minute I put this trap down it was shocking!! No joke. I was shocked to see all these ants go running toward the opening of this trap. The trap actually attracted more ants to come out of hiding to eat this food (crazy). I actually spilt a little bit on my windowsill and some ran to that and got stuck. But what was amazing to me was after I put the trap down and watching these ants go to it, it was shocking to see them run right back out of the corner of the windowsill. It was crazy. I just watched for a few minutes and to see them either get trapped inside the trap or grab some of the food in the trap and run back outside or wherever they came from. And by the end of the day they were gone. It’s about 2 weeks now since I only used one trap and I have yet to see another NASTY ANT!! Wahooo!!!! They are gone.This product is BY FAR THE BEST ANT PRODUCT I HAVE EVER USED IN MY LIFE!! This is noooo joke. Therefore you can count on me to continue to purchase and use this product for any ant problem that might arise again. I will never buy a different type of ant trap again. No matter how popular people feel the “Raid” products might be. The sprays are only wonderful for the outdoors but for the inside the “Raid” products are definitely not as effective as this product is. I actually gave my neighbor 2 traps and after a day or two they were gone by him as well. These traps are crazy how wonderful they work. I swear by this product and I know if you purchase these traps you will too. I will never buy another kind of ant traps again. These are the BEST kind of ant traps on the market by far!!! And mind you, I AM NOT making any kind of commission from this company for this product review. I am just sooo happy my ant issue is gone for now. Sooo, if you want to get rid of these annoying, nasty bugs “FAST,” then purchase these traps. And I promise you, you will be so happy you did.
we just moved in to our new house less than a month ago and almost immediately we had ants coming in to all rooms as if our house was going to bust at the seams. even places with no food. and we keep everything in our pantry pretttyyy sealed up and make sure we clean up messes and run the vacuum daily. AND we used our pest control spray that we usually use. and did all the other tips with vinegar etc etc.BUT THEY STILL CAME IN RELENTLESSLY EVERYWHERE. This picture is from our master bedroom CLOSET, and we placed them in 5 other places -basically each room in the house where we knew there where secret entry portals somewhere. I spent the whole day finding all their secret portals while waiting for these to be shipped.after reading like every review I knew to cut off with scissors and that they’d be kind of messy and spill out so I used paper towel /cardboard. and actually spilling it out helped since the design doesn’t really make sense.after several hours they were almost gone and by morning, zilch. now it’s afternoon and still none!we had made an appt for pest control to come Monday but honestly if we don’t see anymore this weekend we might cancel and see how it goes.PS- it’s a GOOD thing if they all start coming in droves, that mean you found the secret portal and they’re gonna take it all back to their colonies. it’ll get worse before it gets better. I’m surprised ours went away so fast with how many we’ve had over this past month we lived here.
I USE TO SPRAY PEPPERMINT ESSENTIAL OIL MIXED WITH COCONUT CARRIER ON THE ANTS. IT DOES WORK WELL BUT THE ANTS DIE RIGHT THERE ON THE SPOT SO YOU’RE NOT REACHING THE COLONY. MY HUSBAND WENT TO HARDWARE STORE AND BOUGHT D-CON ANT KILLER. THAT WAS A JOKE, I THINK THE ANTS EVEN LAUGHED! FINALLY, I PITCHED THEM! I READ THE REVIEWS FOR THIS PRODUCT AND THOUGHT, OKAY, I’M GAME. OMGOSH, ALL THESE ANTS CAME FROM EVERYWHERE ON MY KITCHEN COUNTER. I WANTED TO KILL THEM BUT KNEW I HAD TO WAIT FOR THEM TO RETURN AND DESTROY THEIR COLONY. IT WORKED!!!! I’VE BEEN ANT FREE ALL SUMMER! I TOOK 4 DOWN TO CAMP SINCE WE’VE BEEN BATTLING ANTS THERE. I PLACED ONE ON THE COUNTER AND WHEN WE RETURNED BACK TO CAMP AFTER 3 WEEKS THERE WERE QUITE A FEW ANTS DEAD AROUND THE PRODUCT AND THERE’S BEEN NO ANTS SINCE. I WOULD HIGHLY RECOMMEND THIS PRODUCT BUT REMEMBER ALLOW THEM TO GET BACK TO THEIR NEST

Ok, haven’t written a review in a while as I’m usually very descriptive and detailed but will try to keep this one simple. I can’t be 100% sure that it was this product that did it alone as we triple attacked. Allow me to explain.We had a big birthday party for our kids and it took a while until family who stayed with us along with their kids eventually left. Bottom line the house wasn’t exactly immaculate but any standards. The little tiny black ants showed up out of nowhere and had a steady stream in and out of the house by way of what appears to be a space in the deck door jam that leads into our kitchen. They went along the base molding up the cabinets and asking the granite counter at the edge of the wall in the kitchen all the way across and over to the other side of our stove where we keep a small garbage can for our compost items. But they weren’t drawn just to that I’m sure.Anyhow, I’ve crushed them, wiped them away, and sprayed vinegar. The later worked for maybe a day or so each time we tried.Enough was enough so I bought this and Amdro Ant Block Home Perimeter Ant Bait, 1LB 8oz (24 Oz). Put that outside and swept it under the base of the vinyl siding and doorway around where the ants were coming in. Inside I see these traps up. Only reason for giving it one star less on of the features is that the tabs don’t easily come off and literally without my forearms every morning. Note to their QC/CS peeps, these should be perforated to make it easier for customers or tell them to cut them off.Anyhow, I wasn’t playing song and laid out three along the counter and two in the floor from the doorway to the counter.Bam – the triple play combo worked in a single day. I haven’t removed the traps over the past three or four days done I set them just to be sure. Love the immediate results.Will see what happens after I remove them… as in will they come back.
I don’t write a lot of reviews but I felt compelled to follow up on this product. I’d been fighting this little sugar ants for a month. Tried all the natural products first, cinnamon, peppermint, other non chemical sprays. They’d work for a day or two and then they’d be back. Tried borax and diatomaceous earth, they worked a little better but they still returned. Got this product, put one down at the base of kitchen cabinets where the dog couldn’t get to it. Within a couple hours, noticed a steady flow of hundreds of tiny ants getting the bait and back inside the wall. About three hours later, they were gone!! Never to return. It’s been a month, no more issue. Repeated the same process in my den and again a few hours later, ants were gone and haven’t returned. I followed a tip from another reviewer – I put a small piece of foil down with painters tape holding the edge down, tipped the bait slightly to put a drop out on the foil. Boy did they flock to that. Anyway, the foil/tape made cleanup easy as the bait is sticky.
I had to do 2 rounds of this (Borax goop) treatment on my kitchen counter. I thought they were gone but it took 2 weeks of invasion and patience to wait it out. So much stressing, but finally no ants. I took up 1 of the 2 packets. left on a 3 day trip and came back to ants everywhere ..ignoring the packet I had left. There was still liquid in it so I pour a drop out to lure the ants, put out a new fresh one and let it sit another 2 weeks. Again an invasion… waited 2 more weeks but see no more ant. So that took a full month and I am leaving one of these on my countertop for any that may come looking. (These were tiny ants) FYI.. do not bother to twist off the top to open a packet. I’d already read how hard it was to do that, so just have a scissor ready and drop 1drop and lay the packet there, no ants ever went inside for long. You need to pour some so they definitely partake and take it back to the whole bed that will die. They circle thick around the poured out dot of goop. This stuff is majorly tacky and it cleans up easily with hot water.

So, I just moved into my apartment about a month ago. Living in Wyoming and all of its temperature fluxes recently I started noticing these little buggers coming out OF MY CARPET. Now, I have a fear of ants and small bugs alike, so as soon as I saw a small cluster of them, I immediately took to amazon to find something that works. In the first two pictures I uploaded, that was after roughly 4 hours after I laid two traps down. Obviously extremely shocked at the sheer amount I had just discovered compared to the small cluster I saw the morning before, I grabbed a couple more traps and readied my defenses. I now had three traps ready to battle these little shits. In the second two pictures you’ll see just what happened with having three down. EVEN MORE KEPT COMING. Those pictures were taken roughly an hour after I set the third one down, so now, roughly 5-6 hours after first setting these ants up for failure, I had lured out HUNDREDS and boy were they hungry. Upon my moms advice i did decided to vacuum up some of the stragglers so i didn’t have to keep looking at all of them crawling around (also, I thought those in the traps were dead). Right when I started that, BOOM, they all started fleeing from my vacuum suction. The ants in the traps were ALIVE. So , obviously freaked out by this even more and after vacuuming up probably 200 ants, I left some stragglers so they had the chance to go back and poison their queen. I then laid two more traps and essentially created an arch of traps to keep them consolidated to one place (they are on the edge of my kitchen and i don’t want them spreading). So now, 5 traps down and 7 hours later, the ants still can not resist the delicious goodness Terro puts in these traps. Now, I have only spent a single day with these and seemingly only lured them out to feed, BUT i am hopeful these will begin working and I will leave the 5 traps overnight and view the situation in the morning – HOPEFULLY I will have successfully infiltrated the queen and killed her along with the colony. Obviously the company recommends a couple weeks to see results, but based on what I see now along with others reviews, I don’t think they stand a chance. I will update in a few days with the ant infiltration among my carpet and I hope it’s a good situation by then.UPDATE:So here we are, about 24 hours later and oh. my. god. these traps work. When I came and looked this morning there are far less ants than yesterday! In the last two photos I added, you’ll see just how many ants there are now and boy is it less than before. Now, I’m unsure if the lesser number means that I’ve successfully infiltrated the colony and killed them off, or if their tummies are just full from eating so much – either way, I don’t see nearly as many today. The ones still present are certainly moving slower than before, my guess is these Terro traps are penetrating their stomach and killing them off (this is what I hope). Overall, with this intense decrease in ants after only about 24 hours, I am impressed and will certainly be ordering more as Spring rolls through and I’m sure they’ll be back if I haven’t killed them all. I will update once more in a few days as well just to give my final thoughts but so far, I’m sticking with the 5/5 stars! I also have someone coming to spray in a few days, but if these are working I may just send them away!
