TERRO T300B Liquid Ant Killer, 12 Bait Stations

We had an unusually bad ant problem this summer. Normally, they would go away after a week or so and not come back until the next summer, so killing them really was not necessary and my preferred approach. However, this year they were on a different type of mission and would not leave.

We had very small ants, but probably thousands of them walking an ant trail along a path in our kitchen. I originally wanted to buy these baits because of the reviews and the idea of the sugary liquid bait made sense to me (put a couple drops of a sugary pop drink on the floor and the ants would likely swarm it). However, we have a cat and i was concerned for her safety.

Ultimately, we bought a different brand that did absolutely nothing. Along the ant trails, the ants would go through these baits giving a little hope at first, but the numbers did not decrease. After a week and a half of no results, i bought these baits and put a few where we can see them come into the kitchen. I covered the baits with a box and put almost 60 pounds of weights on the flaps to prevent our little one from getting to them. Fortunately, she was interested for a minute in the box on the floor (typical cat 🙂 ), but otherwise left it alone.

First, the results were quick in one way. The baits immediately attracted the ants and there was a massive decrease in the ants along the previous ant trail. After an hour, i actually took the weights off and looked and they were absolutely going nuts over them. I replaced the box and left the baits alone for about 4 more days.

Now, the ant problem seems to be finished. I have subsequently checked the baits and i have seen only a few still walking around them. I am leaving them for a little longer to hopefully complete the job.

Two notable observations. First, opening the baits is tricky. The instructions make it look like they tear right open, but that really was not the case. I had to work pretty hard to open them and then the entrance was all jagged etc. Next time, i will see how they open with scissors. Second, from my previous inspection, the ants have tracked a lot of the liquid solution out of the trap. Nothing can really be done about this from the manufacturer, but just a warning to those who use these. Maybe consider putting the traps on something if you are worried about your floors or other surfaces these might go one.

All in all, i think they give you a decent number of traps for the money. We have leftovers for possibly another ‘invasion’. I also am very pleased on how fast the results were. Almost immediate change in the numbers due to the attraction of them to the bait and abandoning the ant trail (minus a few headstrong soldiers) and pretty much clearing up the issue in about 4 days. In my opinion, the manufacturer claims are legit.

First, this is an honest review. I am not getting paid to write this review and don’t know anyone connected to the company (unlike some people who write product reviews).

We had several carpenter ant nests in the walls of our house and saw about 10-20 ants every day. So, we tried terro liquid, amdro crystals, hot shot brand boric acid, amdro crystals mixed with powdered sugar, boris acid mixed with powered sugar, boric acid mixed with sugar and water (which has worked for us with other types of smaller ants) and we tried all of these at the same time. The photos show carpenter ants feeding from the terro and boric/sugar/water mixture (but none of the other baits we tried). It took about 2 months (much longer than we expected or some reviews report of 2-3 weeks), but now we haven’t seen any carpenter ants for one month.

The terro without question was the best of all these options. The 2nd best (and the only other bait we ever saw taken by the ants) was the boric/sugar/water, but it quickly dried up each time within a day or two so we stopped using it after a week (and because the ants kept eating the torro). The torro’s small opening kept it from drying out even after 2 months.

Because of having several nests we used 9 terro bait containers, put them on a small piece of aluminum foil to catch the liquid that runs out very easily and is very sticky. Every few days we replaced the foil underneath the torro bait as well as poured some liquid out onto the foil to help attract more ants. Some internet info says this product might not work for carpenter at certain times of the year (when they’re not feeding on sweet things) or in certain regions. The other baits we listed may have helped some, but we never witnessed carpenter ants taking them, but we always saw ants taking the torro and boric/sugar/water. I’d highly recommend trying this. If it doesn’t work then try it at a different time of year (we are in the southeast usa and used it july, august & part of sept) or try with a combination of the other baits mentioned above.

About two months ago, it all started out with a couple of recon ants on the kitchen counter.

I squished them and thought that i was done. They were literally the calm before the storm.

Over the next week, the trickle turned into a flood of ants. I carefully sprayed with raid, in the corners of the counter. Not very effective.

I was ready to drop some coin on a professional pest control. But then i decided to log onto amazon and see what they had to offer.

I bought the raid ant trap and then, at the last moment, added this terro brand, to the cart. I never heard of terro before, but i figured, “why not buy both?” it’s way cheaper than the pest control company.

I have to say that i am so glad that i purchased both brands. It turned out that the ants, that were raiding my kitchen, absolutely loved the terro product.

As i was setting out the trap, i accidentally spilled some of the trap’s clear fluid on the counter. I was going to wipe it up, but decided instead to leave it, to see what happens.

It became very clear, over the next hour, that the ants really liked this stuff. They formed a ring around the edge of the spilled pool of sugary water, containing chemical x. Actually, chemical x is just borax. Relatively benign for us. Pretty darn effective on ants.

Anyway, it was nice to know that they liked it so much that some of them engorged themselves. Their abdomens were visibly swollen as there went back to the colony, to share in the fruits of their labor.

Within three days they were almost all gone. I left the trap there for a few more days, to feed any stragglers. By the end of the week, they were all gone and even after two months time, they have not returned.

I am still amazed at just how effective this stuff is. I saved a bundle of money and it worked in three days. What’s not to like?

As long as you have the patience to wait a few days, i strongly recommend this highly effective, ant control product .

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.

A friend recommended terro and the first product i bought i thought was going to be something like this, it showed a rectangular shaped bait trap, but when i opened the box it was flat. I was supposed to fold along perforations and create the rectangle shape. It never worked right. I couldn’t get it to fold. I tried using them in their flat form, in corners and along the floor but i didn’t see a single ant attracted to it. I then tried the hard plastic terro bait traps that come in groups of 4. Those are designed to stick, by adhesion strips, underneath cabinets or on the underside of anything. I had good luck with those, i saw large trails of ants being attracted and a decrease in ants after we put them out. After purchasing 2 packs of those i saw these clear plastic ones by terro are a better value. You get 12 packs for only a little bit more than the 4 packs and there appears to be more ‘bait’ in each one.

These worked the best yet. Probably because we have enough of the to put everywhere and also because we started addressing the problem already with the other products. On the downside the tab is hard to twist off without spilling the product. I suggest you not even try. Hold it vertical and use scissors. Even so, you might get a little sticky on you. These probably won’t work if you have children or animals that will find them, you’d have to use the hard brown plastic ones. But if you don’t have either – these are the best!

I never had an ant problem but with this recent heat wave we had (southern california) i ended up getting ants all over my house!!! Just scattering in the bedroom, bathroom, kitchen, living room, doorway, everywhere! When i opened amazon to buy ant bait, this was the first product that came up so i immediately went straight to the reviews and bought these without noticing any other brand. When they finally arrived, i opened one up. They are a little tricky to open, use scissors! I placed one on the kitchen counter since i had more ants there out of anywhere in the house and i have cats and a crawling 11 month old so i can’t leave these on the floor. They come with 12 baits so i placed 3 on the counter and an hour later, there was an ant party on my kitchen counter!! It was a mess! But knew i just have to be patient. All the ants were now in the kitchen and not everywhere in the house which was a huge plus. No more ants in the cat bowl! In 24 hours, the trail of ants stopped. They were all gone! And swimming inside the bait! There were a few scattering around the counter. So i cleaned it up, threw them away and opened up a new bait to get the remaining survivors. By day 2, every ant was gone!! Buy this!!

Woke up to ants on my kitchen counters one day. Not sure what kind of ants but they were black and tiny. They came from my dining room window and marched a path to my countertop where i had some sticky stuff. I cleaned up my kitchen, clorox wiped my countertop and the ant trail on my cabinets, and swiffer wet wiped my dining room floor. I did not wipe the wall where the trail started from my windows so they still had a scent to follow. I got the terro ant bait same day delivered and placed 2 at the base of the wall where the ant trail met the floor and watched as the first ant eventually found its way into the bait container. After it brought the deadly nom home, 3 more came out. Within an hour a stream of ants were marching back and forth between the window and the bait. They were having a feast! Their last supper, if you will. The next morning, that stream of ants was mostly gone. There were a lot of dead ants in the containers and on the floor. They partied so hard that one of the containers spilled bait onto the floor along with a bunch of dead ants.

I cleaned the floor since i didn’t want the bait to get stuck and damage my floors. Over the next 3 weeks, there were maybe a dozen straggler ants each day still getting bait. I went on vacation for a week and when i got back, there were no more ants.

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!

The way these work is you cut one end off of the bait and then lay the container of liquid down somewhere the ants will find it. Within a few hours or maybe a day, ants will be swarming the bait and drinking the liquid. Some of the ants will die and be carried away by other ants. Some ants will lose their sense of direction and start wandering around aimlessly. Eventually, they will consume all of the liquid and carry all dead ants away.

The ants become disorganized enough that they stop focusing on whatever it was they were eating in your house. The infestation dies back a lot, or completely, as the bait gets used up.

My family and i continue to buy these.

I read a review where it said the problem is worse before it gets better. That’s an understatement.

Every ant on your block will come to this ant bait trap and you have to leave it there and watch them. It’s the scariest thing you’ve ever seen in your life. Kind of like alfred hitchcock‘s the birds. But once they all collect up they go right into the trap and there you have it. 30,000 ants just disappeared. Even your neighbors will thank you. This has happened twice in my house now. It’s unbelievable. And the ants apparently disintegrate in the trap. So just be real careful because my puppies were really interested. I had to make sure that i put it in a place that they could not reach. But it does the job. It’ll take between six and 12 hours. Just be patient. You start out with ten ants you end up with 300,000 dead ones !!!

Overall these ant traps work better than any others we have tried over the past 30 years in california. This latest model is a bit hard to open/break off its tab with just your fingers (a previous model required scissors to open and using scissors is still easier for the current model). These traps are relatively nontoxic to other living things. You must be patient as they will not kill off all the ants that quickly — it takes a few days. Also some ants (particularly the invasive argentine ant in the us) may have multiple colonies and after killing one colony another can discover the trap so during ant season it could take a week or two to clear out the nearby colonies.

If you want to reduce plastic waste and save money, you can also make up your own ant killing bait using borax and sugar water and a shallow dish. The terro ant traps are more convenient and covered and a bit less messy.

These work, but you should know that once you put them in the house, there is a mass influx of ants near wherever you put them. They disappear after a couple of days, but that first wave is pretty scary. They are attracted to whatever is in these things and they go back to the nest and tell the others and everyone comes down to join the party. The idea is that they take the poison back to their nest and i guess that is what they do. Have to follow up periodically if you start seeing the again.

I never have ants in my house except during the hottest times of the summer. When it’s 107 outside, i guess ants need their air conditioning, too. When they are here, they are definitely here. These traps are excellent and really take care of them. The only complaint i have is that they are difficult for me to open. You have to twist off the plastic (there is no cap). I’m 53 y.o. And may have lost some strength in my hands (who knows), but i still think that it might be difficult for a lot of women to open the little bottle. I used scissors to open one of them, it spilled out, but the ants didn’t seem interested. They were really interested when i could open the bottle correctly. I’m giving it a four star because of the easy of use problem, but otherwise it is a five-star product !

I live directly over a damp basement that appears to host some kind of ant colony – possibly carpenter ants. They’re about 1/2 inch long, black, very fast, and mostly out at night. I see 2-4 ants a day in the kitchen and bathroom and have had them crawl on my arms and even into my hair as i worked in my office. (!!!) i had little hope this product would work on carpenter ants but tried it anyway. I’ve yet to see ants actually at the bait stations, but since i put the bait down, i’ve only seen 3 ants in 6 days, and all acted like they were ill: 2 sat still on the wall for a long time, and 1 was out during the day. So the bait appears to be killing the colony slowly, and it’s a huge relief not to have to spend every night on a bug hunt!

The formula in this works really well
and honestly you can make it yourself with water sugar and borax
but it’s easier to buy this formula already made

the one thing you need to know
is that this packaging does not attract ants
and also the syrup that drips out
will create hard glue like spots on your floor or counter

so what i recommend you do
is save some slimmer cardboard
more like card stock, less like a thick corrugated box

when you need to use terro
cut up some pieces of cardboard big enough to pour the syrup and have room for ants to get on it

place a few of those in the area where you see the ants
walk away; don’t disturb it

if it’s the kind of ants that want sugar they will find it
and they will swarm the cardboard and eat up all the syrup

don’t use paper plates
the rim is too high for the ants
yeah they’ll get there eventually
but
you want it real easy for the ants to smell, sample, and tell their friends
so don’t add complications
just use some thin cardboard

in a day or 2 or 3 they will all be dead

if you just cut the trap open and leave it out
rather than pour onto cardboard
you got about a 1 in 20 chance that the ants will find it
and if they do: the opening isn’t large enough to get the colony feeding

if the ants don’t respond to terro: call a pro for advice

There is no denying that this stuff works. I buy it all the time. My wishes: make it easier to open and less prone to leaking. But if you want to get rid of ants, this does the trick every time. I just hate the mess when it spills and i struggle with opening them.

The idea that you can open these effective bait stations by ‘snapping off a plastic tab’, is ludicrous. You will need a scissor, unless you are freezing these before hand. Since i don’t freeze my ant bait, i get out a large sharp pair of kitchen scissors and carefully trim off the ‘snap-off’ part. I don’t want to spill the bait, or remove a finger when the plastic finally surrenders to the scissors. Attempting to snap off will leave you frustrated and finger cut when/if you can finally break the plastic (this is all a guess, since i would never be so stubborn as to keep trying to twist off something that now has an exposed sharp edge…). Come on terro, some truth in packaging please. You have a good product!

At first the ant population explodes then after a few days they are gone. Just somewhat hard to cut open to give the ants access.

The first time i put it out in my kitchen i came back and saw a herd of ants.i immediately forgot everything i read on the package and killed them all with spray.they began to congregate again and i followed directions and allowed the ant train to continue.2 days and hundreds of corpses later i am ant free.super gross but super effective.will foist on anyone who asks me about ant killer.the trickle of terror is ovah!

These baits are very effective. Maybe it’s just me, but i have a very difficult time opening them.
