TERRO T300 Liquid Ant Bait

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 terro liquid ant bait

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.


  1. Hold the bait station firmly with bait pack tab facing up. Break off the tab being careful not to spill the bait.
  2. 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.
  3. 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.
  4. Once ants are controlled, replace the baits every 3 months to keep them from returning.

  1. Lobster Dance

    I highly recommend these ant baits. They look a little More conspicuous than some of the “house” baits with the spiral entrances and such which originally turned me off to them. But, I will say that these are hands down the BEST baits I’ve used around the house.Some of the stand out for these baits is that they work fast. We had sugar ants in a few locations in the kitchen and within two (2) days of putting the bait down, they were cleared out. I put the bait down near the scout ants and within minutes they had diverted and a new line into the bait was formed. Just that easy.Another line of ants sprouted up a few days later in a new location, across the room, so I moved the bait and those ants also crawled in and started the buffet. Within a day that line was also gone.You can see in the pictures there are a few ants that die in there. Maybe drown or perhaps they are eating more than they can handle or coming back for more and succumbed to the bait finally. No matter, the other ants still went in without hesitation.The bait lasts a long time and was really effective. So, a great value for the cost. I bought the larger pack and have only had to use two to finish off multiple lines over a span a 2 months. And there is still liquid in the pack in case another line sprouts up through the summer.The only downsides I will say are the look, design and a lack of adhesion.The look just makes them stand out a little more than the ones that are solid color, can be stuck to the wall and have multiple openings. The opening is not flush to the ground and not being able to stick it to a horizontal surface wasn’t an issue, like I was concerned about, either. I had no issues with ants finding their way into the bait. And, honestly, once I got used to the look of the bait it didn’t catch my attention anymore than the classic, big-name brands we are used to.Removing the cap to open the bait is more difficult than just sticking one of the other brands to a wall or behind the fridge. But, once you have the cap off, you can place these on any flat surface without a problem. The ants are attracted to it more so than other brands I have used, drawing a solid line of ants, as if they were so excited they told their friends about the new food source.I highly recommend Terri liquid ant baits.*Not a paid review. Just a happy customer.

    I had to do it. I woke up one morning and discovered that my home had been invaded. They made their way into cupboards and cabinets. They traversed countertops. They openly mocked me in the way that only an ant could. I was humiliated. Dejected. Saddened. My humiliation and sadness turned into a blind rage. I needed to even the score. I wasn’t going to let them get away with this. So I devised a plan. I was going to poison them. Not a quick poisoning, but a slow one. One where they would unknowingly bring the poison back to their subterranean lair. So I put my sinister plan into motion. Bait was placed in the cupboards and cabinets, on countertops… Everywhere I could think of… It didn’t take long for them to find it. Their numbers swelled as more of them discovered my trap. They obviously thought that I was an idiot for setting up what appeared to be an all-you-can-eat syrup buffet. It was all for them. But I was the one that was laughing. I called them names as they lapped up that sickly sweet death nectar. I cursed their existence. I remember telling them to “just wait, you bastards!”. And so I waited patiently while they took the sappy and succulent sustenance back to their nest. After a couple of days, their numbers had dwindled. I would see a few here and there. They looked sluggish and drunk and I knew the poison had begun to take effect. I was giddy. Overjoyed. Proud that I had turned the table on the marauding intruders. Before I knew it, the ants were virtually gone. The few stragglers that were left were greeted with my middle finger. It was the last thing they saw before said finger squashed them into insect smithereens. The score was finally settled. I don’t think they’ll return. But if they do, my hands will be awash in ant blood once again.

    After the success I have had with this product I am never without a batch of bait stations on hand in case of ants.The first three times I had to use these they worked in about three days, even though the instructions say it could take two weeks. I never understood why the heck they give such a long timeline when it has always worked so fast for me.Then the last time I needed to use it, the ants did not go away in three days or even a week. It literally took the entire two weeks. But I have faith in the product and I was patient and it ultimately worked. I just had to deal with the ants crawling around a lot longer this time which was not fun. But I had to trust the process.I am not an entomologist so this is just a guess. But I suspect the last time took longer because there were much fewer ants present. The way this works is that the ants take the bait back to the queen and the colony to kill the ants at the source. So perhaps with fewer ants taking the bait back, it took longer for the bait to do the job. I don’t know, it’s a guess. But what matters is that the product ultimately worked and the ants are gone.This was also rated the #1 ant killer by the New York Times. I very highly recommend this for anyone who has ants.When deciding on buying something I greatly depend on reviews from others, so I hope this helps you!

    This is an easy, inexpensive, low-toxicity means of fighting off ant infestations. I use these bait stations in combination with the Terro liquid ant killer in 2-ounce bottles: https://www.amazon.com/gp/product/B0015031R8Be smart:1) keep areas free of other food sources — trash cans, pet bowls, food spills, etc.2) trace the ants back as far as you can to where the enter the room/cupboard/pantry3) place the bait stations on the ant trail as close to that entry point as is convenient — you don’t want it where it will get stepped on, disturbed/consumed by pets or people, or spilled on a porous surface.4) rubbing a little of the bait liquid around the edge of the opening can speed “discovery” of the bait5) once the bait is placed, you want to wipe out the ants that are already on the trail extending past the bait stations. I like to suck them up with a vacuum hose.6) finish by removing the scent laid along the trail by the ants. I use a bleach-based cleaning spray on tile, countertops, and vinyl flooring. For other surfaces, you might distilled (clear) vinegar but I don’t have personal experience with that.Most often, I supplement or replace the bait stations with the bottled liquid Terro. I put strips of painter’s tape down and put drops of bait along the tape. This is a much more economical way to deal with large numbers of ants.I understand the complaints about the new design, but I prefer it. The older design would spill sticky bait with the slightest touch. Ignore the “snap-off” description for the new design and cut it with scissors. Rub some bait on the outside edge of the neck where ants can smell it easily and they will find a way to get into the bait station (especially if you have been able to remove the scent trail beyond the station.You are outnumbered. You will have to outsmart them.

    We full-time in an RV and somewhere along the way, these tiny little ants started invading the kitchen. Ants so small that I didn’t think they were ants until I looked with a magnifying glass. I did some research and found an ant bait recipe online which I already had the ingredients for. But it was rather a hassle to make and I didn’t have good containers to put it in. These Terro baits have similar ingredients and folks in the RV world rave about Terro so I gave it a try. And so far, I haven’t seen a single ant. It’s been at least 2 months. I only put one out on the kitchen counter away from things. My only complaint is that I couldn’t figure out how to open the end without spilling it everywhere, so I cut it with scissors. When we moved to a new campground I put it in a baggie lying flat but it didn’t travel well. It spilled inside the baggie so I threw that one away and opened a new one. Since we stay at least a month at a time, it’s no big deal to change them out when we move. So far, so good!

    So I bought this because I spilled juice in a closet and the ants were nonstop! I bought 2 packs because I wasn’t sure if it would work. Boy, did it work! 1 pack was all I needed. I cut the end of the product (be sure to keep the product horizontal or at least try not to spill it out) and I set it near the entrance to the closet and within seconds the ants were like “hey guys there’s some other tasty thing over here!” And they started walking into the tube and dying! It was so fast and easy and in a day I picked it up and all the dead ants and threw it out. Super easy, no mess, no fuss just open, set and tada! DEAD ANTS! Most definitely worth the money and my recommendation.

    Day 1: I set out 3 traps in what I considered to be strategic spots around noon. By 8 pm, all 3 traps were completely swarmed/covered in Ants. I’ve never seen so many ants in my life. At first I wanted to just grab them all up, throw them away and get to vacuuming. But I left itDay 2: I check the traps again around noon, giving them a full 24 hours to do their work. I see literally 2 ants crawling around. No ants in the carpet. No ants on the walls. No ants any where else.Day 3: I can’t find an ant to save my life. Late last night, I even purposely left out an empty Dr Pepper can to see if maybe the ants just got wise and are avoiding these traps. Nada… not a single ant was left living.Day 4: The battle has been won. Only time will tell if the war will be as easily won or not.There is no other indoor ant trap that I can recommend as strongly as I recommend these. I have two dogs and a cat, and they don’t mess with the traps at all. They have 0 interest in them. These traps were extremely well, extremely fast, and are as easy and cutting the tips off, and placing the trap and walking away.They have no scent to them (that I can tell), they do spill easily though. It’s a thicker liquid, so it won’t just run over everything, but anything it does get on will be sticky.

    Once upon a time there were ants living within the impenetrable walls of an apartment. With three stories and 10 units to choose from, the colony had a plethora of places to hide and torment humans. One summer, the ants joined forces with a neighboring colony and their numbers became staggering as they entered residences through light sockets, nail holes and any crack or crevice through which their bodies could fit in each apartment. Babies cried, women cursed and men stayed out longer then they needed to to avoid the chaos. Times were great for the ants.Then, one day, a woman who had lived in the apartment for almost 10 years had absolutely had enough of the ant’s BS and took to Facebook to ask her human friends what to do. They, in unison, recommended TERRO ant traps. With the speed of Amazon prime she ordered the 6 pack of traps. To her surprise, the traps arrived faster than she anticipated and she feverishly tore apart the packaging to reveal the gift from the Gods.As an expert package opener, she dismembered and arranged the contents of the tiny box and decided where she would lay her deadly contraptions.With each location the human became more hopeful that she would eliminate her ant foe for good. Within an hour the ants came in full force for the trap in her bathroom. Through the cracks of the cabinets they descended in their masses to carry the seeds of death back to their beloved queen and families. Unknowingly carrying the contents of their own demise. Three days the ants marched tirelessly, undisturbed (as directed on the packaging) in their activities, and on the third day the final workers returned to bring the corpses home to their mass colonial grave, never to return again.GO BUY THIS!!!!! You too can win the Great War against the ants and regain control of your domain!!

    When I had a massive invasion of small ants in my pantry I used this product to eliminate 99% of them in 24 hours and 100% after 7 days. For my small ants the required technique was to cut the container and pour the sticky liquid onto an index card that had 1 edge taped to the floor so the ants could access the bait (i.e. sticky liquid). After several hours the index card was black with ants that appeared to be dead but were not because 24 hours later all the ants were gone having taken the bait back to their headquarters. A few ants (1 to 5) appeared daily until after about 7 days all the ants were gone and now weeks later none have returned. Do NOT use the product in this way if you have pets or kids that can access the sweet/sticky liquid bait. My ants however would not enter the bait container as provided – maybe they were too small or the wrong breed of ant?

    Out of nowhere I had an ant (tiny black ones) infestation in my restroom. I couldn’t figure out where they were coming from and killing the ones I would see did nothing. I got tired of seeing them so I found this ant bait. The day it arrived, I put all six around the restroom counter top where they were appearing but the ants were not interested in the containers. I accidentally spilled some while setting them up and within 30 mins the ants swarmed the spilled bait and within the hour the spilled bait was gone. They traced it back to the containers and that’s when I knew I got the suckers. I was then able to trace where they were coming from and squeezed more bait out in that high traffic area. The next morning (8 hrs later) I only saw one or two stragglers but I knew the bait did it’s thing. An additional 24 hrs later an I am still only seeing one or two stragglers which is good. To those complaining this isn’t an instant kill, that is not its purpose as this allows the ants to bring some back to their colony to share. This is a 24 – 48 hr process.
