From the manufacturer


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.

Product Description
To kill common household ants, simply place TERRO Liquid Ant Baits stations near indoor areas where ants are spotted. Ants enter the trap, consume the liquid ant bait and return to the nest where they pass on the bait to the rest of the colony. TERRO Liquid Ant Baits are specifically formulated to allow worker ants to consume the product and survive long enough to carry the liquid back to the nest and deliver a dose to the rest of the colony . The liquid ant bait stations prevent the bait from drying out and provide the ants with a continuous supply of liquid, day and night. Monitor the baits regularly for activity, but do not interfere with the ants or baits. Replace with additional baits when the first set is depleted. Depending on the size of the ant infestation, complete control may take up to two weeks.
Recommended Placement : Along baseboards In corners of rooms and cabinets On countertops Under and behind appliances Under sinks or around pipes and water sources On windowsills and around doorways Near garbage cans Along ant trails.

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.
Most effective baits I used to get rid of my infestation:
TERRO T300B Liquid Ant Killer, 12 Bait Stations (make sure you have scissors to open these, the tabs suck)
DIY - Mix Powdered Sugar with Baking Soda, put it in a baggie or a lid
DIY - Mix Borax (1.5 tablespoons), Warm Water (1.5 cups), and either sugar (0.5 cup) or some peanut butter. Mix well, and then soak a cotton ball into the mixture.
^for this one, I used peanut butter, since I had already set up the baking soda/sugar trap.
For all of these traps, you are going to want to place them somewhere near the entrance of where the ants are coming from, out of reach from pets and children. After a few hours, you should start seeing more of them show up. This is because they are hastily working to bring the "food" that they found an abundance of back to their nest. Don't mess with the traps or squish the ants once they start doing this, they are delivering poison to the nest. You can continue killing the ones that are not collecting the bait (e.g. ones that are just wandering around your house--they are either lost or scouting, no reason to keep them alive). Just make sure you throw the dead ants away, so that they don't attract more ants over with their pheromones.
If there are locations the ants are falling from, I'd recommend mixing water with dish soap in a (preferably) rectangular bowl with skinny edges, and then placing that under the drop point. This mixture will paralyze the ants and drown them as soon as they touch it. You NEED to use soap--carpenter ants are very good swimmers if the water is not tainted (Dish soap is toxic if ingested, so do not let pets or children near this mixture either).
Ants change their mind on what they want to eat every so often, so I'd recommend using all 3 of the baits I listed if you want to get rid of them as fast as possible. If they are not taking any of the 3 baits, there are 2 possibilities: 1) It might be a bad time of the day for them--ants are generally most active at night, and early in the morning; or 2) They are in their mating cycle and have no interest in eating anything. The only advice I can give you for this is, just leave the traps where you had them and wait for them to finish the cycle. If you see winged ants, SQUISH THEM. They are breeders, and they do not collect food.
One last piece of advice: Carpenter ants make satellite nests. Their main nest is most likely not in your house--there is a good chance that it is in rotting wood (trees/logs), or in the dirt somewhere near your home's perimeter. Because of this, I'd also recommend looking for an insecticide spray that you can apply to the perimeter. I used "Spectracide Terminate Termite & Carpenter Ant Killer", and while it does work, I would suggest looking for a different one. Its spray pump is VERY annoying to use, and it is electronic, so there is no getting around its tediousness. Just make sure you read up on the insecticide's proper usage before applying it (most of the companies will have a website for this).
I hope you found my advice helpful. It took me over a month to get rid of my infestation, since I initially had no clue what I was doing, and was just blindly ordering baits. I felt hopeless, and eventually I called 3 different exterminators... they all tried to get me to do a 1-year "maintenance" contract with no alternatives (over $700!). I spent about $95 trying to get rid of these things by myself. Over half of that money went towards useless bait that they did not care for. If you follow my advice, you will probably be spending under $50.
Good luck!

The only odd thing I saw was that in some of the packets there were floaty bits and in other they were crystal clear, I’m not sure if this is a defect but I’ll still use the remaining packs in the future.
