Review: It Works! Eliminated Ants in 48 Hours Where Others Failed, Subscribe & Save - Wow! Put this stuff on Subscribe n' Save. I was at my wit's end with an army of small "sugar" ants in my kitchen, occasional troops in my bathroom, and recon in my office. They arrive inside our house whenever we are between seasons, especially when we have rainy days, followed by warm ones. Nothing makes my skin crawl as much as seeing ants in the house and I've tried everything - or so I thought - to get rid of them without success. Catchmaster DEFIANT Premium Liquid Ant Killer did solve the problem, and I'm so happy! I bought this kit which has the bottle of liquid ant killer and (4) open trays. You could use any shallow tray with this stuff in it and it would work out, but they do sell packs of extra trays too. I cleaned up the visible ants on my kitchen counters, then put out the DEFIANT in the trays along the area I could see the most activity. I put only a few big drops in initially, but didn't get many ants going to the trays, so I decided to add enough liquid ant killer in each tray to cover the bottom of the tray. This was key to getting more ants actively eating up the stuff and taking it away. There was a visible trail (I'd not seen before) of ants going to the trough and then back to their Queen (I'm assuming). For about 12 hours it seemed like I had way too much ant activity, but it was all around the traps. I kept them topped off, adding more liquid as needed. The ant highway slowed to a few within 24 hours, and at 48 hours I no longer see any ants and there is no activity at the traps. This stuff was effective and worked quickly. It is sticky, but there's no odor for humans. The trays are open, so they could be accessible to pets, which since we have a cat and dog was a concern. The trays are small and flimsy. If you run out, you could even use a plastic bottle cap or lid to a jar and it would work the same way. Whatever this stuff is, it attracts and eliminates ants in about 48 hours. The bottle is not a 1-year supply (my opinion), but well worth the price for pest elimination with very little hassle. I highly recommend it for apartments, dorm rooms, houses, offices, and areas outside where you can see ant activity.
Review: It Killed One Ant - UPDATE EDIT April 9,2025: I have been using this on and off since my initial purchase. Except for the first usage, where the ants [seemingly] showed utter disdain for the liquid ant bait flavor, it has proven to be very effective at its intended purpose. They now seem to love it. I upgraded my review to 5 star. Maybe it is an acquired taste. END OF APRIL 9, 2025 UPDATE EDIT UPDATE EDIT: Sep. 11, 2024 UPDATE: Today I found ants feeding on the Liquid Ant Bait. It has been 20 days since I placed the ant bait on my window sill, with the ants showing ZERO interest - until today! (I did not add any new liquid ant bait; I left the bait stations alone for 20 days with the original ant bait that I placed in them.) Now the ants were swarming around it like it was a feeding trough. (NOTE: I did add additional fresh ant bait AFTER the ants started arriving.) The video that I shared shows the ants shortly after I noticed them. The quantity of ants increased significantly after I shot the video, but I did not record any additional video. The ants fed on it for approximately 12 hours - a constant stream of ants coming and going for a large portion of that time. The ants eventually stopped and departed - every single one - even though there was still plenty of ant bait in the bait stations. There were no dead ants around the bait stations, which I found interesting. I also found it interesting that the ants just completely stopped coming. One other noteworthy item: I placed an additional amount of ant bait on the kitchen counter (near the stream of ants) without using a bait station (thus the ant bait was in contact with the counter and the painted kitchen wall). Some of the ants veered off of the main path to feed on this additional glob of ant bait. However, after all of the ants had departed, there were approximately 20 dead ants near this new glob that I had added. So it appears that the ant bait is effective. I updated my rating from a 1 to a 3. I just wish the ant bait had a more appealing flavor so the ants would be quickly drawn to it and gorge themselves. I believe that would make the product more effective. One more note: The product manufacturer contacted me, stating that they would like to address any issues or concerns - that customer satisfaction was important to them. I did not respond, but I did appreciate them reaching out to me. Thank you. END OF UPDATE EDIT I had a great opportunity to try this product today. I have had ants [intermittently] for a while now, so I ordered this Liquid Ant Bait. It arrived yesterday. This morning when I went to my kitchen, there were thousands of ants feasting on some banana bread and muffins that were in unsealed packaging from the manufacturer. After removing the banana bread and muffins, I put a little of this Liquid Ant Bait in two of the Bait Stations, positioned them very close to where the stream of ants was coming in (the wall outlet), and even brushed a number of ants into one of the Bait Stations (to help give them a taste). I left the 2 Bait Stations out for quite some time while there were still many ants roaming around, searching for lost pastries. The ants just basically ignored the Liquid Ant Bait. Even the ants that I forced into the Bait Station departed - along with every other ant in the kitchen - without so much as a second glance. Apparently, the ants did not find the Liquid Ant Bait to be nearly as delicious as the banana bread. I did, however, see one dead ant in the liquid ant bait. I think it most likely drowned when I pushed it and its friends into the Bait Station. I CANNOT RECOMMEND THIS PRODUCT AT ALL. I think it only killed one ant - probably by drowning.

## Features

- 1 LIQUID ANT BAIT BOTTLE (1 YEAR SUPPLY) + 4 STATIONS (2 STACKED): The DEFIANT liquid ant bait system comes with 3.38 oz of liquid ant killer - roughly a 1 year supply for the average home, providing you with year round protection from a single purchase. It also includes 4 bait stations that can be put together to make 2 covered ant traps. The bait stations can be refilled and reused season after season for as long as you have ants in your home.
- KILLS THE QUEEN AND THE COLONY: DEFIANT Liquid Ant Bait kills the queen and colony of most common ants inside and outside your home, effectively eliminating ant infestations. Confirmed effective against: Acrobat, Crazy, Ghost, Sugar, Argentine, Odorous house, Pavement & Little Black Ants. NOT EFFECTIVE AGAINST: Carpenter, Fire & Pharoah ants.
- FAST-ACTING FORMULA: DEFIANT starts working immediately, though it does not kill ants instantly. The formula allows the worker ants time to carry the liquid ant bait back to their entire colony and share it with other members, including the queen. Noticeable ant activity reduction within days, colony elimination can take up to 3 weeks, depending on the severity of the infestation.
- READY TO USE: Simply set the discrete stations where ants are seen and pour a few drops of liquid ant killer inside the bait station. Its transparent design allows you to monitor ant activity and liquid bait levels daily. Refill bait stations and place again as many times as needed. Rinse with water when done.
- THE ONLY ANT CONTROL SYSTEM THAT ADAPTS TO YOUR HOME: DEFIANT is a premium ant control system, and offers different station options to suit all areas of your home, indoor and out. For the most effective results, set baited ant traps indoor and outdoors near areas with ant activity - along baseboards, corners, & kitchen counters, targeting ant hotspots throughout your home. Snap two stations together for use in high-traffic or dusty places.

## Questions & Answers

**Q: Is it safe for pets and children?**
A: We always recommend following the product instructions carefully and keeping treatments out of reach of children and pets.

**Q: Do ants eventually develop resistance to its formula?**
A: Borax has been used as a reliable ant killer for decades, with no evidence of ants developing resistance. Borax does not cause instant death for an ant, giving them time to tell other ants where the bait is located and return the bait to the colony.

**Q: Does its bait remain effective during humid conditions?**
A: Yes, DefiANT ant bait works in humid conditions. Humidity can actually be helpful because it reduces the pace the that the bait dries out at. It is most appealing to ants in its most viscous form.

**Q: Do ants prefer this bait over other options?**
A: Yes, ants are attracted to the liquid in DefiANT Traps, often preferring it over other options. This borax-based bait is irresistible to ants. The ants consume the bait and share it with the colony, helping eliminate ants at the source.

**Q: Are there special instructions for cleaning the stations to maintain effectiveness?**
A: To clean the bait stations, wash with soap and water. Refill the bait station with Defiant Ant Killer Liquid and place wherever there is ant activity.

### ⭐⭐⭐⭐ Finally Found Something That Actually Stops the Ants at the Source
*by S***X on March 21, 2026*

After dealing with a steady stream of ants in the kitchen, I picked up the Catchmaster DEFIANT Liquid Ant Killer, hoping for something more effective than the usual quick fixes. I wanted something that would handle the problem at the source, not just what I could see. What stood out right away was how easy it is to use. The precision bottle makes it simple to place just the right amount without creating a mess. Within a short time, I noticed fewer ants, and over the next couple of days, the activity really dropped off. I like that it targets the colony rather than just the visible ants. It feels like a more complete solution, and the reusable traps are a nice bonus for long-term use. As easy and fast as it is to apply, clean-up is just as easy. I dripped a few drops, not paying attention to what I was doing, and clean-up was as easy as I could ask for. It’s a bit sticky, so use just a little soap and water on a paper towel if you need to wipe it up.
