Description

TERRO T300B Liquid Ant Killer offers an effective method for dealing with common indoor ant infestations. By strategically placing indoor ant traps around your home, you can attack the problem at its source. The liquid, which contains borax, is specifically designed to allow worker ants to consume the product, and survive long enough to carry the liquid back to the nest. Ants enter the ant bait stations and consume the liquid ant bait, transporting it back to their colony, effectively spreading the ant poison to rest the colony and the queen. The active ingredient in the bait slowly interferes with the ants’ digestive systems, killing the colony and the queen. Since this is a bait product, you will initially see more ants as they are attracted to the liquid – but don’t worry, this is a good thing. This method allows you to kill the ants you see and the ones you don't, providing comprehensive ant poisoning indoors. For optimal results, place the sugar ant traps indoors near areas of increased activity such as baseboards, corners, countertops, and other common ant pathways. It's important to monitor these liquid ant traps regularly, and replace as needed, as bait depletion and environmental conditions may vary. The ant inside killer offers quick and reliable results, reducing ant visibility often within just a few days. Be patient, as complete control of the ant infestation might take up to two weeks, depending on its severity. Using TERRO ant bait offers a sustained assault on ant populations, making TERRO ants killer indoor a trusted choice for ant control.

  • Impressive! Ants return to the hive eventually eliminating it.
Style: 12 Bait Stations
Wow!!! My cabin had huge issues and I needed something. I had used them before as a preventative measure and never saw ants leading me to think they didn’t work. They work insanely well! They’re worth every penny! They attract ants and you continue to put them out until there are no more ants. The ants love it and take it back to the hive eventually eliminating the hive. Clean and super easy to use if you take just one moment to read the instructions. Toxic to ants and conveniently packaged to the product doesn’t touch anything. The packages are conveniently small yet large enough for ants, hundreds of ants per container. Package contains enough for a major infestation. I will be leaving one or two around the back counter areas as a preventative measure. If you see nothing, they’re working. I have no idea how long they last but judging from my previous use prior to discontinuing them, it is a long time. I’m ordering more to have on hand. No ants typically means no spiders here on the mountain! ... show more

  • Works Like Magic — Ants Gone in Days!
Style: 12 Bait Stations
We had a steady trail of tiny ants coming into the kitchen no matter how much we cleaned. I set out a few TERRO bait stations in the main areas they were walking, and within minutes they swarmed to it like it was a buffet. Yes, it’s a little unsettling to see more ants at first, but that’s exactly how it works — they take the bait back to the colony. Within 48 hours, the activity was cut in half, and by day four, I didn’t see a single ant. It’s been weeks now, and our counters are blissfully ant-free. The stations are super easy to use, no mess, and safe to place out of reach from kids and pets. If you follow the instructions and let them do their job, these things are a game-changer. I won’t waste my money on sprays again — this is my go-to ant solution from now on. Highly recommend — just be patient and let the magic happen! ... show more

  • Fast & effective
Style: 12 Bait Stations
These worked really well. I usually make my own ant bait, but decided to try having some of these on hand just for convenience. These took about a day to work. The ants found them immediately and then the number of ants increased for a while before almost completing stopping about 24 hours later. It was super easy to use with the only downside being that this liquid will spill if you don't keep it flat after you open it and the little tab to open it is a pain to tear off. I ended up cutting the top off instead of tearing it because it's such a pain to open by hand. I'd definitely use these again though. Very effective ant control, easy to use, and cost effective. ... show more

  • These never fail - truly a great product
Style: 12 Bait Stations
I moved into a new home about a year and a half ago, and prior to that, my house had never had ants. At the new home however, there were numerous infestations in a number of places shortly after we moved in. We didn't have a lot of extra money to just call an exterminator (moving isn't cheap), so we decided to try a few different brands of ant traps, although with them in numerous places in the house, I was skeptical. The first two we tried didn't do much. Temporarily killed a few but didn't at all stop the problem. They'd be right back in the same spot. Then, I tried these and it's truly amazing how well they worked. Just put one down where there's a stream of ants, and typically in a couple days, the stream just stops. At first you'll see a large number of them crawling into the trap, but most won't stay there. The trap targets the whole colony and amazingly works every time. After putting a trap by every place the ants were streaming, the infestations stopped, and although we would have a new stream pop up every once in a great while over the course of the time we've been there, a trap always quickly stops it. The other day, an exterminator came to the house trying to sell us on their system to stop ants. It involved a spray under the house for $200, then another monthly spray after that, each costing $60. These come in packs of 12, and I finally used the last of them a couple days ago, so on average, I can eliminate ants effectively with these for 75 cents/month, or pay there exterminator $60/month. Hmm, I think these are a slightly better value. ... show more
