Key item features

  • Effective Ant Control: Attracts and kills all common household ants, including those you see and those you don't.

  • Easy Application: Apply drops of the liquid ant killer to cardboard tiles and place them where ants are seen.

My Summer Science Project!

I started working on ants in the dining room at a relatives house as soon as I got home from the store. I had to convince my relative that things look worse before it gets better. And did it ever look worse. This got the dining room under control in a couple of days. I still see a few going to th bait, and I refil/refresh it with a dot 2x a day. Then I noticed anys in a bathroom, just a few, but I thought I should bait it. I ended up with 3 pieces of cardboard baited in about a 10 inch span. Now, a couple of days later, after baiting it at least 3x a day (the dots of bait are completely gone!), the flow of ants isn't slowing down. I realized I hadn't looked carefully at the floor outside the door of the bathroom. There are tons of ants heading toward the bathroom. I put several tiny pieces of cardboard with bait on them all along the path outside the wall and out towards the front door. within minutes, the ants are stopping at the bait. They circle around the dot of bait. The whole family is into this now. We have se timers to take pictures so that we have some time lapse photos. I know how the system works, thats why I always buy this product. Now, 5 other people know how this works.

i use to see carpenter ants coming in threw the window so i set traps all over the and inbetween the screen and the window, i dont see them at all anymore. I also set traps of cardboard with just a drop on it like recommended at the front door and dont see them coming in from there either since i used this product.

I use several times during the year...

I do not use quite as directed because of our inquisitive furbabies. We had ants a bad infestation. I saw one come out of our floor vents. Peppermint oil did not help placed in the duct system. Having used this before I poured some in bottle caps and placed them in the vents. I haven't seen them in awhile. I use the ant traps at my son's house because he has no furbabies or children.
