I cannot believe I battled ants in my home for two weeks using countless sprays. After reading these reviews, I went out and bought a couple boxes of Terro. Within two days my ants were gone! Don't waste time and try these first.

This is the first product review I have ever taken the time to post, but I feel obligated since the product worked so well. I had hundreds (probably more like thousands) of little black ants coming in to my house from all over (wall outlets, ceiling etc.). I placed a bait in each of the ant trails. Within 1/2 hour there were thick streams of ants going to and from each of the baits. After only 1 DAY there were no more ants! The best part is that they didn't even die on the floor. They all take the bait back to their home and die there (no mess for me). I left the traps out for a few more days just in case, but did not see any more ants. It has now been 2 weeks since I have seen an ant in my house. This stuff is amazing. If you have ants, you understand why I am so excited to be rid of them.

Our house was being invaded by masses of black ants. We'd spray and they'd be gone for a little while, but seemingly within minutes they'd reappear and swarm over our kitchen, in our bathrooms, and even over the floors! We tried Raid ant bait, and when that failed we tried another (black flag?). Both baits claimed to be "irresistible" to the little buggers. Yeah right. The ants never touched any of the other baits.

I found out about Terro on Amazon.com, and struck by all the good reviews and seeing as how I was just wasting my money on other solutions, decided to give Terro a try.

I set out the first bait in my kitchen in the afternoon. Nothing happened all evening. We were starting to have doubts when a scout ant inspected the Terro briefly and continued onward. We left the bait there overnight. The next morning, I inspected the bait again before I left for work... still nothing :( "Oh well, at least it wasn't too expensive".

That day at work, my wife called to tell me the ants were all over the bait! They came out in such numbers and went after the Terro with such enthusiasm that we kinda regretted putting the bait somewhere so visible. But I was happy to see ants finally taking bait. The absolutely loved the stuff. Ants piled up to get a mouthful of the solution and many were pushed into the tray by those behind them and drowned in the solution!
Fortunately, it seems enough of them managed to get back to their nest. In about 3 days we noticed a considerable drop in the number of ants we saw around the house. At this point we changed baits (the one we set out was all filled with dead ants) and set two out instead of one (The instructions recommend setting all the baits out at once).
Within about a week, our ant problem was effectively under control. We still keep a can of spray handy, and occasionally see a lone scout ant which we squish on sight. I highly recommend Terro to anybody with an ant problem. Other baits are junk. Terro works!

I cannot believe that after years of watching ants ignore baits, I tried this and the ants swarm to it. The downside is you do not really know how many ants you have in your home until you see them all swarm on this. BUT DO NOT KILL THEM! They eat it and take it back to their colonies.

The most persistent ant is the argentine ant. The reason is they work with other colonies unlike most ants who fight the other colonies. They also have ten queens per thousand unlike all other ants who have one queen to kill. Argentine ants have no known predator in the USA so they just multiply.

Terro is the only bait that can and will kill these. But it takes days and even weeks. In the meantime, it is gross as you start seeing dead and live ants everywhere until they all just die off.

This is the best ant killer I've ever bought. The ant's come running to this stuff. If you need an ant killer this is it. Don't bother looking anywhere else, buy this. In 1 to 2 hours you will see a trail of ant's that can't wait to take the poison to their queen.
