    Answer This Question

    This product is an outdoor ant killer granule bait designed for use on lawns, landscaped areas, or around structures to create a barrier. It works when ants carry the bait back to their colony. You can sprinkle the granules around the perimeter of your home or other outdoor structures. However, the instructions do not specifically mention brushing the granules into the cracks of deck boards. For optimal effectiveness, it is generally recommended to apply the granules as directed, allowing ants to easily access and transport the bait.

                  Amazing ant killer!
                  This is an amazing ant killer! I had three harvester ant colonies, they are worst then fire ants. i put it after 5pm and they were all dead the next day. Not even one left! I can't put a price on the product !

                    This stuff works great! Each spring, we are plagued with several large ant colonies that crop up in various locations throughout our lawn. I just sprinkle this around each opening in a colony, and typically by the next day, all activity in the colony has ceased.

                    Waste of money
                    Absolutely useless on carpenter ants. The ants walked right through several lines I put down. I even tried mixing some powdered sugar in it. Waste of money.

                      Ants Ignore This "Bait"
                      I have used this product and the Amdro fire ant killer. Neither is effective at all. The ants take the granules and pile them up like other sand granules. They don't take it into the mound at all.

                          Carpenter ants just kept walking past the bait. Disappointed.

                            Had a constant problem with tiny ants getting in the house. They looked like the little "sugar ants" that Terro liquid bait works on, but these guys move slower. Terro didn't work on them. I'd find where they get in, seal it up, but they would just find another tiny crack to get in over and over. I went to get granular diazinon I usually use around the home perimeter which works okay. Saw this and thought maybe I should get something specific for ants. I poured some of the Amdro on and around where I spotted a few places the ants were coming in. In 24 hours they were gone. ALL of them. This stuff works crazy-good and I didn't even have to use very much. Ants are out of my house!

                            Amdro Ant Block WORKS! You will see that it does INSTANTLY IF ANTS ARE PRESENT where you are dosing it. I noticed ants were entering my property through a pvc drain pipe at the base of my rock wall. I put down another brand of ant bait and also used a premise spray along their path as they traveled the rocks' ledge. A few days later when I came back to see if they'd been killed out--NOPE. Survivors were there again. I repeated the same treatment. No results. Today I sprinkled some Amdro granules in my hand and placed them directly in the ants' path along the wall and also on the runner of a fence....IMMEDIATE GRATIFICATION using very little product---Unlike the other brand of bait that was completely ignored, I could actually watch the ants sense the Amdro, change course and immediately go to it and either began to feed on it or carry it off. INSTANTLY. Ten minutes after beginning to write this review, I took the accompanying picture--one of the many feeding frenzies going on. I've used Amdro in the past and was happy with.....I have NO IDEA why I ever purchased another brand.
