According to the manufacturer, a single application can eliminate carpenter ants, fire ants, and over 20 other ant species for up to three months. A 24-ounce container of the bait covers 1,080 linear feet, which should be enough to cover the perimeter of an average-sized home six times. However, it's worth noting that we found the instructions on how much was needed to be a little unclear, and had to resort to a trial-and-error approach.Īnts are lured to the granules because of their food-like odor and are killed after returning with the granules to the colony. To create a bait barrier that will deter ants from entering your home, Amdro says to shake a band at least a foot wide around the outside of your property. However, you will need to keep it far from pets. But if spilled, we noted that unlike other ant killers we've used, this product doesn't have a strong smell and it's not sticky when poured. We found that the sprinkler side is easier to control. You can choose from two options for pouring out the ant killer: a sprinkler-style side and a spout. While we saw an ant or two during two months of use, overall we were impressed by this product's effectiveness and ease of use. To test this product, we used it to surround the entire perimeter of one of our houses in Portland, Oregon. We chose the Amdro Ant Block as our best overall pick because it can provide a permanent fix by eliminating the ant colony and queen completely, as well as prevent ants from entering your home in the first place.
