What is Amdro Ant Bait?

Amdro Ant Block is an exterior granular insecticide that kills 25 species of ants when ingested. To get rid of ants, apply the ant killer around the perimeter of your home with the convenient shaker bottle. Ants mistake it for food and carry the insecticide back to the colony. When the queen and her subjects eat the poison, the colony curtains. The active ingredient is a slow-acting hydramethylnon and lasts for up to three months. It can be used outdoors on lawns, on ant nests and around structures.

The container is easy to handle and easy to store. Plus, you don’t have to mix anything or deal with messy liquids. The brands says you’ll see fewer ants within one week and it’ll take a month for the entire colony to be destroyed altogether.

How to Use Amdro Ant Bait

Sprinkle a 1-foot-wide area around the perimeter of the house with the Amdro ant bait. Look for nests and trails where ants travel, and avoid applying the pest control product when heavy rains are expected. Then, wait for the insects to find the insecticide, which they’ll think is food, and bring it back to their colony. Voilà! It’s only a matter of time until the critters are gone with the low toxicity solution—no ant exterminator needed.

The Best User Reviews

Ready for a solution that actually works? These reviewers are raving about the power of Amdro ant bait.

“We have crazy ants in one corner of the house for some reason, and we have tried everything from foggers to home remedies,” shares five-star reviewer, PrincessInMs. “I sprinkled this outside, and even though the label says it could take from one to four weeks to work, it worked much faster. I sprinkled it out on Sunday and by Tuesday there were very little ants outside and none inside.”

Carol, a verified purchaser, writes, “This is the only ant killer that ever made a difference in my yard. It took a little bit to work. I guess that is because it is bait that gets carried to the queen ant and then ends up destroying the entire mound, but with a little patience, it did definitely work.”

Literally went from ants invading my house to zero ants within two days. I watched the ants on the porch picking the granules up to take back to the nest,” confirms Sherry, another five-star reviewer.
