Description

Kill outdoor ants before they make their way inside with Amdro Ant Killer for Outdoor Home Perimeter, an ant control product for homeowners. This ant bait outdoor formula is designed to surround your home with a band of protection as an outdoor perimeter bait around the house perimeter, around the foundation, or the lawn perimeter. This dual-action bait attracts and kills listed common ant species and keeps working for up to three months. Foraging worker ants think the ant bait granules are food and carry them back to their colonies. Shared with other ants, including the queen, its ant-killing power goes to work. Expect to see fewer ants within one week. When the queen is dead, the mound dies! Use any time ants are active during spring or summer for home perimeter treatment and outdoors in the yard.

It works and didn't even take long!
Size: 12 Ounces
It goes against my morals and principles to "kill" a tiny life that just happens to be in the wrong place at the wrong time. I usually try to save insects by gently capturing them in a tissue and letting them go free outside. With larger ants, that is easy to do. Even a slow fly can be saved, (they are rarely slow, though!), if you can get it in time. But those tiny ants are next to impossible to save. They are just too tiny. So, in this case, I had to choose the quality of MY life & the family member I live with over these tiny little innocent creatures who were simply looking for food in the wrong place. This annoying ant infestation was in the kitchen on the counter! These tiny little buggers were just where you prepare your food, on the counter near the sink. I've never used a product like this before, so this was a new experience for me. However, it is so annoying and disruptive to one's quality of life to deal with ants in their kitchen. I had to submerge my morals in this case. I carefully controlled how I spread this product outside right where the ground meets the house, putting down enough but not too much. That was fairly easy to do with the lid that come with it. I put it all along the permimeter of the entire back side of the house, not just under the kitchen window. The very next day, there were no ants in the kitchen! I couldn't believe it. I thought it had to be a fluke. I was waiting for them to appear the next morning. They did NOT. This stuff really works! If you have an ant problem, do not think twice about buying this product. It is effective and will give you your peace of mind back! ... show more

Great

Ants kept finding ways into my house and none of the sprays, gels, baits I bought helped at all. They just moved to a different place. Used this once and haven’t had a ln ant problem again! Definitely will keep this on hand every year. It is not pet safe, so you do have to keep that in mind. Instead of placing this around the exterior of the house, we got under the house and placed in around the edge underneath where our pets can’t get. ... show more

This Stuff Just Works. Get Some!
Size: 24 Ounces
This pesticide is the real deal. I have been applying it about once per month along my exterior perimeter walls, and the ants inside the house have gone away completely. I know when the pesticide is no longer effective when I see tiny baby ants near the kitchen sink. The price per bottle is more than fair and compared to a professional service that would probably charge hundreds for the same treatment, this DIY pays for itself over and over again. Seriously, it is easy to apply and only takes a few minutes of your time to spread the pellets. I usually have some left after a full perimeter application, so I usually spread the remainder at the front of the house in the garden/shrub area. After two full applications so far this year, the amount of complaining I've heard about "we have ants again!" has dwindled to zero. At this point I've put a calendar reminder on to order it monthly and apply whether I see ants or not. If you're paying a company to spread ant killer, you may want to try this approach to see if it works out for you. Glad I tried it and saw success. ... show more

Works great

This ant bait works really well and is easy to use. The gel is simple to apply where needed, and I noticed a difference in the ant activity after using it. I like that it can be used both indoors and outdoors, and a little goes a long way. It’s also convenient for getting into smaller areas where ants tend to show up. Overall, an effective and easy-to-use ant bait that I’m happy to keep on hand. Dries well and quickly, isnt messy. And you get a good amount ... show more

This works!
Size: 24 Ounces
When reading the reviews I saw someone posted a video of the ants carrying the granules away. I was a bit skeptical, but decided to try this anyway based on the reviews. To my surprise, the moment I sprinkled this in the path of the MANY ants we had coming into the house from the yard/ne mulch. Within seconds I could see them carrying the granules away. About 2 days later they were gone. It has been over 2 weeks and still no ants. We had them all over the house too, not just one area, so I am really impressed and hoping this will last a while. ... show more

It works! And quickly!

I've fought ants all summer with multiple methods & none phased them. I put Ortho out on a Friday afternoon in small amounts in the most infested areas of my yard & the ants immediately picked the granules up & began carrying it into their dens. Within 24 hours all their populations had decreased by at least 80%! I'm quite pleased & highly recommend the product! ... show more

Works in one application!

We “had” a terrible ant problem in and around our gravel and stepstone walkway in our backyard. We tried so many different products over the past couple of years and nothing worked until now! This ant killer is amazing and worked with only one application. I highly recommend it! I am so glad we found this product. ... show more

Attracted more ants

I really don't know how well this works. I put it around the perimeter of my house and the ants went wild. Idk if it's bc they see a "food source" and would've died from it but I immediately had millions more no exaggeration. I am now signed up for routine pest control which is working great.
