  • Amazing
Size: 2 - 12 OZ Bottles Style: Mound Treatment
The best red ant killer ever. I have tried just about every red killer on the market, this really works. Within hours You could see it working, Checked on the mound the next day and it was completely wiped out. We are in the country with a lot of mounds, simple to use, Spread it over the mound and a little around it that is it. I have a lot of animals so I covered it with a large bowl Just to make sure none of the animals would lick it. Does have a kick of a smell when applying, but that was no big deal. Buying some more very pleased with the outcome. Worth every penny not to have to worry about red ant bites. ... show more

  • Works great, use responsibly
Size: 12 OZ Style: Mound Treatment
This stuff works incredibly well. Even less than the bottle says is needed, only a half tsp will wipe out a medium sized nest. The fire ants are terrifying here and I made the first significant strides in the battle against them when I used this stuff last year. Do NOT use this in your house. You should not be breathing it, and it smells terrible. Don’t use it in ditches or uphill from a waterway/pond unless there’s no rain forecasted for a while, and don’t use near a pond/river at all. It will kill important wildlife if you do. Per my research, a good several days to a week in the hot sun and soil will break it down and it will be okay, but fresh product getting into water will kill fish, toads, frogs, and maybe turtles. So please use responsibly based on how water flows near you and check the weather for rain before you use it. I treated dozens upon dozens of HUGE nests (like life-threatening to a toddler size nests) last summer with one bottle, so the bottle holds a lot of product. Price is wonderful for that amount. ... show more

  • Game changer
Size: 3 LB Style: Mound Treatment
Ortho Fire Ant Killer Mound Treatment works incredibly well! It’s easy to apply and quickly eliminates fire ant mounds, taking care of the entire colony, including the queen. I noticed a huge reduction in fire ant activity just hours after applying it. It’s also versatile, safe to use on lawns, ornamental areas, and flower gardens without damaging plants. This product has been a game-changer for my yard, keeping it fire-ant-free. Highly recommend this for anyone dealing with fire ant problems – it truly delivers effective, reliable results! ... show more

  • Yes!
Size: .21 oz Style: Mound Treatment
Does the job quickly and efficiently. We were skeptical especially with the price but it wiped out fire ants like nothing else we've found so far. Easy application, but you don't get a whole lot so being honest it's not exactly a value. Small amount kills mounds large and small and seems to kill those surrounding it that are connected as well. We will be getting more. Wish it came in bulk. ... show more

  • I was expecting a smell …
Size: 12 OZ Style: Mound Treatment
This stuff works pretty quick and well, however omg. I was expecting there to be a smell but it is so strong and lingering. It smells like spoiled milk.

  • This stuff works!
Size: 2 - 12 OZ Bottles Style: Mound Treatment
I recently purchased this fire ant killer, and I’m thoroughly impressed with its performance. After spotting a few mounds in my yard, I needed something powerful and easy to apply to get rid of these pesky invaders. This product did not disappoint. First off, the application was incredibly straightforward. The granules were easy to spread around the mounds, and the instructions were clear and simple. I didn’t have to worry about complex mixing or special equipment—just sprinkle and wait. Within hours, I started noticing fewer ants, and by the next day, the mounds were completely inactive. The formula works fast, which is exactly what I needed to quickly eliminate the problem without worrying about re-treatment. However I’m not sure if it is safe for pets or other plants. This would be my only concern if using around pets, kids, or a vegetable garden. In summary, if you're dealing with a fire ant infestation, this product is a game-changer. It works quickly, is easy to apply, and provides lasting results. I’ll definitely keep this on hand for any future ant problems. Highly recommend! ... show more

  • Stinks but works!!
Size: 12 OZ Style: Mound Treatment
I saw a few reviews before I purchased this and wow!! I definitely agree with those of you who said this stinks. It smells like old cabbage and sulfur and the smell lingers for a few days. The bottle is huge, a little bit goes a long way. Used this in the kitchen under the fridge and outside along the back door and when I tell you it kills bugs so fast.... I mean it. I haven't seen a live bug inside since using this. It killed the ants and junebugs outside and the little black carpet beetles I had inside. The bottle is still full. I don't think I'll ever have to use it again but if I do, I have plenty. Definitely recommend. ... show more

Size: 3 LB Style: Mound Treatment
I've had to use this product numerous times in my yard, and it does indeed take care of the fire ants as advertised. Even on the biggest mounts, as long as you get enough on there, the ants are gone the next day
