Review: Good-bye fire ants..........! - It works really well. Kills the whole mound and the queen as advertised. I dug into the mounds afterwards to see how effective and no ants or movement. Helps me keep the yard safe for my mother who likes to garden. Poor woman was being bitten all the time and no longer wanted to care for her plants. This helped. Don't know how long it will last yet. We shall see. ....Edit 05/01/26...While it works well and kills the mound, I am not able to keep them from coming back. It's like playing wack-a-mole. Still, a good product.

### ⭐⭐⭐⭐⭐ Knocks out imported red "fire" ants
*by W***E on May 10, 2026*

I have used Orthene for years! It decimates a bed of fire ants in a few hours. Do not disturb the mound, apply it on the mound and around the perimeter about 6" to 10". It is a great contact killer. You can see them getting all "herky-jerky" once they are exposed to it. I recommend apply it using gloves and in calm conditions. It is a powder and will be harder to effectively place it if windy. The light dusting will get them coming out - then the countdown is on! I try and pound them after some rainfall and they are on the move. You won't kill 'em all, but you can get them moving outside of your property line. Good luck because they are vicious little guys!
