My right foot and I both hope this works on fire ants. I used to get them in my raised bed, esp. if I had something covered. The only thing I felt save using was there was boiling water and orange oil. While the boiling water killed most of them, the orange oil just made them move to another spot. With all the rain we are having, they are especially bad right now. Our neighbor suggested a new product (new to us). If it works, I will post it. First, I have to make sure it is safe for bees.
