Hi all! I"ve been growing japanese maples in pots for several years now. During 2006, I found that red fire ants had began mounding in several of my pots. At that time it was just a nuisance, however during my latest round of winter repotting, I found that ants had taken up home in several more of my pots. I have not yet seen any apparent signs of damage from the ants, but I an fearfull that eventually there will be. I've tried to get rid of the ants by using "Bengal" ultra dust fire ant killer, "Spectracide" fire ant preventer, and another brand that I don"t remember. To date, Bengal seems to work best. Has anyone else had this problem? If so, what have you found to be effective in permanently getting rid of the ants? Since maples contain sap, will the ants eat developing roots? Also, will the pesticides harm the maples if not used appropriately? Thanks for any advice.
