My wife and I were talking and she reminded me that we had some success with concentrated orange oil (Doterra brand to be exact). It was not cheaper than Amdro, but we switched once we started seeing the fire ant mounds in the areas our kids and dogs were frequenting. The orange oil destroys their bodies and kills them. You would have to mix a large quantity and drown the mound. But if safety for other organisms in the vicinity is paramount it’s a good option.Ok-I’m going to try the boiling water where I know my flock go for sure but will keep sevin dust in mind for outer ranges. Mounds are getting out of control for some reason so y’all are giving me plenty of options! If your chickens were fine, the sevin dust would be ok for ducks and geese I’m guessing?
