Fire ants all over pepper plants!
I need some advice on getting rid of a fire ant infestation.
I have several 4x8' raised beds (over caliche rock, pretty much - I'm in south central Texas) and we've been under extreme drought. The only place I've found fire ants this year is in my beds. :( No visible mounds - they seem to be coming up from directly under my pepper plants. They leave everything else alone except for the peppers, but it is to the point that I can't harvest a thing because of the density of the ants. I have tried Orange Guard, which will get rid of them for the rest of the day but they're back in the morning. I have tried spraying molasses as a deterrent with zero luck. I can't treat the garden perimeter with something like Amdro, as I'm on a slope and any rain we get (ha ha, fat chance) will wash it into my planting area. Any ideas on garden-safe treatments to get rid of these nasties?
