Ants On Potato Hills

Q: How do I get rid of ants that make my potato hills their home? Are they
destroying my potatoes underground? 

A: Assuming you have fire ants, they are known to feed on potato tubers.
You’ll get the best organic control by following two steps: bait, then drench.
Scatter spinosad bait (Fertilome Come and Get It) on the mound and wait
twenty-four hours. Then drench the mound with d-limonene (Orange Guard
Fire Ant Control). This should give control for most of the summer.
