Fire Ants in the Butterfly Garden
I'm allergic to fire ants - one bite won't kill me, but if I get too many at once it's another matter. So, I'm extra careful about keeping the mounds out of my pathways in my yard.
Unfortunately, they have decided to form their spring mounds in my butterfly garden.
Is there anything I can use to keep the mounds out (so I can weed and look after my plants) that won't harm the butterflies, caterpillars, or eggs?
I am adding step stones to try to provide somewhat safer places to put my feet, but the ants will still react if the foot on the stone disturbs them or if I pull a weed growing near them.
