It’s been a terrible year in California for black ants. They have invaded my kitchen, my bathrooms, and my home. It has been awful. On morning I came into the kitchen and found ants on the counter. In frustration I grabbed my peppermint essential oil, dropped two drops on the counter, and used my hand to rub it all over the counter where the ants had not ventured. I watched the ants go up to the border, stop, and then change directions. I used my finger to draw a peppermint circle around a few isolated ants – they were trapped in the circle. Finally, I rubbed the entire counter with one more drop of peppermint, and the ants have not come back. I will gladly rub my counters down with peppermint one or two times a day to keep the critters from invading my territory again!
