When we were vacationing in Mexico, our hotel room had tiny ants on the counters in the kitchen and bathroom, but I didn’t want to call maintenance to come spray insecticide. I have used peppermint essential oil to repel ants at home, but didn’t have any with me. However, I did have PanAway essential oil blend, which has peppermint in it. So, once a day I soaked a cotton ball in PanAway and wiped down the counters. I was happy to see it worked quite well to keep the ants to a minimum for our vacation week.
