Several years ago, I lived in a basement of a four-plex and in the first (and only!) spring there, my roommate and I discovered thousands of ants invading our entire apartment. Her Grandma told us about using baby powder so we tried it, drawing barriers across doorways and around our beds, along the kitchen cabinets/stove/fridge , etc. It didn’t kill the ants already present but it sure kept them away from areas we didn’t want them. When my roommate went away for a week, we put everything in her room up high, leaving only her bed and dresser touching the floor, and generously sprinkled her entire room with the powder to keep ants out for the week. I checked her room every day and found no ants in there the entire time.

To prove the baby powder was helping keep the ants away, we wound draw (sprinkle) powder circle around a small group of ants and watch them try to escape. They couldn’t. and if they got powder on themselves, they’d crawl around all drunk-like for a few moments and then stop moving completely – the powder messed with their senses, for sure.

Now, about that borax, I’ve sent the hubby to assassinate quite a few roaches now that outside temps are 105+ and they’ve migrated inside. Time for a different approach!
