In the old days, farmhouses always had a lot of ants crawling everywhere, looking for food. Certainly people struggled hard to think up ways to prevent them and other small insects from crawling into the cupboard. Finally, someone intelligent had the idea of using water to solve the problem and designed a special vessel – an ant proof tray for the feet of the cupboard – that resembled a small round pool with a flat-topped round island in the middle. It was filled with water, so ants could not cross, climb to the cupboard, and eat the food. Only people who lived close to nature could have come up with such a natural solution.
Note: I would have added vinegar to the water tray to keep ants away!
