Little tiny ants have been spotted in our new home, and many people are suffering the same fate across the country. Diatomaceous Earth (DE) works well … use food-grade not swimming pool DE. It should be sprinkled around the perimeter of your new home and you can also safely sprinkle it inside where you see them. Do not wet the DE or it will not work. DE isn’t an instant kill but should resolve the problem within a week or so.
