Looking for suggestions on getting rid of ants

Diatomaceous Earth (Fossil Shell Flour)- our house is on a concrete slab - along with various bugs which we don't mind, the tiny ants start to appear in the spring into summer in various parts of the house as well as the outdoors along the side of our house. I sprinkle the ants and their trail with the powder and they disappear within a short period of time. Works up here in Canada - it can be found in garden stores as well as pet supply stores.
