I went out one morning to see thousands of small black ants outside our garage door, where the car drives in, all along the edge of the door. My first thought was to get some insecticide and spray but I don't like killing living things no matter what they are. I read a post somewhere saying 20 Mule Team Borax makes insects go away. So I sprinkled some across their path and went to the grocery store to shop. When I came back every single one of them had left, none were killed, and they went elsewhere. View Entire Thread

We put Borax in the cracks about the kitchen to feed the ants. They carry it back to their nests, they cannot digest it and they die. We seem to go for 1 to 1 1/2 years without being bothered by them now.
