Borax works for killing ants. I found ants in the kitchen, didn't know where they were from. Read online and tried putting borax along the kitchen counter, the edge of the sink etc. Then I went to Seattle with my doggy. Couple days later we got home, cleaned up the borax with a vacuum cleaner. I haven't seen any ants since. It works wonder :)

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.

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.
