This website has a lot of suggestions for getting rid of ants. Some are indoors and some are outdoors. In addition to all of these ideas, diatomacous earth is a natural bug killer that has been in use for a long time. Wishing you the best.
Hi Dale: This is what I used for my ant problem, it may work for you, too.
Make a mix of 1/2 baking soda and 1/2 powdered sugar. Mix well and put around the spots they are in your garden, or inside your home, it's harmless to people and pets. For outside use, you can put it in a bottle, like a pill bottle or something like that. Cut a hole on the edge of the cap, and lay the bottle on it's side so the ants can come in and get the mix. This way, it stays dry if it should rain. They will take it back to the nest and it should kill them. I'd keep it out there all season if you can. The mix makes a gas and the ants can't pass gas, so it kills them. Anything else that eats it will just taste the baking soda and say "Yuck" and walk off. It won't hurt anything that can pass gas, so it's completely safe. It helps to know what type of ant you are trying to get rid of, too.

My all-time best, favorite, and always effective ant treatment is to mix 50/50 Borax laundry soap (or boric acid) with table sugar. This kills ants in 3 ways: they die eating it, it eats through their exoskeleton and they die, they feed their dead to the nursery which will finally kill off the nest.
