A great natural remedy to keeping ants away from your home or to rid your home of them, try using corn meal around the edges of the kitchen. You can use your regular cooking corn meal for the best results. If you have them in your kitchen then I would recommend placing corn meal at the base of all your cabinets along the floor near the kick plate area. Also you can try using the Diatomaceous earth all the way around the perimeter of your house. This will create a natural barrier for the ants and keep them out of your home. You should be able to find Diatomaceous Earth at your local garden center or if you can not locate it there, they might have some in the pool supply area. This is also used inside some types of pool filters.
