Indoors, if the little buggers are coming in- find the spot they are entering and plug it with any brand of white mint toothpaste! The detergent in it upsets their tummies, they hate mint, and the abrasive does a job on their jaws! They absolutely will NOT chew through it!

Outdoors, folks used to plant pennyroyal, a member of the mint family by their doors to discourage ants from entering. Any large nursery should have it with the herbs. Lastly, gather up all those cigarette butts and make some nasty "tea". Pour it down the ant hole. Sends them into convulsions!- Granny:hippy:
