I am allergic/chemically sensitive to a almost all bug sprays. I had a friend tell me this tip and have used it ever since.
Fill a used squirt bottle (mustard or ketchup bottles, cleaned and washed work really good) with the hottest strongest ground cayenne you can find. Find every hole you see a ant come thru and fill with the cayenne. Seems to work for me.
