Serious Ant Problem, Need Help Fast?

My house is INFESTED with ants and I can't get rid of them. I can't call the exterminator because im allergic to the stuff they use, but ive tried so many things like traps, some type of spray, and others. The ants are getting into my pantry and all my food. I hate coming into my house now so I would really appreciate a way to get rid of these pests.
