How do you get rid of ants near a honey bee hive?

We are second year beekeepers and have had this problem this year also. The books I have read tell me to buy a big jar of ground cinnamon from a restaraunt supply store and sprinkle it liberally near the base of the hive and open up the telescoping cover and sprinkle it on the top. The bees don't mind it and the ants hate it! Good luck!
