Colonies raised off the ground
Once ants are established in a colony, they are difficult to control. To minimize ant problems maintain strong colonies and keep bottom boards raised off the ground. Also, remove brush, rotten wood, grass, and weeds from around the colonies. A fuel oil barrier applied to the soil under the colonies may be helpful. Single colonies can be placed on stands with oil or sticky barriers. Ant problem may also be reduced by allowing the bees access to the space between the inner and outer covers.
