Most ants are chemically sensitive, and some are especially sensitive. The Odorous House Ant for example will shatter their one colony into multiple sub-colonies when they are treated with certain materials. Each colony has multiple queens and they will continue dividing their forces as long as they think they are in danger. The materials available to you over-the-counter at your local store are strong repellents. These products can make any infestation worse. Appropriate materials, equipment, and knowledge is key to resolving any pest infestations.
