A method and composition of controlling and eliminating insects is provided. The method and composition of eliminating sophisticated chemical communication systems between insects is enhanced where insects live in functional groups, such as swarms, nests, colonies, hives, breeding pools, mounds, mating areas and other interdependent social groups. An odor neutralizer is applied directly into or in close proximity of the social group activity. The odor neutralizer chemically modifies and neutralizes the sophisticated communication chemicals known as pheromones which control sensory recognition, stimulate activity responses and facilitates communication abilities which the insects use to give commands and function as an interdependent group. The odor neutralizer is a blend of natural plant oil products. The odor neutralizer is chemically reactive with the insect pheromones, and neutralizes or modifies the pheromone. These compositions or compounds are biodegradable, nontoxic, non hazardous to the environment, adults, children, and pets. The pheromone odor neutralizer can be used in many forms including an oil-based or water-based spray, a vapor, a gel, and a cream or deposited as a solid using an absorbent carrier. The odor neutralizer is applied into the openings and the area surrounding the insect nests, so that the vapor can penetrate the proximity of the nest. Direct insect contact with the liquid or ingestion by the insect, is not necessary. The vapor creates an atmosphere that disrupts the ability of the insects to function as a group. Within 48-72 hours, the ability to communicate is disrupted, the pheromone based communications are neutralized or unrecognizable, and the social unit of insects no longer functions, thereby eliminating the nests.
