A pheromone trap is a type of insect trap that uses pheromones to lure insects. Sex pheromones and aggregating pheromones are the most common types used. A pheromone-impregnated lure is encased in a conventional trap such as a bottle trap, Delta trap, water-pan trap, or funnel trap. Pheromone traps are used both to count insect populations by sampling, and to trap pests such as clothes moths to destroy them.

The Boll Weevil Eradication Program is a program sponsored by the United States Department of Agriculture (USDA) which has sought to eradicate the boll weevil in the cotton-growing areas of the United States. It's one of the world's most successful implementations of integrated pest management. The program has enabled cotton farmers to reduce their use of pesticides by between 40-100%, and increase their yields by at least 10%, since its inception in the 1970s. By the autumn of 2009, eradication was finished in all US cotton regions with the exception of less than one million acres still under treatment in Texas.
