Beneficial insects and mites

Natural enemies are beneficial organisms that can enhance pest control, often providing suppression of many indirect pests, such as mites and leafhoppers. The best ways to conserve beneficial insects are to use caution when selecting pesticides and timing applications, and to restrict use of predator-toxic products, particularly later in the season.
