Learn what you can expect from any of the parasites or predators you purchase. After allowing enough time for beneficials to act, decide if a pesticide is still needed. Choose the lowest rate of application. During the off season, decide if cultural practices, such as planting dates, spacing, or sanitation could help you avoid the pest problem next year. Design habitat for beneficials and continue adjustments until the plan is successful.
Biological control takes motivation, patience, and knowledge, but the rewards can be great.
