Integrated Pest Management

Principles of IPM

Integrated Pest Management (IPM) is a holistic and environmentally sustainable approach to pest control. It employs a combination of preventative measures, cultural controls, biological controls, and chemical controls as a last resort. The goal of IPM is to maintain pest populations at acceptable levels while minimizing the impact on human health and the environment.
