11. IPM Integrated Pest Management Integrated Pest Management “…the coordinated use of pest and environmental information with available pest control methods to prevent unacceptable levels of pest damage by the most economical means and with the least possible hazard to people, property, and the environment.” - EPA “…the coordinated use of pest and environmental information with available pest control methods to prevent unacceptable levels of pest damage by the most economical means and with the least possible hazard to people, property, and the environment.” - EPA AKA: common sense AKA: common sense

12. Steps of IPM 1. INSPECT AND INVESTIGATE 2. IDENTIFY AND LEARN 3. MONITOR 4. IS IT WORTH IT? 5. CHOOSE CONTROL METHODS 6. EVALUATE
