What is Integrated Pest Management? 

IPM is managing pests by managing their environment. Integration means using a variety of tools, including pesticides. Sometimes the safest and most effective tool is a pesticide. But with IPM, pesticide use is always a well-reasoned decision. You should not just grab a spray can. There are three simple steps to an effective IPM program.

Identify and monitor pests

IPM begins by identifying the pests in and around school property and monitoring the level of infestation. Accurate pest identification is critical. Each pest has a life cycle and certain environmental needs. Proper identification and monitoring makes it easier to select the most appropriate, cost-effective control available.

Determine the action threshold

The "action threshold" is the level of pest infestation and activity that can be tolerated. The threshold for each pest is determined by the severity of the injury caused by the pest, site characteristics, health concerns related to the pest and site user needs.

Take action to prevent or control the pest

IPM encourages using the tool or combination of tools that will create the safest and most effective control program. Some of the most commonly used tools include sanitation, structural repair and maintenance; watering and mowing practices; pest-resistant plant varieties; and judicious use of pesticides.

*Pest definition: Any living organism that by the situation or size of its population adversely interferes with the health, environmental, functional or economic goals of humans.
