As a mother, I understand the importance of a healthy school environment in which to educate our children. As an environmentalist, I understand the need to eliminate the unnecessary use of any toxic chemical. The use of integrated pest management (IPM) in and around school buildings addresses both of these concerns while prepar- ing our children to become tomorrow’s environmental stewards. This booklet will provide you with a general understanding of IPM principles, so that you may make an informed decision about pest control in your neighborhood schools. As EPA’s Administrator, I encourage all schools to reduce the use of pesticides by adopting integrated pest management. Carol Browner Administrator Environmental Protection Agency

Step 1 Developing an Official Policy Statement for School Pest Management A policy statement for school pest education and involvement of students, management should state the intent of staff, and pest manager. The model policy the school administration to implement assessment in figure 1 is provided as an IPM program. It should briefly provide an example and may be modified in any guidance on what specifically is way by schools to reflect site-specific Figure 1 expected--the incorporation of existing needs or intent.
