This report presents a statewide assessment of pesticides used in California's school system. Of the 46 school districts responding to the statewide survey, 40 claimed using one or more of 27 particularly hazardous pesticides that can cause cancer, affect the reproductive system, mimic the endocrine system, or act as nerve toxins. Forty-three school districts reported routinely using pesticides. The report suggests that not only have California school districts not embraced opportunities for using least-toxic methods to combat pests, but that the state also has no law requiring notification of parents or teachers before applying pesticides in schools. The report recommends: that state policymakers eliminate the use of pesticides that cause cancer; that school managers take the initiative from state agencies to implement reforms; and that teachers, parents, and students request information about pesticides used in and around schools and participate in school pest management decision- making to ensure that least-toxic pest management is practiced. Appendices provide survey methodology, the survey response information by school district, a list of active ingredients found in surveyed schools, a list of resources for further information, and descriptions of the top five pesticides used by the surveyed schools.
