The Healthy Schools Act of 2000 was signed into law September 2000 and requires that all schools provide parents or guardians of students with annual written notification of expected pesticide use on school sites when children are not present.  Notification will identify the active ingredient or ingredients in each pesticide product and will include the Internet address for further information on pesticides and their alternatives.  We will send out annual notifications in September of each year.
