What is IPM?What is IPM?IPM = A decision-making strategy that IPM = A decision-making strategy that focuses on long-term focuses on long-term preventionprevention of pests of pests
Inspect for pest and correctly identify; monitor for pest activity; keep records!
Eliminate sources of food, water, and shelter—use exclusion methods (maintenance) and sanitation.
Use non-chemical practices and chemical controls that pose the least possible hazard (low toxicity + minimal exposure).
Routine perimeter spraying is not IPM!

Take-home messagesTake-home messagesHSA―Right-to-know law; IPM voluntary
Pesticides―not all equal; some are necessary to use
Perimeter & broadcast sprays bad
Use less toxic pesticides & minimize exposure
IPM cleaner, better-maintained schools
Several barriers prevent instant adoption of IPM, but IPM is achievable
IPM is a sustainable way to solve pest problems
