Pesticide Label Reading
Understanding all sections of pesticide labels - target pests, application rates, timing, precautions, PPE, re-entry intervals, and legal requirements.
Detailed Overview
Labels are legal documents that must be followed exactly. Label sections: (1) Product name and EPA registration number: identifies specific product and approval. (2) Signal word: DANGER (highly toxic), WARNING (moderately toxic), CAUTION (slightly toxic). Indicates acute toxicity. (3) Active ingredient: chemical name and percent concentration. (4) Target pests: specifies which pests product labeled to control - using on unlisted pest is violation. (5) Application sites: where product can be legally applied - using on unlisted sites prohibited. (6) Directions for use: how to mix and apply. Mandatory - must follow exactly. (7) Application rates: minimum and maximum amounts allowed. Cannot exceed maximum. (8) Timing and frequency: when and how often can apply. (9) PPE requirements: what protective equipment applicator must wear. (10) Environmental hazards: warnings about fish toxicity, groundwater concerns, bee protection. (11) Re-entry interval (REI): how long people must stay out of treated area. (12) Storage and disposal: how to handle product safely. Reading labels: read entirely before first use, refer to label when questions arise, keep labels accessible, update when revised. Legal principle: label is law - any use not specifically permitted is prohibited.
When to Use
Read label completely before using any product for first time. Reference label when uncertain about permitted uses. Keep current labels accessible. Follow label directions exactly.

Integrated Pest Management (IPM)
A prevention-based pest management method that provides long-lasting pest control, improves building conditions, and is less harmful to residents and pets than traditional pest control.
Pest Triangle
The four essential requirements pests need to survive: food, water, shelter, and ways to get around. Eliminating any of these makes an environment inhospitable to pests.
Threshold Levels
The point at which pest populations or damage reaches a level that requires action. IPM uses threshold levels to determine when treatment is necessary rather than treating on a schedule.
