Records should be kept for at least how many years?

• A. At least 1 year
• B. At least 2 years
• C. At least 5 years
• D. At least 10 years

Answer: (B)

Keeping records serves as a factual trail that shows pesticide applications were made according to label directions and that the right details are documented for accountability and review. In Wisconsin, you’re required to retain pesticide application records for at least two years. That two-year window gives regulators and whoever handles follow-up enough time to review past treatments, verify compliance, and monitor any issues such as environmental impacts or pest resistance.

Shorter periods, like one year, wouldn’t provide a complete window for audits or investigations, while longer periods (five or ten years) aren’t required unless another rule applies. Therefore, two years is the correct requirement.
