Which statement best reflects the IPM principle regarding control methods?

• A. IPM uses the least-toxic control method first
• B. IPM relies solely on chemical controls
• C. IPM ignores monitoring
• D. IPM uses no controls

Answer: (A)

IPM aims to manage pests with the least risk to people, pets, non-target organisms, and the environment by using a range of tactics in a thoughtful order. The best statement captures that mindset: start with the least hazardous control method and only escalate if monitoring shows pest levels require it. In practice, this means prioritizing prevention, sanitation, exclusion, and non-chemical or physical/biological methods first, and applying the most targeted, lowest-risk chemical options only as a last resort when pest thresholds are exceeded and after careful assessment.

This approach contrasts with relying exclusively on chemicals, ignoring monitoring, or eliminating the use of any controls altogether.
