Which is best chemical control of filth flies

• A. Sanitation
• B. IPM
• C. Bait
• D. Screens

Answer: (B)

Integrated Pest Management (IPM) is the best way to approach filth fly control because it treats control as a system, not a single tool. IPM combines sanitation to remove breeding sites, exclusion to keep flies out (like screens and sealing), regular monitoring to know when action is needed, and targeted chemical controls only when necessary. This approach minimizes chemical use, reduces risks to people and the environment, and helps prevent resistance by not over-relying on one product or method. While sanitation, baiting, and screens are important parts of a program, IPM coordinates them into an effective, sustainable plan that uses chemicals judiciously within a broader strategy.
