For long-term rodent control, which combination of methods is recommended?

• A. Cultural and mechanical
• B. Mechanical and physical
• C. Chemical and sanitation
• D. Biological and mechanical

Answer: (A)

Long-term rodent control relies on an integrated approach that combines habitat modification with active removal. By addressing what attracts rodents and how they gain entry (cultural methods), you make the environment less inviting and harder to access, such as through proper sanitation, secure food storage, removing clutter and potential harborage, and sealing entry points. Pairing that with mechanical methods—the use of traps and other devices to capture or kill rodents—directly reduces the existing population. Together, these strategies lower both the number of rodents and the chances of reinfestation, providing a more durable solution than relying on chemicals alone, which can be temporary and pose health and safety concerns. Biological options are often impractical for sustained control in many settings, and relying solely on mechanical methods without reducing attractants and entry also misses the ongoing prevention that keeps rodent pressure low.
