What is an example of a mechanical control method for mosquitoes?

• A. Fogging with pesticides
• B. Installation of window screens
• C. Applying larvicides to water
• D. Using chemical repellents

Answer: (B)

The correct answer is the installation of window screens, which serves as a mechanical control method for mosquitoes. Mechanical control methods involve the physical alteration of the environment to prevent pests from entering or breeding. By installing window screens, you effectively create a barrier that keeps mosquitoes outside, reducing indoor populations and preventing bites. This method does not rely on chemicals or biological agents, making it a straightforward approach to pest management. Fogging with pesticides, applying larvicides to water, and using chemical repellents are all examples of chemical methods of control. They involve the use of substances designed to kill or repel mosquitoes rather than altering their environment or physical access. Thus, mechanical control, like window screens, stands out as an effective, non-chemical solution.
