Which of the following is a recommended step to reduce exposure to mosquitoes?

• A. Remove mosquito breeding sites around the home.
• B. Keep screens on doors and windows in good repair.
• C. Avoid outdoor activity when and where mosquitoes are most active.
• D. Wear loose fitting, light colored, long sleeve shirts and pants, hats and gloves when outdoors and contact with mosquitoes is expected.

Answer: (B)

Blocking entry with intact screens is a reliable, passive barrier that reduces mosquito exposure by preventing mosquitoes from entering living spaces. When doors and windows have screens in good repair, indoor areas stay protected without requiring constant action, so people aren’t exposed to bites while indoors or when entering and leaving the home. This approach works continuously, complementing other measures like eliminating standing water and using repellents. While removing breeding sites lowers overall mosquito numbers and wearing protective clothing can reduce skin exposure, screens provide a steady line of defense that works regardless of time of day or personal habits. To keep this protection, regularly check screens for holes or tears and ensure doors and windows seal properly.
