The deadly mosquito

The mosquito is the most deadly animal in the world. Every year mosquitoes transmit hundreds of millions of infections and kill an estimated 725,000 people.

Mosquitoes are most active in the United States from June through September. However, they will emerge as soon as the temperature is consistently above 55⁰ F. In Indiana, there are approximately 55 species of mosquitos that have been identified.

  • Wear long sleeves, long pants, and socks outdoors.
  • Use repellents that contain lemon eucalyptus oil, DEET, picaridin, or IR3535. Use these products as directed by the manufacturer.
