Mosquitoes

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.

General prevention tips

Eliminate breeding sites

  • Change water in pet dishes and bird baths at least once a week.
  • Aerate ornamental ponds or stock them with fish.
  • Keep grass mowed.
  • Keep gutters cleaned.

Avoid mosquito bites

  • Be aware that mosquitos will be present in woodlands, near natural and man-made ponds and lakes, and near unaerated basins of water. Take precautions.
  • 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.

  • Ensure window screens and door screens are present and in good repair.
