Mosquitoes Test Positive for West Nile Virus

Mosquitoes Test Positive for West Nile Virus

Mosquitoes from a single trap location in the zone east of Grand Junction have tested positive for West Nile virus.

The Grand River Mosquito Control District collected the mosquitoes on August 26, 2021. The types of mosquitoes that tested positive were identified as Culex species, which can transmit West Nile virus to people.

This is the first confirmed West Nile activity in mosquitoes in Mesa County this year. This is the time of year when activity typically peaks, so it’s critical for residents to take precautions. These include:

  • Use an EPA-approved insect repellent effective against mosquitoes. Look for one that contains DEET, Picaridin, IR3535, 2-undecanone, or oil of lemon eucalyptus,
  • Dress in long sleeves and pants when in areas where mosquitoes are active,
  • Avoid being outdoors at dusk and dawn; this is when mosquitoes are most active,
  • Drain and remove sources of standing water on your property.
