"Hot Temperatures and Sierra Snow Trigger Surge in 'Snowmelt Mosquitos' in Placer County"
The recent spike in hot temperatures and significant Sierra snow has led to the emergence of "snowmelt mosquitoes" in some areas of the Sierra. The mosquitoes were previously under the snow but have now hatched due to the faster snowmelt caused by the heat. The Placer Mosquito and Vector Control District is monitoring the situation to determine if the winter's heavy snow and rain have contributed to higher mosquito numbers. The activity of the mosquitoes depends on elevation, location, and current snowmelt conditions. While the mosquitoes found in higher elevations do not carry the West Nile virus, they are aggressive and like to bite, so wearing repellent is advised.
