Current metro mosquito population triple the 10-year average

The Metropolitan Mosquito Control District says a cold, rainy spring has led to a boom in the mosquito population this summer, Minnesota Public Radio reports.

The district said based on a find in one of their mosquito traps this week, the population is three-times as high as the 10-year average. There are 134 traps set in all in the metro area.

According to MPR, the explosion in the mosquito population began in mid-June. The "cattail mosquito" is currently in the air in the Twin Cities, after the season peaked July 4. The cattail mosquito is described as a particularly aggressive strain that hatches in cattail swamps.

MPR says there are 51 mosquito species in the state, and the district focuses on the ones that bite people, and the ones that carry disease.

Mosquitoes are carriers of the West Nile Virus, which was discovered in a find by the district in the south metro earlier this month. As of July 3, no Minnesotans have been diagnosed with having the virus.

The Argus Leader in South Dakota said a child had become the first person diagnosed with the disease in the state.

According to, Chippewa County Wis., Friday became the fourth county in the state to report that a bird has been found to be infected with West Nile -- a sign that the virus is in the present in the area.
