Don’t bet on cold winter temperatures to kill off mosquitoes this year. The eggs laid by strains that inhabit the Mid-Columbia are hardy enough to survive the current round of cold temperatures
A prolonged freeze should mean fewer mosquitoes this summer, right?
Wrong, said Amanda Beehler, manager of the Benton County Mosquito Control District.
“We have dormant mosquito eggs out there waiting to hatch and become spring mosquitoes,” she explained.
Tropical mosquito varieties, such as the ones carrying the dreaded Zika virus, perish in cold temperatures. Unfortunately, the strains inhabiting the Mid-Columbia are made of sterner stuff.
“The kind of mosquitoes we have are fine with low temperatures. They’re going to tough it out,” she said.
It is too early to predict what 2017 will bring in terms of mosquitoes. More than a painful nuisance, local mosquitoes spread the potentially deadly West Nile Virus and other diseases.
