Mosquito season now here

Posted: Updated:

RICHLAND, Wash--  Hidden deep behind this thick grass are baby mosquitoes.  They grow in water and the Benton County Mosquito Control District is quick to find them.

"We're looking for larva and/or pupa," says Aaron White with the district.  "If we find one, then we take a sample of it and try and find enough to send off and see a disease study on them, find out if we have West Nile in the area."

It's near the start of the new mosquito season-- one that could be headed for a little re-shaping at the hands of the Department of Ecology.   Ecology is concerned about pesticides getting into the water, and that's why they're working on a new permit.  One question waiting to be answered is whether districts can spray for just diseased mosquitoes, or if they're allowed to spray for nuisance ones, too. 

"For the adulticiding portion of our control program, we are using a kind of broad spectrum insecticide, but the key point is we use it in incredibly small quantities," explains Kevin Shoemaker with the district.

Whatever changes to mosquito control, we should know in about a month.  Workers at the Benton County Mosquito Control District say they fully expect changes are in store.
