Standing water is a breeding ground for summer's most familiar pest.
Mosquito spraying is underway in Williston to beat the pest.
Earlier today, a U.S. Air Force plane sprayed the Little Muddy River near Williston.
Plans were put in place to Larvicide the area earlier this week, but were canceled due to inclement weather.
Larviciding is spraying mosquitoes before they emerge into adults.
The type of spray used is a bacterial product that is environmentally safe and only affects the mosquitoes.
Vector Control Director, Francis Bosch, says this year's spraying of the mosquitoes is especially important, given Williston's population increase.
(Francis Bosch, Vector Control Director at Williston Vector Control District)"Bigger populations and there are a lot of changes in the land use out here. There is going to be more insect-human interactions, so it's more important than ever to keep the pest populations down."
Williston has been spraying the area since 2009.
