Vector Control conducts an Adult Mosquito Control program responding to residential areas where high adult mosquito populations exist or have tested positive for West Nile Virus. Sign up for notification of future spray events.
The control program uses an Ultra-Low Volume (ULV) spray which disperses fine droplets into the air. Adult mosquito control is the last step of our Integrated Pest Management (IPM) Plan.
DeltaGuard is registered and approved for to use in and around food crops, livestock, commercial, and residential areas.
Common sense precautions may be used to reuse exposure when applications are scheduled:
When possible, don't walk through fog cloud and stay indoors during applications
Refresh pet watering bowls
Wash toys which may be used by small children
Rinse fruits and vegetables before consumption

Spraying is scheduled evenings 8-11 p.m.
Spraying does not begin until sunset, since adult mosquitoes are most active at that time.
Ideally, you may wish to avoid being outside at the time your area is being sprayed. The nozzle on the truck is angled upward and the material droplet sizes are intended for the material to rise and travel in the slight breeze. Generally, the material travels with the direction of the breeze. The truck operator will discontinue spraying within 50 feet of a passerby when possible.
Truck mounted Ultra Low Volume Sprayer is used to distribute an adult mosquito control spray product (PDF). The product is designed to provide quick, effective control of adult mosquito populations. The application material has a very low toxicity profile to mammals and will have negligible impact to non-target insects and the environment.
