Evening Control Program

West Nile Truck
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:
    • This product degrades quickly in sunlight, and therefore it has a short residual time in the environment.
    • The active ingredient in this product is similar to that used in dog flea and tick prevention medication.
    • Biomist is registered for and is safe to use in and around food crops, livestock, commercial, and residential areas.
    • Although safe, common sense precautions should be used when applications are scheduled:
      • When possible, don't walk through fog cloud and stay indoors during applications
      • Refresh pet watering bowls
None Scheduled: Mosquito season end September 25, 2015

Spraying is scheduled evenings 7-11 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. If the truck is spraying while you are out, avoid being directly in the spray path. 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.
