Got Mosquitoes? Here’s Where Williams County Crews Will Be Fogging Tonight
The battle continues against those pesky mosquitoes in Williams County.
Our local vector control district is planning another round of mosquito control Monday evening, August 10, as crews work to help keep mosquitoes under control in several communities or areas close to Williston.
Weather and conditions permitting, the Williams County Vector Control District, or WCVCD, will conduct ground adulticide treatments near sunset using truck-mounted Ultra Low Volume, or ULV, fogging equipment.


Where Will Fogging Take Place?
The mosquito control treatment is scheduled for several areas Monday evening, including:
- The City of Grenora
- The City of Ray
- Trenton
- Spring Lake Park
The timing of the fogging is dependent on weather and other conditions. Residents in those areas may see Vector Control trucks moving through neighborhoods and other areas as crews conduct the treatment.
WCVCD will be using DeltaGard, with the active ingredient Deltamethrin. The product is approved for use in residential areas.
Residents are reminded to stay at least 300 feet away from Vector Control trucks while fogging operations are taking place.
For those who want to see exactly where treatment is planned, a spray block map is available through the Williams County Vector Control District.

A Few Simple Ways to Avoid Mosquito Bites
Even with mosquito control efforts underway, it's still a good idea to protect yourself when you're outside, particularly around dusk and dawn when mosquitoes tend to be more active.
WCVCD recommends wearing long-sleeved, tight-knit shirts and long pants when spending time outdoors. You can also limit your time outside between dusk and dawn and use an insect repellent such as DEET, picaridin, or oil of lemon eucalyptus.
And don't forget to take a quick look around your own property.
Mosquitoes don't need much water to make themselves at home. Dumping out standing water from buckets, flowerpots, toys, birdbaths, and other containers can help reduce places where mosquitoes can breed.
A little prevention can go a long way.
So, if you're in Grenora, Ray, Trenton, or around Spring Lake Park Monday evening, keep an eye out for the Vector Control trucks and give them plenty of room to work.
After all, there's nothing quite like enjoying a North Dakota summer evening without constantly swatting at mosquitoes.
