Williston Mosquito Spraying Plan For August 31 Through September 3

Just when you thought mosquito season might finally be winding down, the bugs aren't quite ready to give up yet.

The Williams County Vector Control District (WCVCD) will conduct both ground and aerial mosquito treatments this week, weather and conditions permitting. The treatments are being conducted as mosquito populations remain active and West Nile Virus continues to be detected through routine mosquito sampling.

Ground Spraying in Williston

The WCVCD will use truck-mounted ultra-low volume, or ULV, fogging near sunset.

The schedule includes:

Monday, August 31: Williston Spray Blocks 1, 2, 3 and 4
Tuesday, September 1: Williston Spray Block 5

The treatment will use DeltaGard, with the active ingredient deltamethrin, which 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 underway.

Aerial Treatments Are Also Planned

Aerial adulticide treatments are scheduled after sunset from Monday, August 31, through Thursday, September 3, weather permitting.

Those treatments will include the cities of Grenora and Ray, Trenton, western Williston, including Spray Blocks 8, 9 and 10, along with other unincorporated areas between the Highway 85 Bypass and Williston city limits.

Recent rainfall, along with a late-season increase in mosquitoes, has contributed to the need for the additional treatment.

A Few Ways to Avoid the Bite

If you're heading outside around dusk or dawn, WCVCD recommends wearing long sleeves and long pants, limiting outdoor time during peak mosquito activity, and using an appropriate mosquito repellent such as DEET, picaridin, or oil of lemon eucalyptus.

It's also a good idea to check around your property and eliminate standing water whenever possible.

Mosquito season may be nearing its end, but apparently the mosquitoes didn't get the memo.

Feeding the Nation: A Look at North Dakota’s Most Valuable Crops

Farming is the backbone of America—98% of the nation’s 2 million farms are family-run, feeding an average of 166 people each year. Though agriculture makes up just 1% of the U.S. economy, it’s rich in tradition and diversity, with more African American, Hispanic, and Latino farmers than ever before. One in four are new to the field, and many have served in the military.

In 2022, U.S. farm exports hit a record $191 billion. According to Stacker, here’s how North Dakota’s top crops ranked by value—and why the Peace Garden State punches above its weight in feeding the world.
