August 2026 District Update

The Mosquito Season Is Winding Down… But We’re Not Quite Done Yet

It is hard to believe we are already approaching the end of another mosquito season. As we head toward September, the Four Rivers Vector Control District is beginning to transition from full-time seasonal operations to more limited, part-time and on-call operations.

That does not mean the mosquitoes received the memo.

Warm weather can continue producing mosquito activity well into the fall, so if mosquitoes become a problem in your neighborhood, please continue reporting them through our Mosquito Hotline or website. Your reports help us determine where crews need to inspect and whether additional treatments are necessary.

Did You Notice a Difference This Year?

We certainly hope so.

One of our primary goals for 2026 was to make mosquito control more proactive, responsive, and strategic. Staff spent the season locating and treating mosquito sources, responding to service requests, monitoring populations, larviciding breeding areas, and fogging where mosquito numbers justified treatment.

Overall, mosquito populations have remained significantly lower this season, and we believe the combination of environmental conditions and aggressive preventative mosquito control played an important role.

Most importantly, staff worked hard to ensure that every service request was reviewed and addressed.

If you called us or submitted a report online, we wanted that information to make its way to the people actually working in the field—not disappear into a black hole somewhere.

Please keep those reports coming.

About That Loud Fogger…

Residents may have noticed that our newer fogging equipment is considerably louder than the older electric foggers.

Actually, "may have noticed" is probably an understatement.

You heard it.

The newer equipment provides more reliable and efficient applications and allows us to better control application rates as vehicle speeds change. Despite the additional noise, we received very few complaints about it this season, and we appreciate everyone's understanding.

Sometimes effective mosquito control isn't particularly quiet.

Thank You to Our Seasonal Staff

A tremendous amount of work goes into mosquito control that most residents never see.

We would especially like to thank all of our seasonal employees who worked alongside Edward and the District team this year. From nighttime fogging to daytime mosquito surveillance, larviciding, mapping, equipment work, and searching through some less-than-pleasant mosquito habitat, their work made this season possible.

And we're already thinking about next year.

Looking for a Summer Job?

If you—or someone in your family or circle of friends—is looking for seasonal employment next summer, we are interested in hearing from you.

We need people willing to work as:

• Nighttime fogging operators
• Daytime mosquito and larvae hunters
• Seasonal mosquito control technicians

If spending your summer hunting mosquitoes sounds strangely appealing, you might just be our kind of person.

Contact the District and let us know you're interested.

We Still Need a Board Member

The District continues to have an opening on its Board of Trustees.

We're looking for a community member who wants to help guide the future of the District and contribute to improving mosquito and vector control services.

Board service generally requires one regular meeting per month, along with occasional committee meetings, budget meetings, or training.

Our Board members have also been investing time in their own education. This month, the Board participated in Board training, and next month members will complete additional ethics training.

If you have an interest in public service, responsible use of taxpayer dollars, mosquito control, or simply making your community better, please contact us about serving on the Board.

A More Balanced Budget & Planning for the Future

The Board has adopted a more balanced budget as part of its continuing effort to strengthen the District's finances and long-term operations.

With the immediate financial and operational priorities being addressed, we can now begin focusing more attention on the future.

One major priority will be upgrading and replacing aging equipment and vehicles over the next several years. Reliable mosquito control requires reliable equipment, and our goal is to make these improvements responsibly rather than waiting until something breaks at the worst possible time—which, as equipment tends to do, is usually exactly when you need it most.

Fall, Winter & Spring Work Along the River

Mosquito control doesn't completely stop when summer ends.

During the fall, winter, and spring, we would like to improve access to known mosquito-producing areas, particularly along the river.

If you own or manage property with areas that regularly hold standing water in brush, trees, depressions, or other difficult-to-access locations, please contact us.

We would like to work with property owners to identify ways to improve access for mosquito control crews. Better access means we can treat mosquito larvae earlier and more efficiently—before those larvae become thousands of flying adults.

Preventing mosquitoes is almost always easier than chasing them afterward.

We're Still Planning an Open House

We haven't forgotten!

The District still hopes to hold an Open House this fall so residents can meet staff, learn how mosquito control works, see some of our equipment, and ask questions.

The biggest challenge so far has simply been finding a day that works with everyone's schedules.

We will share more information once a date is selected.

Want to Know When We're Fogging?

Residents can sign up through our website to receive text notifications when fogging is scheduled in their neighborhood.

If you would like notifications, please submit a notification request through the website.

A Reminder About the No-Spray List

Residents who request to be placed on the District's No-Spray List must renew their request each year.

If you are currently on the list and would like to remain on it for 2027, please remember to submit a new request beginning in January.

Annual renewal helps us keep the list accurate and ensures our crews are working with current information.

Heading Into September

As mosquito activity declines, our staffing and field operations will begin scaling back. However, we will continue responding when conditions require it.

If you're getting bitten, tell us.

Don't assume someone else has already reported the problem. Your mosquito report gives us valuable information about what is happening in your neighborhood and helps us determine whether inspection or treatment is needed.

Thank you to everyone who reported mosquitoes, signed up for notifications, allowed us access to mosquito-producing areas, served on the Board, worked on our seasonal crews, or simply gave us some patience while we made significant changes this year.

We hope residents have noticed the difference.

And if you haven't—or if there is something we could be doing better—we want to hear that too.

Thank you for helping us make the Four Rivers Vector Control District better.
