Electric Mosquito Control Equipment in Practice: Field Data, Benefits, and Performance

When it comes to mosquito control equipment, the shift to electric is no longer theoretical — it’s happening in the field right now. Programs across the country are making the transition, and what we’re seeing is encouraging: electric mosquito control is practical, cost-conscious, and easier to fit into day-to-day operations than many people expect.

 

So what does that actually look like on the ground? Here’s a closer look at what real field data is telling us about electric vehicles, sprayers, and other mosquito control equipment — straight from our operations team in the Chicagoland area.

 

At Clarke, this kind of progress reflects a broader commitment to stewardship. Through EarthRight, we have continued to advance lower-impact approaches to mosquito control that support public health while reducing environmental impact. That includes pairing naturally derived products with application methods like bicycles, hybrid vehicles, and electric sprayers to help programs take meaningful steps toward more sustainable operations.

Across public health mosquito control programs, the move toward electrification is also underway. One recent study found that 88.6% of mosquito abatement districts are using a mix of gas and electric ULV sprayers, while only a small share still relies on gas-powered equipment. Every district surveyed also said they plan to move toward electric sprayers in the future.

The motivation is not just environmental. Programs are making the shift for a mix of practical reasons, including:

• Environmental sustainability
• Reduced fuel costs
• Quieter operation
• Improved operator comfort and safety
• Positive public perception

For many programs, the shift comes down to everyday impact: smoother operations, lower fuel use, quieter equipment, and a better experience for both operators and the communities they serve. 

What Electric Fleet Performance Looks Like in the Field

Electric vehicles are already supporting a wide range of mosquito control work, from ULV night spray routes to inspections and trap maintenance. In other words, they’re no longer being evaluated from the sidelines, but a part of real-world operations. 

For example, Clarke’s field-tested Chevrolet EV trucks have shown:

• Up to 393 miles of range, supporting a full day of operations.
• Reliable performance across multiple route types
• Flexibility to serve as both spray vehicles and transport for field crews.

One of the biggest questions people tend to ask is about range. In fact, there’s a term for it called “range-anxiety”

But, real-world data shows that concern is smaller than most expect. In field use, Clarke’s vehicles were returning with 35-63% battery remaining, even after traveling about 150 to 215 miles in a day throughout our larger operational area. 

Smaller electric vehicles are proving useful, too. Models like the Chevy Bolt can manage daily inspection and surveillance work while offering quieter operation and lower overall ownership costs, thanks to reduced fuel and maintenance needs. 

Electric ULV Sprayers Bring Immediate Advantages 

Electric ULV sprayers are another area where the benefits become clear quickly once they are in use. 

Compared with gas-powered units, electric sprayers are:

• About 30 decibels quieter than gas-powered units – a meaningful difference when spraying residential neighborhoods after sunset
• Free of engine exhaust at the point of application
• Similar to maintain, with fewer moving parts

Taken together, these advantages can help programs reduce fuel use, simplify maintenance, and improve efficiency over the life of the equipment.

Features like swappable batteries and compatibility with Clarke’s SmartFlow II GPS-guided flow control system also make it easier to keep operations running smoothly without giving up important tracking and efficiency tools.

What It Takes to Make the Shift from Gas to Electric Vehicles

                                    

Of course, switching to electric equipment does take planning, especially when it comes to charging. Most programs rely on Level 2 overnight charging, which helps ensure vehicles are ready for a full day in the field. 

There are also a few operational decisions to think through, such as:

• Hiring or training EV-certified mechanics
• Evaluating buying vs. leasing for flexibility
• Selecting the right vehicle types for operational needs

There are still some gaps in the current vehicle market, especially when it comes to mid-size electric trucks, but that has not stopped organizations from finding practical ways to make EVs work right now.

Electric Backpack Sprayers Are Proving Their Value

It’s not just vehicles that are changing. Backpack sprayers are evolving too, and field evaluations show that electric models are genuinely competitive with gas-powered options in real-world situations. 

In controlled comparisons between electric (Birchmeier) and gas-powered (Stihl) backpacks:

• Electric units delivered more consistent flow rates, reducing risk of over- or under-application.
• Both systems achieved near-complete efficacy at close range.
• Differences in canopy penetration were minimal in practical conditions.

Electric backpacks also brought some clear day-to-day benefits, including more consistent application, better operator comfort, and the potential to reduce pesticide use and customer complaints.

• Reduced variability in application
• Improved operator comfort
• Potential for lower pesticide use and fewer customer complaints.

That said, gas-powered units still showed a few advantages, like wider swath width and slightly stronger canopy penetration. So, electric is a strong performer for most applications, and the right choice will depend on how each program uses them. 

Most Programs Are Taking a Gradual Approach

 

For most mosquito control programs, the shift to electric is not happening all at once, and that is okay.

Many organizations are finding success with a phased approach, which may include:

• Starting with electric ULV sprayers
• Adding electric or hybrid fleet vehicles
• Gradually expanding charging infrastructure
• Scaling adoption over multiple seasons

Even partial adoption can make a meaningful difference. In one example, electric and hybrid vehicles accounted for about 10% of operational miles, while additional electric equipment supported other parts of the workflow.

So, What’s the Takeaway?

Electric mosquito control equipment is no longer experimental. It is already being used in real operations, and the results are in. 

Based on what field data is showing so far, a few things are becoming clear:

• Performance is comparable to traditional equipment.
• Costs are lower over time.
• Community and regulatory expectations are shifting toward cleaner, quieter solutions.

The question isn’t whether electrification is coming to mosquito control, it’s already here. 

If your program is exploring electric equipment, Clarke can help you evaluate where it fits, what it takes to get started, and how to build an approach that works in the real world.
