The Battery-Powered On-Hive Fogger delivers precise, repeatable Hive Health applications directly on single- or double-deep hives. Add the recommended volume, place the unit on the hive, turn on the switch, and achieve consistent coverage with less operator variability.
Precise
Select the recommended dose for the hive configuration and application period.
Repeatable
Use the same setup and treatment process from one hive to the next.
Portable
Move through the yard without extension cords, generators, or access to 110V power.
Built for every apiary
One application system. Multiple ways to use it.
Bring automation to the backyard apiary.
Get a repeatable Hive Health application without relying entirely on manual spray technique.
Create a more efficient yard-to-yard workflow.
Run a single unit or add more foggers as hive count and treatment workload increase.
Run multiple foggers in parallel.
Deploy independently powered units across a yard while crews prepare, move, or refill other units.
Simple, repeatable workflow
Seven steps from setup to the next hive.
Follow the same operating sequence at each colony for a consistent Hive Health application.
01
Connect the battery
Mount a compatible DeWalt 60V battery onto the electrical housing. A 9 Ah battery runs for roughly 25 minutes; a 12 Ah battery runs for roughly 40 minutes.
02
Place the fogger on the hive
Open the top of the hive and position the On-Hive Fogger directly on the open hive frame.
03
Fill the fog generator basin
Remove the lid and add prepared Hive Health to the reservoir until the liquid is above the desired level. Recommended fill range: approximately 1.0–1.8 L.
04
Replace the fogger lid
Secure the chamber lid so the fog is directed down into the hive once the unit is activated.
05
Turn on power
Flip the red toggle switch on the control box. The switch illuminates when the power connection is active.
06
Run the treatment
Once the red switch is on, the fogger begins operating. Let it run until the measured solution has been applied or the liquid level becomes too low.
07
Reset and move to the next hive
Turn off the red switch, remove the fogger, move it to the next hive and repeat Steps 2–7.
Operating check: If the display drops below approximately 290 W, allow the piezo fog generator to cool before continuing.
Designed around the hive
Purpose-built for direct-on-hive application.
The enclosed application chamber, internal airflow system and removable components create an approachable, repeatable treatment process.
Direct hive placement
Sits directly on common Langstroth configurations.
Controlled airflow
Internal fans move application through the chamber and into the hive.
Removable components
Designed for filling, cleaning, and regular maintenance.
Integrated controls
Power switch and display remain visible during operation.
Made for Hive Health
A more repeatable way to apply Hive Health.
The On-Hive Fogger gives beekeepers an automated application option that reduces dependence on manual spray technique and supports a consistent treatment workflow across the season.
Use with live colonies
Designed around Hive Health applications for bees, brood, and queens when used according to current guidance.
Measured dosing
Add the recommended volume for the hive configuration before starting the unit.
Use across the season
Integrate treatments into early-season buildup, mid-season colony support, and fall preparation.
Standardize applications
Use the same equipment, placement, measured dose, and application process across hives and operators.
Not compatible with Hive Wash. The On-Hive Fogger is intended for Hive Health applications in live colonies. Hive Wash is intended for deadouts and equipment without live bees present.
Why automate?
Move from operator-dependent to repeatable.
The difference is not simply how Hive Health is applied. It is how consistently the same workflow can be repeated from hive to hive, operator to operator, and yard to yard.
Manual workflow
Spray application
Coverage varies
Results depend on spray angle, distance and how thoroughly each hive is treated.
Timing is manual
The operator controls the treatment duration at every hive.
Technique changes by user
Training and individual technique can affect consistency across a crew.
Automated workflow
On-hive fogging
Repeatable placement
The fogger sits directly on the hive using the same setup each time.
Controlled application
Once switched on, the fogger runs with less hands-on input while the measured dose determines the application length.
Easier to standardize
Crews can follow one repeatable process across different yards and operators.
Repeatable
Same workflow at every hive
Precise
Measured dose matched to hive type
Trainable
Simpler process across crews
Portable
No cords or generator required
Commercial workflow
Run multiple foggers. Treat multiple hives at once.
Each On-Hive Fogger runs on its own battery, allowing crews to deploy several units simultaneously across a yard. Use the infographic below to explain the repeatable multi-unit workflow at a glance.

Request Commercial PlanningBuilt for the beekeeping season
Carry one application method across the year.
Early-season buildup
Support colony development as brood production and hive activity increase.
Mid-season support
Continue applications during active colony periods according to the seasonal plan.
Fall preparation
Use the higher recommended dosage range when appropriate as colonies prepare for winter.

FAQ
Common questions
Does the On-Hive Fogger require 110V power?
No. This version runs on the DeWalt 60V FLEXVOLT battery platform, so no outlet, extension cord, or field generator is required. View operating specifications.
Is the battery included?
No. The $999 purchase price is for the On-Hive Fogger tool only. A compatible DeWalt 60V FLEXVOLT battery and charger are sold separately. See battery requirements.
Which battery platform does the fogger use?
The fogger is designed for the DeWalt 60V FLEXVOLT battery platform. Battery and charger are sold separately. Review the specifications.
Does it fit single- and double-deep hives?
Yes. The unit is designed for direct placement on single- and double-deep Langstroth brood configurations. A 5-frame nuc can be treated with the appropriate setup or adapter.
How long does a treatment take?
Approximately 35–60 seconds for a 5-frame nuc, 1.5–2 minutes for a single deep, and 2.5–3 minutes for a double deep. View the operations guide.
How much Hive Health should I use?
Use 150–200 ml for a 5-frame nuc, 300–400 ml for a single deep, and 500–700 ml for a double deep, following the applicable seasonal dosage guidance. View the operations guide.
Can I use it with bees, brood and queens present?
The fogger is designed for applying Hive Health to live colonies. Follow the current Hive Health application guidance. View the operations guide.
Can I use Hive Wash in the fogger?
No. The On-Hive Fogger is intended for Hive Health applications in live colonies. Hive Wash is intended for deadouts and equipment without live bees present. Learn about Hive Health.
Is this only for hobbyist beekeepers?
No. Hobbyists can use one unit, sideliners can add units as they grow, and commercial operators can run multiple foggers in parallel. Compare application methods.
What does a commercial parallel workflow mean?
It means running multiple independently powered foggers at the same time. Each unit treats its own hive while the crew prepares, moves, or refills the others. Request commercial planning.
How do I clean the fogger?
Remove the internal treatment components and follow the cleaning and maintenance guidance after use. Do not store the unit with mixed solution remaining inside. View the operations guide.
Can I use it on Top Bar or Warre hives?
Contact Terra Vera for recommendations for Top Bar, Warre, multiple-box, or other nonstandard hive configurations. Contact Terra Vera.
