What Is Micron Diameter and Why It Matters
Micron size describes droplet diameter. Too large and droplets fall quickly; too small and they may drift away or evaporate before contact. Matching size to pest behavior is the core of ULV efficacy.
Ideal Micron Range for Mosquitoes
Flying mosquitoes are typically targeted with fine aerosols—often around the mid-30 micron band in outdoor adulticiding—so droplets stay aloft in the flight zone. Many Duru vehicle settings use a 35-micron reference for this reason.
Why Houseflies Need Larger Microns
Houseflies rest on surfaces and are larger targets. Slightly larger droplets improve deposition on walls, bins, and resting sites versus ultra-fine mist alone.
Consequences of Wrong Micron Settings
Wrong settings waste chemical, create uneven kill, and fuel citizen complaints. Document targets per pest and re-check nozzles each season.
