In residential ULV applications, which morning window is commonly used to reduce drift while ensuring coverage?

Explanation:
In ULV residential applications, opportunities to drift are minimized when air is calm and stable. Early morning typically brings the lightest winds and the most stable air, plus cooler temperatures that reduce convective currents. Those calm, cooler conditions help the fine droplets stay closer to the target surfaces rather than being blown away, which enhances coverage around entry points, foundations, and other crevices you’re aiming to treat. The higher humidity and cooler air also slow evaporation a bit, helping droplets remain effective long enough to reach the intended areas. Midday conditions, with stronger solar heating and more convection, tend to spread droplets more and increase drift, while late-night windows can pose safety and practical concerns and may not reliably favor coverage. So, the morning window around early hours provides the best balance of reduced drift and adequate coverage.
