Which time window is widely recognized as a preferred ULV timing?

Explanation:
ULV timing is all about catching the pests when they’re most likely to fly and encounter the spray. For mosquitoes, activity ramps up at dusk, with many species taking off as daylight fades. Spraying about a half hour before sunset places the ultra-fine droplets in the air right as mosquitoes begin to emerge and move, increasing the chance they contact the insecticide. This timing also tends to come with calmer, more predictable winds and when people are typically indoors, which helps reduce drift and potential exposure. Spraying closer to or after sunset can miss the peak flight activity, and spraying in the heat of the day often yields poorer deposition and quicker droplet evaporation. So starting the ULV spray about 30 minutes before sunset hits the sweet spot for maximizing effectiveness while minimizing risk.
