When is the best time to fog for mosquitoes?

Fogging for mosquitoes is most effective at dusk, which is typically when they are beginning to come out to feed. Mosquitoes are crepuscular, meaning they are most active during the twilight hours of dawn and dusk. During this time, they are more likely to encounter fogging solutions as they search for hosts.

Fogging at this time takes advantage of peak mosquito activity, allowing the insecticide to effectively target the adult mosquito population as they become active after their daytime rest. This timing also minimizes disturbances to certain beneficial insects and other wildlife that may be more active during the day or night. Consequently, the choice of dusk for fogging maximizes the potential for reducing mosquito populations effectively.
