Which time of day is liquid pesticide application less hazardous to pollinators?

The least hazardous time for liquid pesticide application to pollinators is during the late night. This is because many pollinators, such as bees, are less active during the nighttime hours when it is dark and they are likely to be within their hives or resting. Applying pesticides when pollinators are inactive minimizes the risk of them coming into contact with harmful chemicals.

Morning hours and early afternoons are times when many pollinators, especially bees, are actively foraging for nectar and pollen, which makes these periods riskier for pesticide application. The afternoon can still have active pollinator activity, depending on the specific environment and time of year. Therefore, the late night is recognized as a safer timeframe for applying pesticides to reduce the impact on these essential insects.
