When is the best time to apply chemical controls for wasps?

The best time to apply chemical controls for wasps is early morning or late at night because these times coincide with the natural behavior patterns of wasps. During early morning, temperatures are cooler, and wasps are less active as they are just starting their day. Similarly, late at night, they are returning to their nests and are less likely to be flying around. This reduced activity level lowers the risk of being stung and increases the effectiveness of the pesticide application. Applying controls during these times allows for a more successful extermination while minimizing danger to the person applying the treatment.

In contrast, midday or afternoon applications would likely result in a higher challenge due to greater wasp activity, making it more dangerous and less effective. The option of applying only on weekends does not relate to the behavioral patterns of the wasps and might not coincide with optimal conditions for effective pesticide use.
