Pesticide Applicator Training: General Standards SP39-W Practice Test

Protecting bees during pesticide applications relies on minimizing their exposure through product choice, timing, and communication. Applying pesticides when bees are active increases their exposure to residues on flowers and in nectar or pollen, raising the risk of harm to foraging bees and the colony. That’s why this action is not recommended.

Using pesticides with low bee toxicity helps reduce potential harm if bees are exposed. Applying treatments at times when bees are not active—typically when pollinators aren’t foraging—minimizes contact with flowering plants. Notifying beekeepers within a radius (such as 3 miles) or within a certain window before application gives them time to shield or move hives or to choose safer alternatives, further lowering risk.
