Bees are not active during which of the following conditions?

• A. Before dawn
• B. After dusk
• C. When temperatures are less than 55F
• D. All of the above

Answer: (D)

Bees forage only when there’s enough light and warmth. Light guides their activity, so before dawn and after dusk they stay in the hive because there isn’t enough daylight for safe flight. Temperature matters too— insects like bees can’t fly well in the cold, and a common practical threshold is around 55°F. If it’s below that, their flight muscles can’t operate effectively, so they remain inactive or hive-bound. Since each of the listed conditions leads to inactivity, the correct choice is all of the above. In real-world pesticide timing, this means avoid applying when bees would be active—during warm daylight hours, not at dawn, dusk, or when it’s very cold.
