How are the bees impacted?
Wildfire smoke drastically impacts honeybees by disrupting their navigation, impairing their ability to forage, and stressing the colony. Prolonged exposure to smoke and ash can lower activity levels and introduce toxins that affect bee survival. [1, 2, 3]
The specific ways wildfire smoke affects honeybees include:
* Disrupted Navigation: Smoke distorts the polarized light in the sky that bees use as a celestial compass to orient themselves. This makes it incredibly difficult for foragers to find food sources or safely navigate back to the hive. [1, 2, 3]
* Impaired Foraging and Reduced Honey Yield: Because they struggle to navigate and breathe, foraging bees become much less active. To survive, bees consume heavy amounts of their stored honey to prepare for what they perceive as an emergency. Combined with ash covering surrounding flora, this can lead to catastrophic drops in honey production. [1, 2, 3, 4, 5]
* Sensory Interruption: Smoke scrambles the chemical signals bees use to communicate. Just as beekeepers use smoke to calm bees by masking their alarm pheromones, heavy wildfire smoke prevents them from communicating danger or coordinating the defense of their hive. [1, 2, 3, 4, 5]
* Toxicity and Mortality: Airborne pollutants like PM2.5 in heavy smoke can be highly toxic to insects. Ash can interfere with their ability to breathe, smell, and taste. [1, 2, 3]

What Do Honey Bee Colonies Do During a Raging Wildfire?
Bees react to smoke by:
Fanning, Motion, Flight, Ingesting nectar and honey.
Smoke disrupts their defensive behavior.
