Glossary
A handheld tool that burns natural materials (pine needles, burlap, dried herbs) to produce cool, thick smoke. Beekeepers puff smoke into a hive before inspections to calm the bees by masking alarm pheromones and triggering a feeding response.
The bee smoker is one of the oldest and simplest tools in beekeeping, and it remains essentially unchanged because it works so well. A smoker consists of a metal fire chamber with a bellows attached. The beekeeper lights natural fuel inside the chamber, pumps the bellows to get it smoldering, and directs puffs of cool, thick smoke at the hive entrance and between frames.
Smoke affects bees through two mechanisms. First, it disrupts their alarm pheromone communication. When a guard bee perceives a threat, she releases isoamyl acetate (also known as isopentyl acetate), a chemical signal that recruits other bees to defensive action. Smoke masks this pheromone, preventing the cascading alarm response that would otherwise mobilize thousands of defenders.
Second, smoke triggers a primal feeding response. Bees exposed to smoke instinctively begin gorging on honey, an evolutionary behavior likely linked to the association between smoke and wildfire, the threat of needing to abandon the hive. A bee with a full stomach is physically less able (and behaviorally less inclined) to sting, making inspections considerably safer.
Good smoker fuel produces cool, thick, white smoke without excessive heat or toxic fumes. Pine needles are a favorite in Florida because they are abundant, light easily, and burn steadily. Other common fuels include burlap, dried leaves, cotton, wood shavings, dried herbs like lavender or rosemary, and commercial smoker pellets made from compressed wood fiber.
The key is keeping the fire smoldering, not blazing. Hot, thin smoke with visible flame can irritate bees rather than calm them, and sparks can damage comb or injure bees. A well-managed smoker produces a steady stream of dense, room-temperature smoke that drifts through the hive gently.
Over-smoking is a common beginner mistake. A few gentle puffs at the entrance and across the top of the frames is usually sufficient. Too much smoke can panic the colony, cause the queen to run erratically (making her harder to find), and taint the flavor of uncapped honey. Experienced beekeepers use the minimum amount needed and often work sections of large hives without additional smoke once the inspection is underway.
No. Properly used, smoke does not harm bees. It temporarily disrupts their alarm communication and triggers a feeding response. Bees return to normal behavior within minutes of the smoke dissipating. Over-smoking can stress a colony, so experienced beekeepers use the minimum needed.
Some beekeepers work without smoke, particularly with docile bee breeds in calm weather. However, a smoker is considered essential safety equipment for most inspections. Even gentle colonies can become defensive during extended inspections, and having a smoker ready prevents situations from escalating.
It depends on the fuel. Pine needle smoke has a woodsy, campfire-like aroma. Burlap produces a slightly acrid smell. Some beekeepers use dried herbs like lavender or rosemary, which produce pleasant-smelling smoke. The smoke should never smell chemical or synthetic.
