A smoker allows the beekeeper to calm the bees. A few puffs of cool white smoke is often all that is needed. Smoke does two things to the bees: it disrupts their
pheromone (smell) communication, and it causes the bees to gorge themselves on honey. Both conditions cause the bees to become more docile. However, too much smoke, or hot smoke will agitate the colony. Of course, a smoker also requires matches or a lighter, as well as fuel.
