Sulfuring
Lexikon
Sulfuring refers to killing an entire honey bee colony by burning sulfur inside the hive.
Sulfuring refers to killing an entire honey bee colony by burning sulfur inside the hive. The Bee Center of the Bavarian State Institute for Viticulture and Horticulture (LWG) describes it as a measure for colonies that can no longer be saved and that pose a danger to the remaining colonies because of disease, for example because bees and comb material are carried on through robbing or drifting. The bees and combs are then disposed of safely, and the hives are cleaned and disinfected.
Legally, the term is delicate, and this applies specifically in Germany. The prohibition on killing in Section 4 of the German Animal Welfare Act refers explicitly to vertebrates; bees are invertebrates and are not covered by it. The principle in Section 1, however, applies to every animal: no one may inflict pain, suffering, or harm on an animal without a reasonable cause. The most important case in practice is American foulbrood. It is a notifiable disease, and under Section 9 of the German Bee Disease Ordinance the competent authority orders the killing of colonies affected by the disease. The authority can instead permit an artificial swarm procedure. The Bee Center therefore explicitly points out that interventions in such cases may only take place on the order of the official veterinarian.
Describing it as a particularly humane method does not hold up. Sulfur fumes are highly toxic to humans as well. BienenSchweiz, the Swiss beekeepers' association, requires gloves, long-sleeved clothing, and a protective mask with an activated-carbon filter for this work, and reserves the use of liquid sulfur for the bee inspector. A step-by-step guide therefore has no place in an encyclopedia: anyone who believes a colony is a case where this might be necessary should first contact the responsible certified bee inspector or the veterinary office.
The most common misconception is to regard every small colony as a hopeless case. BienenSchweiz explicitly distinguishes between a 'serbelnde' colony, one that is incurably ailing, and a small colony that still has a future. Weak is not the same as sick. And if a notifiable disease is suspected, the specialist must be consulted before any measure is taken, not afterward.
