Sulfuring
Lexikon
Sulfuring means killing an entire bee colony with burning sulfur in the hive.
Sulfuring means killing an entire bee colony with burning sulfur in the hive. The Bee Competence Center of the Bavarian State Institute for Viticulture and Horticulture describes it as a measure for colonies that can no longer be saved and that pose a danger to the other colonies because of a 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 a delicate one. The ban on killing in Section 4 of the German Animal Welfare Act explicitly refers to vertebrates; bees are invertebrates and are not covered by it. The principle of Section 1, however, applies to every animal: no one may cause an animal pain, suffering, or harm without a reasonable cause. The most important case in practice is American foulbrood. It is notifiable, and under Section 9 of the Bee Disease Ordinance the competent authority orders the killing of the diseased colonies. Instead, the authority can also permit an artificial swarm procedure. The Bee Competence Center therefore explicitly points out that interventions in such cases take place only on the order of the official veterinarian.
Sulfuring cannot be considered a particularly gentle method. Sulfur fumes are also highly toxic to humans. BienenSchweiz requires gloves, long-sleeved clothing, and a respirator 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 does not belong in a lexicon: anyone who thinks a colony may be a case where something like this could be necessary should first contact the responsible bee inspector or the veterinary office.
The most common error in reasoning is to consider every small colony a hopeless case. BienenSchweiz explicitly distinguishes between an ailing colony, that is, one that is incurably sickly, and a small colony with a future. Weak is not the same as sick. And if a notifiable disease is suspected, the expert must be called in before any measure is taken, not afterwards.
