What causes European foul brood?
European foulbrood (EFB) is a brood disease of honeybees caused by the bacterium Melissococcus pluton. The disease is endemic throughout eastern Australia, but is not known to occur in Western Australia. Worker, drone and queen bee larvae are all susceptible to EFB infection.
What does European foulbrood smell like?
an uneven or patchy brood pattern. dead and discoloured larvae in uncapped cells; in some circumstances larvae may die after capping. infection with EFB may sometimes have a strong ammonia-like (sometimes described as sour) smell.
How do you treat EFB?
The only product labeled for control of EFB is Terramycin (Oxytetracycline hydrochloride). If the colony is infected it is important to treat 3 times with Terramycin 5 to 7 days apart. Re-queening may help by breaking the brood cycle. The shook swarm method and a good nectar flow will also clear up EFB.
Can bees recover from EFB?
While honey bee colonies can spontaneously recover from this disease on their own, EFB causes economic hardship for beekeepers, especially since it strikes in the spring just as many people in the industry are building up their colonies for the season.
How do I get rid of European foul brood?
EFB infected colonies can be treated with an antibiotic (oxytetracycline, Terramycin), by providing feed (pollen and sugar water), shaking adult bees onto clean foundation and disposing of old comb, and re-queening. Mild infections may clear up on their own with a good nectar flow and providing feed.
Does EFB affect honey?
European foulbrood (Melissococcus plutonius), often referred to simply as EFB, is a bacterial disease that affects western honey bee (Apis mellifera) brood.
What does AFB smell like?

- Sunken cappings.
- Off center holes in cappings.
- Larval scale.
- Caramel color of dead larvae*

What do I do with old brood frames?
Rotating brood frames is considered good beekeeping practice for the health of the colony – it’s recommended to cycle them out in a 2 to 5-year cycle. The start of spring is a great opportunity to swap out old brood frames with fresh ones, which can be easily done during a brood box inspection.
What is the white stuff on honeycomb?
Contrary to what may first come to mind, the white chunks or crystals found on honeycombs are not pests or disease infestation. This is simply crystallized honey. The crystallization of honey is a natural occurrence that transforms liquid honey into a solid substance.
