If AFB is detected

  • Shake adult bees, and requeen with hygienic stock.
  • Burn hive equipment.
  • Outer covers, inner covers and bottom boards without cracks or rotten wood can be scorched with a blowtorch on each surface until charred black. Scrape off all wax and propolis before scorching.
  • Disinfect all hive tools, including smokers. Scrub surfaces thoroughly with steel wool, then wash equipment with soapy water with some added bleach.
  • As a last resort, tylosin (trade name Tylan¬©, a registered antibiotic) can be used. Oxytetracycline (trade name Terramycin¬©) is widely resistant to the AFB pathogen and is not recommended.
  • Beginning in 2017, the FDA requires a new procedure for beekeepers to obtain antibiotics. See details here.
  • Tylan can be used only after the disease has been observed in the brood, and can not be used for prophylactic use.
