Sacbrood Disease

Sacbrood is a viral disease that appears in spring and early summer.

Symptoms

• Uncapped or partially capped dead larvae.
• Dead larvae appear bloated.
• Larvae change colour from white to brown.
• The larval head is darker than the rest of the body.
• The larval skin is hard and leathery.

Treatment

Because sacbrood is a viral infection, there is no treatment. Manage the hives to minimize stress. Requeening may be necessary if the hive is heavily infected.
