Fumagilin-B, 24g

Fumagilin-B is a proven treatment for the prevention and control of Nosema disease in honey bees. Derived from a natural extract produced by Aspergillus fumigatus, it delivers highly specific and effective control against both Nosema ceranae and Nosema apis.

Designed for use in spring and fall/autumn, Fumagilin-B helps reduce Nosema spore levels, leading to healthier colonies, stronger spring build-up, improved winter survival, and enhanced honey production. When used as directed, it is non-toxic to bees and simple to apply, making it a cost-effective solution for beekeepers managing colony health.

Fumagilin-B is mixed into sugar syrup for feeding. For best results, dissolve the product in warm water (95–122°F) before adding sugar and mixing thoroughly. Additional unmedicated syrup may be fed after treatment to ensure adequate nutrition.
