Nosema is a problem faced by almost every beekeeper and the main medication to treat it is Fumagilin B. Fumagilin B requires you to mix it with sugar water to be feed to the bees.  Unfortunately the bees get temperamental sometimes and won’t take down medicated sugar water in the fall. The hive might be too full of honey, the temperatures too cold, or the bees just won’t take the sugar. Tony Jadczak, the Maine State Apiarist has developed a interesting way to medicate them. Take a plastic baggie and fill it 1/2 full with 2:1 sugar water syrup. Add 1 rounded teaspoon of Fumagilin B to the syrup and mix well. Place the baggie directly onto the frames on the super. Cut several small slits with an exacto knife. Use a feeding shim to give the bees some space. You can drizzle a small amount of syrup onto the frames so the bees can find it. Just make sure to remove the bag when it is empty as the bees will tend to propolize it down quickly.
