I collected all the feeders from my apiaries yesterday. This morning I put the boiler on to provide hot water to clean them up. I decided to tidy up the bee shed whilst waiting for the boiler. It took me 2 hours. I pulled everything out and re-organised the crates and boxes and their contents. To my joy I found a box with 50 national brood frames in it. I spent a week in the Spring saying I thought I had some! I then went and bought some! Oh the joy. I will not need to buy any new frames for at least 5 years.
I washed the feeders in washing soda and thick bleach, rinsed them all and allowed them to dry in the sunshine before packing them away.
