Please can anyone advise. I have a compost bin which hasn't been used for sometime. Whilst working in the garden yesterday I noticed bees going in and out of the opening of the hatch at the base of the container. I am assuming there is a nest in there, as they wouldn't be collecting pollen from in there. If there is a nest, I don't want to disturb them, but is it likely they will remain there or will they move on at the end of the season? I would like, eventually, to use the compost bin again, but I don't want to spoil the nest. Can you advise of the best course of action please.
