Hi Dick and all

My understanding is that the bees are looking for protein.  I've seen  
them taking sawdust from my compost.  I don't think we want to know  
about some of the things that they take back to the hive when we  
can't watch them.  I wouldn't worry about this but what about your  
neighbour spraying his dandelions with weed killer.
