The time of year is here when spring cleaning and feeding are in order. Along with that the books recommend feeding Fumidil-B with syrup. The only thing that the books don't say is: How often? I fed syrup with Fumidil last fall. I thought I was to do it again in the spring but some information passed on the BEE-L leads me to believe that that is overkill. What are the guidelines re: use of Fumidil? Mark Egloff [log in to unmask]
