I have just applied 'Neem' insecticide to a large number of Rugosa and
climbing roses that are being used by bumblebees for pollen.   The label
said 'safe for honeybees'.  The roses are being chewed to nothing by
sawfly larvae  (horrible things - how a  hymenopteran stoop to such
disgusting pursuits?).
 
Do any of the beekeepers have any experience with this chemical?
If the bumblebees collect Neem-loaded pollen and take it home, will
it hurt them?
