My understanding is that formic acid is a particular nasty chemical and should really be used in a fume cupboard. I believe that it can also be absorbed through the skin. It is not, therefore, without danger to the beekeeper. -- Paul Walton [log in to unmask] Toddington, Bedfordshire, England. Tel. +44 (0)1525 875570
