Time for artificial swarming has arrived - so the two halves of a colony can
be treated efficiently for Varooa when broodless.
Does anyone know how to buy oxalic in UK?  Is there a trade name at say
builders' merchants?
MAFF/ DEFRA pamplet 'Managing Varooa' states: '3.2-4.2% acid solution in 60%
sucrose trickled over combs of bees; 2.5ml per brood comb'.  Can anyone
unpack the meaning?  How do u make a 60% sucrose solution starting with a
packet of dry sugar.  How do u add the right amount of acid for say 3.5%
acid solution?
Help from the scientifically literate   would be appreciated.
