Hi Juanse and all

The original witewipe pads were introduced to Ontario beekeepers by  
Medhat Nasr when he was working for the Ontario Beekeepers  
Association.  Dripac meat pads are soaked with 35-40ml 65% formic acid 
(20ml for single brood chamber hives) and placed on the top bars of  
the hive 6 times at 4 day intervals.  I have done 24 hr mite drops  
during the treatment and found that there is very little change in  
the numbers of mites dropped until the 5th pad is on(16 days) with  
the highest spike coming before the 6th pad is installed.
