Dripac meat pads are soaked with 35-40 ml , 65% FORMIC ACID........


Hello Bob,

The mitewipe is Dri loc pads. Alberta beekeepers reported that they apply 
mite wipe pads as  2 pads  (total of 80 ml, 65% formic acid / 2 
boxes-hive). They apply the double pads once every 10 days, 3 times in 
late spring and early CND summer. The ambient temperature is >15C. Some 
beekeepers use mitewipe pads during fall, whoever, it gets too cold in our 
area and most of the time it can fail. Results are also too variable. 
Spring treatment if conditions are met, efficacy can be up to 90% +. Once 
again FA has inherited problems with temperature, hive size, cluster size, 
brood, quality of equipment, etc. All of the listed variable will 
determine how much efficacy can be achieved. In Alberta Mitewipe is used 
as a supplementary treatment with oxalic acid or to alternate with Apivar 
to use Apivar once a year. If you read our surveys in the last 3 years, it 
shows that formic acid treatment has been shifted to spring/ late summer 
time to ensure good efficacy.
