I am a new Bee-l user.  I am also a hobby beekeeper that had all (4)
of my hives die last year from varro.
This year I would like to find something that will help me evaluate
mite treatments.  I read an article that said that a sticky board
could be such a devise.  The author said that screen should be put
over the sticky board to let the bees walk on it , but allow the dead
mites to fall through and be observed and counted.  Does any one know
what size screen could be used to advantage?
 
This information would may  not measure up to the caliber that I
have observed be discussed on Bee-l so,  please send me the suggection if you have
a suggestion.
 
Thank you, James Peterson
