    Default Varroa Mite Wash of Dead Bees.

    After reading a post about a dead out, is it possible to do an alcohol wash to count mites on dead bees from a dead out?
    How many mites on dead out bees are too many? >3%?
    Do the mites die on the bee or do they leave and try to find another bee? Or depends on how they died?
    Where exactly do mites hide and feed on the bee? I have looked and have yet to find a mite on a bee.

    You can use water with some washing up liquid.A paper coffee filter will show up the mites very well, you can watch the process here: start at 3:50

    The one time I tried I didn't find mites on dead bees. Not to say it cannot happen though.

    But I suspect that if the bee is dead the mite up and walks off.

    Uncapping dead brood that's still fully sealed, and examining the contents can yield results though.

    You might also like to take a look at Randy Oliver's post about 'Mite sampling methods and thresholds' on his site 'Scientific Beekeeping'.http://scientificbeekeeping.com/figh...mite-sampling/

    He describes how to do an alcohol wash (and other sampling methods) plus has a section on manageable mite count thresholds.

    Neither of those address the post which is DEAD bees.... I should have a dead out I can check tomorrow... I am very curious also. I assumed all themites would have already dropped of... but that may not be a valid point....

    I look on the bottom board for mites. I never saw a significant amount on dead bees. I think they mostly fall off and abandon a dead bee in search of a live one.

    Of course you could do an alcohol wash of bees from a deadout....but I doubt if the results would be significant in any way.

    I find them in dead winter clusters but that may be because of the cold environment and may not happen in warmer temps.
    Varroa can hide between the thorax and abdomen and also between segments of the abdomen.
