    I checked my best hive today.
    I have not treated this hive
    for 7 weeks or so due to anticipated honey harvest.
    I have not cleaned the bottom board for about the same amount of time. Two week Mite count on July 15 was 6.
    I pulled the SBB (white cardboard) and used my magnifying glass and good reading glasses and found 40 -50 mites in the thick debris...that is an 8 week count. I have not treated for a few months due to honey. I fogged in May, June and early july. I have nearly no mites in the other two hives where i fogged a few more times in Aug and Sept. Do i have a major mite issue here??

    i was under the impression that 40-50 mites a DAY represented a problem (threshold for treatment.) you're talking about an average drop of about 1 mite per 24 hours - granted, i'm new at this, but that sounds excellent to me.

    Get a sample jar, and do a mite sample.

    Windsheld fluid works great, strain through a wire mesh, and then the liquid thorugh a kleanex. Count the mites over the number of bees in your sample.

    Our thresholds are 1% in spring, 5% in fall.

    The hive I referred to above is what i call Hive # 1 I did a 24 hour check of the bottom board today. Wow!!!! 14 +-mites in one day !! Is that
    trouble? I have honey supers on. Will remove any day now but I am going to do the Food Grade Mineral oil fogging immediately, then I'll add the Thymol fogging when i pull the supers off.
    I am not sure that is enough.

    By percent you mean # of mites as percentage of # of bees Correct ?

    Hive #2 four day mite drop on the bottom board is 15+-

    Hive #3 four day mite drop on the BB is 25+

    In hive three i frooze three honey frames with wax moth holes in the wax and foundation.

    Are my bees doomed or what ????

    Forgot to asdd: I thought i had no mites in hive 2 and 3. I started this thread before I did the four day check of the bot board. Guess i was wrong.

    I cant relate to mite drop, for dont monitor my infestations in that manner. The most efficient and accurate method is a mite roll, or wash.
    take a sample, wash off the mites and count mites / bee in the sample.

    Any rate, continue your monitoring during your FGMO treatments. Then consider if it was worth your while.

    jamiev . . .

    This time of year, w/ lots of pollen collection and other hive debris falling, it's very hard to see (and count) mites if the sticky board if left in place longer than 3 days (maybe 4 days [img]smile.gif[/img] )

    If you have an average 24hr count (3 days divided by 3) of 15 or 20 this time of year, you dont have a mite problem NOW (maybe next year).

    A stick board under a screen bottom board is the most sensitive (most effective [http://nanaimo.ark.com/~varipm.htm]) and accurate than any other method if used over a sufficient time period [Ref 16, p163].

    Jamiev:

    You are above the threshold of 4 mites per 100. (Ian says 5) At any rate you have at least 9 according to your sugar roll test. Sugar rolls do not dislodge all the mites, that is why I say at least 9. You are right in saying there are many more mites in the capped brood. I would use Mite-Away II immediately.
