    After a long drawn out wait, I have decided to treat with Apistan. I didnt want to do it, but I am getting aprox. 150 varroa a day on the sticky board. I am also seeing deformed bees, almost everyday. The hive is full of bees, lots and lots of them. Does anyone know how long before I start seeing results?

    The standard test method used to be 24 hours
    from the point that the Apistan strips
    were inserted.

    More recently, it has been realized that
    a single 24-hour period was less accurate
    than a 3-day period, as weather could
    impact the drop, so now one counts the
    mites that collect over 3 days, and divide
    by 3 to compare to one's prior 24-hour
    drop counts.

    But if you listen carefully, you can hear
    the little bastards screaming right now.

    Between Aug 1 and Oct 1, I have counted 7,938 mites.I fogged them twice with FGMO and treated with oxalic acid for 4 weeks.
    I do not want to lose my bees, so the APISTAN went in. After I do the count each day, I scrape the stickyboard and take a propane torch to them, I dont hear any screaming , but they sure do sizzle!

    Newbee, what method of vaporizing are you using? Top, bottom, electric, crack pipe, brass or copper, and how much. And what kind of BB.

    How much acid did you use, how did you measure it, and did you close up the bottom for ten minutes afterwards?

    Newbee when I see your mite count you nicely breed the Varroa during the year, even with FGMO.

    So many mites during the long treatment mean your bees had lots of brood and whenever the Varroas hatched the acid killed them.

    You should close the SBB during the treatment otherwise the bees blowing lots of acid out of the hive during evaporations.

    Give them one or two more OA when there is no brood maybe the end of November and the colony is ok for the next season.

    Make sure there is not a beekeeper with untreated colonies in the neighborhood and your bees coming home with a little backpack.

    How might one best vaporize oxalic acid when the hive floors only provide a 3/8" space below the bottom set of combs? (For instance, have commercial flat floors with 3/8" entrances.) The commercially available vaporizers require more space than that.

    I read mixed reviews about top-of-hive treatments. Also, I have read that passive vaporization without some sort of forced(?) ventilation arrangement does not provide a thorough distribution of the vapor.


    ?

    Thanks.

    I used the scoop that came with the vaporizer and yes I did close the entrance. I also left the sliding board in, on the SBB. the weather is not that warm today so I dont expect a high drop until it warms up tommorow.

    EXCELLENT NUMBERS, I wonder if the Oxalic is less effective after a certain threshold. Or maybe there needs to be more care in the treatment. Of the two hives of mine that were treated with O/A ...one has no (Repeat:NO mite drop) The other is at about 100 and will be treated again. Of my 10 hives in the home apiary, 3 will need a treatment. (Mites over 100) The rest are in the 20 to 40 range.
    You can see the high mite drops (In newbee 101) following an O/A tx so it does have an effect.

    Are you continuing to count after putting in Apistan?It will be interesting if there is a big increase in mite fall,but I am thinking the same as Axtmann that the oxalic was getting them as they came out of the brood.Around here there is a lot less brood in the hives than there was several weeks ago.The last 6 weeks have been the 'critical brood raising period' for the winter bees-the critical ones that carry the hive through the winter.If there was a lot of varroa and viruses during that period,the hive has a poor chance of survival.It isnt how many bees are in the hive that is important,it is how many healthy young bees there are.Seeing young bees with DWV at this time of year is a really bad sign.There is a lot of mite damage around the country this year so you arent alone.

    First 48 hrs after Apistan, 586 mites.
    I am wondering if I am a beekeeper or a mitekeeper?

    Cool

    Are these mites counts from just one hive? Wow.

    I use nothing - well, I've gone small cell and the largest count I had on one hive in 24 hours was about 75.

    I put my trays back in and they have been there 3 days. I'll see what I get then.

    My hives are 2 deep with a medium honey super.

    Mine is 2 deeps and 1 shallow super. If your getting 75 per 24 hr period, I think you should do something to treat them.
