    Default How to treat OH for mites?

    In mid-MD I maintain two OHs. One at Earth Space & Science Lab. One at a Nature Center. Single layer. Shallow frame over three deeps.

    I have never treated for mites. The ESSL swarms every year. Intentionally. I had a couple extra Apivar strips the other day, so I added one to each of the hive entrances. Shown is the very strong ESSL and its entrance. Do you treat for mites somehow? If so, what technique do you use?

    I have rotated Apivar and Apistan in my observation hive. The strips would be more effective if you put them in the brood area instead of in the entrance.

    There's a very small dosage recommendation for OAV. Can you go in when no one else is there? I run a number of them, too, and plan to use mu Provap110 right in the entrance.

    I do mine through a 1/4" hole about 2/3rds of the way up between the 2nd and third frame. I put cotton balls in all the vents wear a mask and have the room closed off. with 6 medium frames I used 2 grams of OA per treatment as I watch the vapor to make sure it gets everywhere and 2 grams sure does. I have done 4 treatments 5 days apart like this and no dead bees or brood. After about 15 minutes the room can again be occupied.

    Setting apivar strips in the hive entrance in such a way the bees run over them has been trialed, and doesn't work.

    i guess there is a lot more bee contact, inside the brood nest.

    I don't treat them. But you could take them outside and run some OAV (oxalic acid vapor) in.
