  1. Re: Smartphone app that listens to bees to tell you what health issues they have

    Hey remember this is the USA the land of the free and the home of most of the lawyers in the world. I dont think anyone can sue me for saying that

    Re: Need help on brood above queen excluder

    Look in the lower boxes for brood, you may have had a supercedure and the young queen might have come into the hive above the queen excluder so it is possible to have a queen above and below which...

    Re: Oxylic acid schedule

    I am wondering that in a heavily infested hive you could have quite a number of those mites feeding under the belly scales of bees and are perhaps not affected by the OAV as they are protected by...

    Re: Band heater vaporizer.

    MSL if you use a thermocouple that is used with a multi meter, the end is just some small wires twisted and fused together, this can be inserted between the bottom of the bowl and a stainless steel...

    Re: Band heater vaporizer.

    When you take the used cap to refill just take your loading spoon and wind it around on the inside of the cap to remove any of the condensed OA from the inside edges of the cap then refill the cap as...

    Re: Oxylic acid schedule

    I have a friend who has just started using OAV for mite control, did mite checks before starting a regimen of 5 treatments 5 days apart. Most of his hives showed low mite infestation but one had...

    Re: Another battle for the bees....

    I have farmers all around me using neonics, however the only losses I have had were some hives close to a neighbor using the insecticide Sevin available in any hardware store, in his vegetable garden.
  8. Re: OA vaporization is probably safe with honey supers - here's my calculations

    One would think that if a significant amount of OA was floating around for some time you would think it would not be necessary to treat with OAV so often as we do. If the bees cart all the crystals...
  9. Re: OA vaporization is probably safe with honey supers - here's my calculations

    As I have been using OAV for about 6 years now you can tell how concerned I am about the regulators and as far as I am concerned if they can keep their bees any better than I can I will still take no...

    Re: 'Good' fondant recipe

    Username, I put the deep saucepan back onto my gas range to heat up the mixture to decrease its viscosity and I also push the pot to one side so that the gas flame really heats up the side of the...

    Re: How long to wait for wash after OAV?

    My feeling on this is to wait 7 to 10 days, give time for any mites you may have in the brood to emerge. I feel that 3 treatments is not sufficient to really make a dent in your mite population as...

    Re: Bee genes questions?

    From what I have heard along the line Mendel tried his breeding efforts on bees but gave up as it did not work out. The belief at that time was that the queen mated within the hive and life would be...

    Re: Varroa mite count

    Depending on the numbers of frames of bees in the hive a 100 mites could be 1% on 10000 bees so figure how many frames of bees. 1000 per frame for mediums or 1500 per frame for deeps.
    Now 100 mites...
  15. Re: OA Vaporization instead of a "traditional" mite counts

    Jeets with your figures at 1,500 bees per frame and 20 frames you would have 30,000 bees in that hive. Divide 30,000 by 100 then 1% would be 300 mites. But only 15 dropped divide 15 by 300 and your...
  16. Re: OA Vaporization instead of a "traditional" mite counts

    This has been discussed in previous threads where if one does a treatment and then counts the mite fall the total bee population can be estimated on frames of bees and therefore the mite fall...

  18. Re: OA vape 5 days vs. 7 days apart - what do you recommend?

    R_V, I have one of those masks but prefer the paper one as it does the job just as well and is a lot more comfortable believe me.

    Re: varroa lifespan

    As far as the mites life cycle is concerned My understanding is that the male never comes out of the cell it was born in so I can not see how one can differentiate from the colors of the fallen mites...
  20. Re: OA vape 5 days vs. 7 days apart - what do you recommend?

    When I am treating inside of closed small rooms such as my study with the observation hive or in the room with my 6 AZ hives I use a 3M 8511 or the other number is N95 which is a paper mask with a...
  21. Re: OA vape 5 days vs. 7 days apart - what do you recommend?

    In the early winter of 2016 while I was working on producing a band heater vaporizer I would do many tests with different combinations to see and time the sublimation period of the device, so on...
  22. Re: OA vape 5 days vs. 7 days apart - what do you recommend?

    There was an article in the ABJ some time back when a beekeeper did a bunch of tests with OA crystals being place on mites that he had glued to pins, some were upside down and a few crystals were...
  23. Re: OA vape 5 days vs. 7 days apart - what do you recommend?

    The OA is never gasified in the hive, there are only fine particles of OA crystals suspended in the air for a shot period of time, while those particles are suspended they are not harming mites. ...
  24. Re: OA vape 5 days vs. 7 days apart - what do you recommend?

    What do we really know about mites, 5 to 11 days having to be phoretic. Surely the foundress mite does not need time to mature and can go back into the cell of larvae when one of the correct age is...
  25. Re: OA vape 5 days vs. 7 days apart - what do you recommend?

    It would also be an interesting experiment to actually sprinkle some of these fine crystals onto some open brood while a frame is held horizontally to see if there is any effect on the brood. If...
