    [QUOTE=TJC1;1767417]Haven't been able to track this down; posted on a local beekeeper's forum - has anyone seen reference to this study?

    Re: Washington

    It was not overly wet nor cold in the past week and the bees brought back some ivy pollen. Yellow jackets still lurked around the hives, but not too many to cause problems.

    Re: Power For A Vaporizer

    I do not think we would get exposed to 500mg/cubic meter outdoors, but 2 mg/cubic meter is realistic, considering distribution of OA fume is uneven.

    The main point I wanted to make is, the risk...

    Re: Still too many mites

    Was it one hundred per day? It is not super-high, but continue treating until mite drop becomes near-zero. In our climates, where bees can collect ivy pollen until mid-late November, there might be...

    Re: OAV in the winter?

    Yup 45F always worked for me. It is said that >37F is fine, but if you are using a classic wand-type vaporizer inserted from the bottom entrance and if the cluster is one box away from the bottom,...

    Re: Still too many mites

    I think your formic treatment was quite successful. A few years ago I treated one of my hives with MAQS in mid September (it was a spring package so I treated pretty late) and counted mite drop every...

    Re: Still too many mites

    I live about 200km south of you (Seattle area) but our climates are not so different. I think it is now a little too cold for Formic and as you said, you cannot do formic while feeding.

    The bees had a pretty good foraging week for November, and brought back some pollen from ivy, camellia, and viburnum.

    Re: The right number of hives to keep it fun

    Since I bought two packages in spring 2015, I have kept just two hives and sometimes one nuc as a spare. Inspection and mite treatment are no big deal with just a few hives. They produce sufficient...

    Re: Lowest observed foraging temperature

    One of my 3 colonies would fly in upper 40’s and bring back some ivy pollen. The other two would wait until it gets ~50F. We had unusually warm weather last January and the bees foraged on Hazelnut...

    This is what I use (it is quite old). I set it at 12V10A (do NOT use 60A), ‘deep cycle’, and initially ‘charge’. After I insert the vaporizer into the hive and sealed it, I switch from ‘charge’ to...

    About 95% pollen found in my hives came from the ivy (the rest were dandelion/cat’s ear, evening primrose, and jewelweed). I could smell nectar around my hives during a few, precious sunny...

    I found a few ivy flowers among countless flower buds. The bees had found them (i.e., had begun bringing back some ivy pollen) a few weeks earlier.
