    Re: Typical size of winter cluster??

    52817
    This is my Carniolan nuc January 2019 (3 seams, depth unknown, but not beyond the top deep). My 8-frame Carniolan hives had 5-6 seams of bees. They all overwintered fine (our winter is very...

    Re: Washington

    After very cold Thanksgiving week, we had a week of fairly warm weather and some foragers brought back small amounts of pollen.

    Re: Ants emptied one box

    I saw videos where a certain orchid (Cymbidium floribundum) was used as a swarm lure for Apis cerana japonica. They simply put a potted plant by empty hive boxes (this won’t work for Apis mellifera)....

    Re: Thank God that’s over- kids are flying

    Yup, the Thanksgiving week was pretty cold (fortunately we had no snow). Yesterday my bees (Carniolan) were flying and some foragers brought back small amounts of pollen. They are still ditching a...

    Re: Ants emptied one box

    Well, if you already have a trap and still got that many ants, I’m not sure whether this would help, but

    Re: Bottom Board Mite Counts

    One thing to remember is a mite drop count can be very inaccurate during winter if dead bees pile up on the screen bottom (and during summer if ants carry away dead mites). During late fall - winter,...

    Re: Bottom Board Mite Counts

    I wait until mid December because I get a better chance to hit the broodless moment (i.e., 2nd OAV a week later gives near-zero drop). But if I saw >20 natural drops per day in mid November, I would...
  8. Re: An absolutely robber proof entrance for a small colony

    Interesting!

    This past October, my smallest and gentlest colony was under attack by yellow jackets. I narrowed the entrance disc to almost one-bee size (YJ here can get through the queen excluder...

    The bees had a couple of foraging afternoons and brought back small amounts pollen (ivy, camellia, mustard-like).

    Re: Bottom Board Mite Counts

    So you got total 30 - 300 mite drops since September? Your September treatment must have worked very well. I have Carniolans in double 8-frame deeps and if I see <10 natural drops /day now, I would...

    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.

    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...
