    Re: Washington

    On January 3rd, I saw my bees bringing back some pollen for the first time since early December.

    Looked several Japanese websites and it seems that 7 mm works fine against the giant hornet.

    Re: Dead outs

    I guess it is crystalized nectar; this photo was shot in late October after the ivy flow (ivy nectar easily gets crystalized).

    OMG thanks for the video. I have heard that in some area in Japan they drink ‘giant hornet liqueur’ and enjoy stir-fried larvae……

    Re: Washington

    It was not cold but rained often during the past two weeks. The bees had several flying opportunities but I did not see them bringing back pollen.

    Re: Typical size of winter cluster??

    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...

    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)....

    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...

    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...

    Interesting!

    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...

    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...

    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.

    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...
