  1. Re: Those who advocate OA as a summer treatment, what do you make of this?

    I looked into OA kit costs. One I found seems rather pricey with a short shelf life. That will also deter even the keeners.

    There's many advantages to being able to treat during the summer...
  2. Re: Those who advocate OA as a summer treatment, what do you make of this?

    The problem is most beekeepers don't have the ability to test oxalic acid content of their honey. I don't even know where to begin to gain experience with that.
  3. Re: Those who advocate OA as a summer treatment, what do you make of this?

    It is all very confusing the chasm between what is researched, what people say to do, and what people might actually be doing. This leads to the frustration around figuring our what works and when,...

    Re: Threshold for mite treatment

    With many reports of bees surviving with high mite counts I think it's more useful to treat only if I see them doing damage. Of course it doesn't require as much wondering, observation, judgment to...

    Re: My TF foundationless experiment

    Yes, I've seen it too. I imagine it happens when there is lots of mites or little brood.



    If the mites are virulent, and if the bees are susceptible, you will likely breed lots of mites. I have...

    Re: Bees building comb above the bars

    I'd rather not go against there behaviour either. When I add boxes above, I suspect I might be going against they way they normally expect to organize their nest.

    The problem is if I didn't add...

    Re: Bees building comb above the bars

    There was some research conducted in Wales trying to find honey with antibacterial properties. It turns out the honey that was the most active all came from warré colonies. So there is now...

    Re: Basswood

    There is a document here that discusses optimal conditions for a few different blooms. It's european so it's discussed under the section titled 'Tilia (lime)'.

    Some of the comments in that...
  9. Anyone have success combining queenless with virgin queen?

    I've heard combining with virgin queens can be tough. Any positive experiences?

    I figure if I wait till the queen was mated, the queenless hive might develop laying workers.

    Is it easier to...
  10. Re: City beekeeping and swarm prevention

    As an urban beekeeper I agree with you.

    "3. Cull queen cells"

    I think this is dangerous. I doesn't seem to change their minds. They just keep building cells. If they are far enough along,...
  11. Re: So what comes after dandelions for big nectar flows?

    @dabbler I've mainly used gdd to attempt some correlation with swarming. I had mixed results with that but did keep track of blooms all season for a few years. For me they seem to really start in the...
  12. Re: So what comes after dandelions for big nectar flows?

    Maple, Apple, willow have been blooming here as well as some other fruit trees (mulberries, cherries, apricots, plums). I saw a few on the garlic mustard:

  13. Re: A look at how I like to setup my warré hives

    Thanks Chuck, I had some fun doing it.
  14. A look at how I like to setup my warré hives

    I was checking out how they over wintered and thought it would be a good opportunity to share what my apiary looks like:

  15. Re: Magnifying glass to detect varroa resistant bees + a virus that block DWV

    Thanks Ray. I did search the forums before posting, but I could only find references to him in posts with a long list of references. No actual discussion.

    Seems like I came up empty because the...
  16. Re: Magnifying glass to detect varroa resistant bees + a virus that block DWV

    Of course, but if everyone did, what he did would most people end up with DWV blocking powers? Or just a few of us?

  18. Re: Warre's original roof VS Heaf's variation - Which is better?

    You could Ask David about his experience. He responds to questions daily on his yahoo group. I know I've heard him talk about mouse boards, I wouldn't be surprised if he normally uses them.

    I...

    Re: double-wall construction?

    40 degrees F is the best temperature for wintering bees (when there is nothing for them to forage anyway)


    Are you basing this idea on the Southwick experiment?

    Re: double-wall construction?

    The problem I see with putting to much into this comparison is that people usually sleep on the bottom of a tent. Bees move up.

    Tent's are meant for temporary, quick + easy shelter. If you were...

    Re: double-wall construction?

    What about the cost of time spent in wrapping hives? Cost of a day in the apiary every year putting on tar paper vs building more permanently insulated boxes?

    This old bee journal seems to suggest...
  22. Would your remove a 4th box with only some pollen?

    My goal for Toronto winters with a strong hive is at least 2 boxes wroth of honey and 3 boxes in total.

    In practice I've found it hard to balance things right so they don't get over crowded in the...

    I will acknowledge this as a possibility, but I don't have any reason to believe absolutely that it's so incredibly ineffective.

    Re: Drone comb loaded with mites

    Randy Oliver seems to feel it might be as high as 40% of the phoretic mites.




    In this context, I'm mainly looking at it to provide some indication of overall infestation levels. The problem...

    Re: Drone comb loaded with mites

    Thing is it did get 35 after the drone comb emerged. Earlier this year I sugared a split raising it's own queen during the broodless period and saw a similar drop. In both heavily and mildly infested...
