  1. Re: How many OAV treatments in winter can they tolerate?

    Looks like there WAS a negative effect of multiple treatments, a 4% decline in brood. That's only for 2 treatments.

    For more, say 5 treatments, in the fall and winter - could be as high as 20%...
  2. Re: How many OAV treatments in winter can they tolerate?

    Am I guaranteed not to kill hives if I treat with OAV twice or more when there's snow on the ground?
  3. Re: How many OAV treatments in winter can they tolerate?

    I'm not asking about October treatments, I'm asking about November, December/ January treatments in very cold climates where snow accumulates and doesn't go away.

    Whether or not hives in those...
  4. How many OAV treatments in winter can they tolerate?

    Curious as to how many OAV treatments bees can tolerate before dying in the winter.

    I've treated once in the late fall, but I've read that some beekeepers treat AGAIN in December, if there's a...

    Re: OAV, putting the risk in perspective

    The current "law" only exists in the US and Canada.

    Elsewhere, OAV with honey supers present isn't against the law. It's only "discouraged".

    I feel that it's important to make that clear.
  6. Re: Is it feasible to control swarming without performing a spring split?

    Nancy, would you be willing to share what exactly you look for when you tip up every brood box and look under it?

    I assume this means you look under every box, but if you could share what...

    Re: Black Friday Sales

    Mann lake's sale was a little disappointing.

    I was hoping they'd be selling unassembled frames on black friday sale.

    Re: OAV, putting the risk in perspective

    Sounds similar to a previous thread here on beesource which did similar math, indicating that OAV is perfectly safe to use with honey supers present.

    Re: Black Friday Sales

    Now I don't feel so bad not buying their overpriced products.

    I don't know anywhere else to buy foundation for lower prices, however.

    When did Mann lake get purchased? Who bought them?
  12. Re: Advice on finding properties to place beehives?

    Finally got a response from someone.

    Sounds like they're happy to host numerous hives (which is what I need).

    Haven't met them yet, but did talk to them on the phone. I can't really tell if...
  13. Re: Can Palmer Style Double Nucs be used to produce Honey?

    You have a common super with NO divisions?

    So you're saying that the bees, divided in the bottom 2 boxes, do not cross over in the honey super? Or do you put a queen excluder between the 2nd...

    Re: Johno's Easy Vap - Vaporizer

    What's the general opinion here on very late, Winter - extremely cold weather OAV treatment?

    In my area, temps will not be above 43F, and will be below freezing at night.

    I've seen others...

  17. How do bees ventilate in the winter?

    Quick question:

    How exactly do bees ventilate in the winter? Do they fan the air, or is it completely passive?

    This is in regards to very low temperatures, well below 0C (32F).

    Thanks.

    OAV in the winter?

    What's the general consensus about OAV in the winter?

    Temperatures will NOT get above 50F for the forseeable future. Is it still safe to use OAV on a clustered hive in 45F degree weather?

    Re: I need to move my hives. When is best?

    It sounds like the more experienced beekeepers on here are saying that after several days of winter clustering, they automatically re-orient during a cleansing flight?

    Another positive testimonial for formic.

    OAV is organic as well.

    Re: Still too many mites

    If someone has 50 hives, that's $1000 just to treat for mites.

    Nucs sell for about $150-180, depending on your location.

    that's 6 nucs just to pay for treatments.

    That sounds like a very expensive mite management strategy.

    Re: Still too many mites

    It'd be one thing if MAQS and Formic pro were free. But they're not. If they were free, I'd consider trying these products.
  24. Re: Why the heck won't they gain weight (after ALOT of feeding).

    I wasn't able to find any prices online.

    Does anyone here know what sort of prices this schedule 77 syrup goes for, compared to regular sugar ?
