  1. Re: Lost 2 nice colonies in OHs in a month

    Yeah, I don't think it's the bottom entrance. That's pretty standard. Easier for them to carry the dead out.

    The one with the wall exit built into the hinge was the first to go. They had swarmed twice in ten days and the die-off happened a week or so later. I've looked over plenty of designs...
  3. Re: Lost 2 nice colonies in OHs in a month

    By the way, on SHB, no slime anywhere on the comb. the only larvae were down in the mass of dead bees.
  4. Re: Lost 2 nice colonies in OHs in a month

    I thought about that, too. Both were in schools. Lots of possibilities but I only think that scenario would have been deliberate.
    The county is very progressive but I will look into the...
  5. Re: Lost 2 nice colonies in OHs in a month

    Good question. Both are out of direct sunlight and regular room temperature (low to mid 70s)
  6. Re: Lost 2 nice colonies in OHs in a month

    I don't think the entrance was the problem. Both hives have bottom entrances with short tubes that were working just fine before the incident.
  7. Re: Lost 2 nice colonies in OHs in a month

    Thanks for your input. The entrance did become clogged in both cases. Clogged with dead bees. Became a gross, wet mess. Might have been a lot of larvae in there, too. Lots of other larvae were in...
  8. Re: Lost 2 nice colonies in OHs in a month

    Thanks for the thoughts. I manage a third OH that has had its share of difficulties but never anything like this. The location for both is more inner suburban. No farmers nearby. Just looked on Earth...
  9. Lost 2 nice colonies in OHs in a month

    I'm not big on cross-posting but this is driving me nuts so I want to ask in the OH section since there may be special considerations. I posted this in the Pest and Disease section:...
  10. Re: Observation Hives. Heavy adult bee death.

    Sorry about the image attachment above. The image uploader is a bit wonky here. Anyway, no dried "scale" of dead larvae in cells and no ropy goop. This colony was jamb packed with brood. It seems...
  11. Re: Observation Hives. Heavy adult bee death.

    Went back today and decided the colony is lost. Just too many dead bees. Clearly no queen. A handful of queen cells open on the sides. I went specifically looking for signs of AFB or EFB and couldn't...
  12. Re: Observation Hives. Heavy adult bee death.

    Thanks for your input. None of the diseases I have researched seem to apply to adult bee death on this scale. The only thing that I keep coming back to thinking is poisoning or Buttercups. We're...
  13. Observation Hives. Heavy adult bee death.

    I help out with an observation hive on the other side of town. I installed a moderately productive nuc in it in the fall. They fed it as needed. This spring it performed well. Late March, it swarmed....

    Re: double layer or single?

    I work 2 OHs and have just built a third.
    One is a weird mix of 3 deeps up the front with 2 more deeps inside along the bottom. We never see the queen on the front face. It's also brutal to work;...

    Re: Strangest swarm I've ever seen

    So, looks like it must be something in Andrena. 500 species of ground nesting bees in NA.

    Strangest swarm I've ever seen

    Not that I've seen more than a dozen in person but this was really odd. Resident says they have been there at least all day today. They are in low, open ground cover. Maybe 1000 bees. Here's the...

    Sticky: Re: Homemade oxalic acid vaporizer

    Rader, thanks. This is the kind of data I need. I own a dewalt 20v drill with a 5ah battery so, if the process takes 5 minutes, I might be able to do a half dozen hives per battery/charge.

    Sticky: Re: Homemade oxalic acid vaporizer

    I'm fairly new to OV treatment but I had a pretty cool idea and wanted to run it by some folks. I had a friend who scorched her frames and melted some wax leaving it in too long. How can you tell? I...

    Re: serious varroa infestation

    On timing OAV:
    I was lax in treatment last year (with Hopguard) and lost a couple of hives. Bought a nuc and successfully split another so i'm back up to my goal number. Our flow is about done here...

    Re: Plastic foundation vs wax

    How much wax should be added to the plastic foundation? How much is too much? How should it be applied?

    Watched them ignore the tall and go all over the short (of the 2 species by the greenhouse).

    Can you post an update? I'm looking to requeen a few next year.

    This is an excellent question. I have several acres and about an acre total that I want to use to assist my girls (I know an acre won't feed them but it will help). I see several species of Goldenrod...
