  1. Re: Two questions on getting rid of yellojackets

    The nests are annual. The queens die off in autumn, and only the young queens survive the winter, to establish new nests next spring. So you're unlikely to have one in the same place two years...

    Re: Efb

    We take EFB more seriously this side of the Atlantic. It's a notifiable disease, and it's either treated officially by the bee inspector, with antibiotic and shaking onto new comb, or in a bad case...
  3. Re: Two questions on getting rid of yellojackets

    Reduce your entrances and you won't have a problem. Wasps will always be predators, but we make our bees vulnerable by using wide-open entrances which they don't need, and which are hard to defend.

    Re: yellowjackets again

    I use permanently reduced entrances, about four inches across and half an inch deep. This time of year there are usually more dead wasps than bees outside the hives, and they're never a problem...

    Re: Favorite Mite treatment

    I use the liquid. I'm in a position to pick a mild day; I don't know whether it would be practical to open a hive to apply it in a really cold winter.

    Re: wax moth left me a present.

    Do you know which wax moth you've got? Greater is a menace, but lesser is endemic in my hives, and never does significant damage.

    Re: Reuse Wax

    I don't think AFB spores entombed in wax are infective.

    Re: Tansy Ragwort. Should I worry?

    Even then, it's said that if you leave it to mature for a few months, the honey is OK. I always have a few ragwort plants around, and nobody's been poisoned yet.

    Re: How do you reclaim moldy frames?

    I found that once I started using OMF's, most of the mould disappeared. The only exception was when pollen went mouldy, and that was never as bad as described. Bees soon clean it up.

    Re: Varroa questions

    I think the answer has to be robbing and drifting, plus the odd influx of bees from a collapsing colony.

    Re: What killed the bees?

    A swarm I picked up last year did much the same. It hardly brought in any honey during the autumn; the weather wasn't good, but other colonies brought in enough to winter on comfortably. Over the...
  12. Re: Randy Oliver spoke at Virginia State Beekeepers Assoc Mtg

    I'm not sure exactly what was going on in relation to this virus before varroa arrived, but it presumably existed, and must have been vectored somehow.

    There seems to be considerable variation in...

    Poll: Re: A chemical poll

    You can still get it because people will still buy it. It doesn't work round here but there are still people putting it in hives. A couple of years ago I acquired a hive with six strips in it, all...

    Re: Wasps that are not yellowjackets

    I use permanently reduced entrances, and the only time I ever get a wasp problem is when they get into a weak hive somewhere away from the entrance.

    Re: Nosema caused hive crash?

    Dysentery can be caused by nosema, but there are other things as well. I find it tends to appear any time there's somthing wrong in a hive, or when they've been confined by long cold periods, and...

    Maybe wasp larvae don't produce whatever substance it is that attracts the mites to them.

    Re: invaders

    Close the entrances up small to make it easier for the bees to defend their hives. I have mine on mesh floors and permanently reduced entrances, and have very few wasp problems.

    Re: Dwv?

    Last spring, I saw DWV in one of my hives. It was a hybrid strain in which about half the bees were black, and the rest had a yellow stripe. It was expanding fast, and it wasn't warm enough to use...

    Are they taking active bees, in flight or from the hive entrance, or are they taking crawlers? I've watched our social wasps (equivalent to your yellowjackets) taking crawlers manyt times, but I've...

    Re: Ants eating dead varroa

    I haven't seen ants removing varroa, but there are always a few on my trays, and dead varroa are undoubtedly removed. Ants have to be the prime suspect.

    Tanging originally related to a medieval law that if you followed a swarm, banging on something, then it remained your property. The law is long defunct, but the myths go on!

    Re: Do mice or rats eat wet comb?

    Rats will create havoc with comb. I don't know why so few beekeeping books mention them as pests.
