    Re: Global Warming

    As far as I know the cheapeake bay used to be a glacier, well I looked outside this morning and Grins is right as the glacier is gone. Now how did that happen if there was no global warming.

    Re: OAV injection location

    drobbins, most of the leaks are around the bottom of the hive and I think the vapor seems to displace the air in the hive so it moves more easily in the direction of the leaking air. Now if you...

    Re: Johno's Easy Vap - Vaporizer

    Tenleez I would continue with the OAV treatments until you no longer see a significant drop of mites then if you can wait about 10 days and do a mite wash on a half cup of bees from open brood.
