Rae, in fairness a 4 year old could be stung by bees that are used to pollinate a tomato farm, or from a conventional hive. I don't see why suddenly the BeeHaus could be the harbinger of doom.
The point of the course provision is to introduce interested people to beekeeping via the Omlet site of course. It is not designed to be a hard sell on the beehaus. I show no fewer than 5 types of hive on my course. Once they have attended a course, they go away armed with information about the BBKA, local BKAs, information on where best to site a hive and so on, and they make their minds up about the right hive. If they want they can buy a national and paint it bright green just to feel better.
Anybody could buy a hive at an auction/via a main supplier and start beekeeping having read a book (eg beekeeping for dummies) but most people try and find out as much as possible about the subject first before diving headlong in - which ever hive they choose, unless they are a competent woodworker, they will have to part with cash. As long as the hive does it's job, and in the case of the BeeHaus, it is designed for the smaller beekeeper, not your commercial guys, then that is fine.
At least the BeeHaus comes with information - I can't ever recall receiving advice about bees when purchasing cedar hives in the flat !
Whatever the detractors think about the beehous, it has succeeded in bringing in new interest to the beekeeping sector - and that has to be a good thing - unless you are someone who guards the 'rituals and rites' of beekeeping so jealously you couldn't possibly imagine someone having their own hive until they had studied for at least 10 years.
The same goes for TBH, whether you are a fan or not, they too are bringing new found interest to the hobby.
The more people are interested, the more clout the beekeeping profession will have and that gets my vote.
