I’m not sure this is the main reason. Even if I don’t tell where it’s from they don’t want it. It’s just this stupid “I’ve done it this way since 50 years” thing. “We always did it like this” is the sentence I hate the most. Sure, some things are tried and proven, but what’s bad about trying something new? In Germany we have an enormous range of hive sizes, they often differ only by a few mm. And within one size, there are several different “systems” which are of course incompatible with each other. The only reason is that every wannabe bee-god invented his own size and consideres that the holy grail of bee keeping… And there are FIGHTS among beekeepers which size is the best. And everyone considers the users of other sizes as beeing stupid or neglecting their bees or something. As if the bees cared about the length and width of their comb… Luckily this is mostly limited to the older folks. Younger people start to become more open minded, at least concerning hive sizes and even bee races! Buckfast was considered “the enemy”, I even heard about bee keepers who destroyed buckfast hives, but slowly “the other bee” gets established and accepted.
Same thing with this item
German store, german explanation… In short, this thing made of QE and one-way flaps will prevent your queen from leaving the hive when they swarm, she’ll be trapped inside the cage and you can lure the swarm into a box using her, or do whatever you like to do to prevent or handle swarming. And it catches unwanted drones before they can leave the hive, i.e. from an aggressive hive or whatsoever.
I’m pretty sure this is a german invention, at least I first saw and bought it from a local store (after I already pondered something like that last year, but didn’t have the tools and equipment to build one. I thought about a kind of tunnel out of the trap to guide Madame into a swarm box). I just asked for help and ideas how to mount it on my magazine, since the bottom board is not flush with the back side, so it can’t be fit snug to the box. And there was no description of how to attach it, there are no knobs or anything. But instead of figuring out a way to handle the thing, people started debating on whether this might work or not, one even said the queen would be cut into pieces with it… and again I was told to throw it away.
And I still have no idea how to get the trap onto the hive…
