Following thieving of two of my hives 4 years ago, I use a branding iron on all my frames, boxes, roofs, floors, excluders, everything with my BBKA membership number but, who will know its mine if spotted 50 miles away. Bee inspectors can check Beebase numbers but not BBKA numbers!! Beekeepers can challenge if BBKA number is not local, if you get to look?
I've branded as deterrent, it won't get my bees back, as we know the thief will empty the bees into a nuc etc and probably burn the hive.
We need to insert a transmitter into the wood that sends a signal that can be tracked if the hive is moved and catch the thief. The technology is already with us to do it but the costs are too high for us hobbyist beekeepers. Unless we can baulk buy?
If the thieves are nicking now rather than waiting for April with wintered bees, stolen for cash??
