If your EFB infection is not too severe, and it is early in the season, then you are allowed to do a shook swarm onto new foundation. The old frames and brood are burnt, and the hive hardware all scorched. If the EFB comes back in that colony then they have to be killed (with petrol/gasoline) and all the hive contents burnt. However the hive hardware can be scorched and reused.
I found the whole process quite heavy-handed, but it did work, and I reclaimed the cost of materials on my bee disease insurance. I think that there is also a situation in which you can treat with tetracycline, but I don't think they are very keen on this, as the recurrence rate is higher.
I did feel a bit like a criminal, standing back while three guys in official bee-suits went through the hives silently, with the occasional ' I've got another positive over here'; like having your house searched!
However I am grateful that they do keep the diseases under control, as beekeepers here are often quite close together.
