For one or two hives it's not worth doing at all. If you get a really big outbreak it can be worthwhile. It certainly can be dangerous , 160 degrees plus is getting up there. Flareups aren't as bad as people think as long as you're not near a building and as long as you don't do anything stupid like chucking water on it. I have a removable fire tray and if it does catch fire I just remove the tray and it soon loses temperature and goes out.true, however is it worth doing?
