Queen Bee
Yes we do have neighbours. Not quite sure what you are getting at here as our bees are kept in out apiaries away from people. Even if they were kept in our garden what is your point? Are you saying that you consider that it is not safe to use in a back garden apiary?
For a back-garden apiary, I think it would raise 'concerns' with the neighbours which might well lead to the bees having to be moved to an out-apiary.
It ain't worth aggravating them. For a small number of hives, in a domestic garden, Oxalic 'trickling' is very nearly as effective, much cheaper, and zero nuisance to the neighbours downwind.
