Oh you are such a pedant Ollie!
Not at all.
I meant to say for the prescribed period
But you didn't, did you? There lies the problem - severely in your court, not mine. So don't try to blame me for your ommissions/mistakes/gung-ho attitude or whatever. Say what you mean and mean what you say.
The other poster was of similar ilk - back-pedalling from I remember Bayvarol being launched in the UK c '97 and it worked a treat = two strips left in the BB over winter. It was only after it was withdrawn to the later claimed and removed them about 2 months later which was little better than the previous post as it still demonstrated a complete and irresponsible inadherence to the instructions from the manufacturer (with the likes of that going on, little wonder our bees have suffered the consequences caused by the few(?) who either didn't know, didn't care or couldn't be bothered to find out).
You potentially told the whole world you were going to ignore the instructions, just like the other poster that left them in all winter. That is just the problem of where resistant mites arise from and the previous behaviour accelerated that problem - that should go uncorrected? I think not.
I am not particularly in favour of your syle - blame me first, then apologise later.
Finman is no better. Apistan, (only) used in the right circumstances, is still a good fall-back when other treatments are ineffective, as in this case. Finman's attitude reduces that chance of a satisfactory outcome and is reprehensible from a supposed respected beek.
