Walter,

I have been using formic for years and currently use MAQS. I am guided by mite counts on sticky boards and find that treatment is required in April, perhaps again in June (just before moving into mountains for fireweed) and then in Sept.  In the past five years, I have also used oxalic acid dribble in mid to late Nov. and then again in mid Jan (this is a pre-emptive strike).  Queens are laying eggs by late Jan.  As of mid April, mite loads appear to be low and bee populations are growing well.

Some here in Canada use oxalic in the fall as a secondary treatment and
definitely not when brood is present.
But resistance to Formic,

Anyone????
