Re: Need advice on brood pattern
Time for the sticky board is over to you, depends how good the sticky board will keep the mites on it, ie do the bees have access to it, or are there ants or whatever that will carry off the mites before you see them.
2 mites in your wash is a major improvement and very encouraging, but it's still more than you want at this time so treatment wise keep walking the walk. It's a nice feeling to know your bees will be a lot more comfortable.
