I checked a sticky board four weeks after putting in 2 x apitraz strips (newly opened packet) and 2 x apivar (from a previously opened packet). Was surprised to find there were still 40+ mites on the board. Does this mean the treatment isn't working? Or does it mean the treatment is working because the mites are dying? We are told to keep checking mites after putting treatment in but it's hard to find any clear information on what is a normal mite count during this time. Not sure if I should be ok with that mite count or if I should panic. I am wondering now if the previously opened packet of apivar strips may no longer be effective. Perhaps I should put in 2 more of the newly opened apitraz.
