To add a bit to the confusion, the Apistan rate has ben recommended at one
    strip for every five frames of brood.   This means that the application rate
    varies according to season.  One may have as many as four strips in a colony
    according to those recommendations.
 
    Our field trials have shown that comparable levels of mite control are
    obtained when two strips are applied to these colonies instead of four.  It
    is also important for the producer to properly place the strips between the
    frames to ensure maximum contact exposure to the bees.
