Arrestraam German normal window size.
 The arrest window method is for beekeepers who want to avoid medication when treating varroa.
 In this case, one or two empty brood frames are placed in the arrest frame and the queen is locked in it.
 Every seven to nine days the brood frames are replaced with new empty brood frames, a maximum of four times in total.
 Removing residual mites with oxalic acid or lactic acid is now also possible.

 Possible applications of the arrest window:
 - during varroa treatment
 - to better replace old brood frames
 - reduce the queen's brooding activity during honey harvest so that the bees collect more honey
 - to prevent the queen from swarming.
