The bottom boards should be cleaned immediately after the cleansing flight, which is quite early in the year. The flight entrances should be downsized when ventilation decreases considerably WHAT DOES THIS MEAN?: (flaming, washing with Virkon solution) (Finland). In southern Norway, this is done from mid-April to mid-May while food consumption is checked at the same time.
