Hi I am living in Czech rep.,
as in whole Europe, we have had very mild winter (arround 0Â°C). We see quite high ammount of the mites in the colonies. Our regular procedure is to use twoo aerosol fumigations before Christmas, when queens are not laying eggs. But this year queens did not stop, so many mites were hidden in coverd cells. What is regular procedures in this mild weather. By the vet authorities we have to fumigate again and to use special treatment for the brood.
