Hi Esad, do you know if these dead bees are from one hive or more? If they died insid e hive too and they do feces inside hive, it is nosema. The best way is cont racting hive´s area for better temperature inside. We used for treatment Fum agilin too, but it is much expansive and is better to kill the colony than t reat they. Look, what they do on "hive-door" ( cesno ), how they move, if they can fly normal and next. Martin --- Odchozí zpráva neobsahuje viry. Zkontrolováno antivirovým systémem AVG (http://www.grisoft.cz).
