Dead outs are normally discovered on those occasional mid to late Winter days when the sun shines and the temperature rises high enough to allow the bees to wake up and make some cleansing flights. Your blood flows with the sound of the bees flying and you hope for strong hives coming out of Winter. Yes, a few hives are active, but there is one hive that seems strangely quiet. No regular traffic at the entrance. Maybe a bee or two investigating an upper entrance or browsing about onthe bottom board where the mouse guard prevented intruders from taking up residence last Fall. There are a few dead bees at the entrance. That means it's time for a hive check.
