Reading a lot of posts about people losing bees to drowning when they feed syrup.
A float, or a few things floating on the syrup might look like they will work, but often the bees drown.
So I've posted a pic of a good way to do it, this way I've never lost more than the odd bee.
It's barley straw although other straws could be used, but barley is a good one. The feeder has to be stuffed full of staw from top to bottom so it's just not possible for the bees to drown. A bit floating on top is just not going to cut the mustard.
