Rural Gardening: Sudden Die Off, 1 by pawny

It is just tragic. My friends hive is dying at an alarming rate. Just this morning a few, but now they are dying by the hundreds. They seem very disoriented and some are flying into the window of the house.

Does anyone know what could cause this? Would some insecticide do this? Is there a way to have the bees tested so we can try and avoid this at a later date?

any help would be much appreciated.

thank you.
