Eaves droppers? (7)
I believe the answer is:
icicles
'eaves droppers?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for icicles that I've seen before include "Frozen stalactites" , "Frozen drips" , "Pendent spears of frozen water (7)" , "Hanging spikes of frozen water" , "Frozen pendants" .)
