Small scamps (4)
I believe the answer is:
imps
'small scamps' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for imps that I've seen before include "Small devils or mischievous children" , "repairs (for a wing)" , "Mischievous fairies" , "Little mischievous devils" , "Mischievous spirits" .)
