Bugs found in hair etc -- a bride's revolting (8)
I believe the answer is:
bacteria
'bugs' is the definition.
(I've seen this before)
'in hair etc a bride's revolting' is the wordplay.
'in' says the answer is hidden in the clue.
'revolting' says the letters should be written backwards.
'airetcab' can be found hidden inside 'hair etc a brides'.
'airetcab' in reverse letter order is 'BACTERIA'.
'found' acts as a link.
(Other definitions for bacteria that I've seen before include "Tiny causes of disease" , "Tiny organisms, may be good or bad" , "Cabaret I perform badly for the tiny organisms" , "Single-cell organisims" , "Microscopic organisms, can carry disease" .)
