Make bug (3,2)
I believe the answer is:
get to
I believe this clue is a double definition.
'make' is the first definition.
('get to' can be a synonym of 'make')
'bug' is the second definition.
(both can mean irritate)
(Other definitions for get to that I've seen before include "Eventually upset" , "Arrive at, reach" , "Annoy" .)
