Who might bug you? (3)

I believe the answer is:

spy

(Other definitions for spy that I've seen before include "One who collects secret information as for government" , "Person who secretly collects information as for government" , "Discover" , "Undercover agent" , "Spot" .)

I've seen this clue in The New York Times.
