Bunny annoys insects (4)
I believe the answer is:
bugs
I believe this clue is a triple definition!
'bunny' is the first definition.
(I've seen this in another clue)
'annoys' is the second definition.
(I've seen this in another clue)
'insects' is the third definition.
(bug is a kind of insect)
(Other definitions for bugs that I've seen before include "Program errors" , "Small crawling creatures or disease-germs" , "taps" , "Secret listening devices" , "Errors in computer programs" .)
