Pets turn out to be vermin (4)

Ross

I believe the answer is:

pest

'vermin' is the definition.

'pets turn out' is the wordplay.
'turn out' indicates an anagram.
'pets' is an anagram of 'PEST'.

'to be' acts as a link.

(Other definitions for pest that I've seen before include "Destructive insect or other animal" , "Troublesome man or animal" , "Menace" , "Troublesome person" , "Nuisance; half a European capital" .)

I've seen this clue in The Mirror.
