Vermin in a crate (3)

I believe the answer is:

rat

'vermin' is the definition.
(I've seen this in other clues)

'in a crate' is the wordplay.
'in' indicates the answer is hidden within the clue.
'RAT' is hidden in the letters of 'crate'.

(Other definitions for rat that I've seen before include "Destructive rodent" , "Unpleasant character" , "Rodent; informer (colloq.)" , "Rodent pest" , "One deserting sinking ship" .)

I've seen this clue in The Mirror.
