Limited containment of bug (4)

I believe the answer is:

mite

'bug' is the definition.
(thesaurus)

'limited containment of' is the wordplay.
'containment of' indicates a hidden word.
'MITE' is hidden in the letters of 'limited'.

(Other definitions for mite that I've seen before include "Child; a small amount" , "Very small creature or child" , "The widow's small offering" , "Tiny arachnid, person or amount of money" , "The widow's small donation" .)

I've seen this clue in The Guardian.
