Blame guy for disruption — pest! (5,3)

I believe the answer is:

mealy bug

'pest' is the definition.

'blame guy for disruption' is the wordplay.
'for disruption' indicates anagramming the letters.
'blame'+'guy'='blameguy'
'blameguy' is an anagram of 'MEALY-BUG'.

(Other definitions for mealy bug that I've seen before include "Scale insect" , "Sap-sucking insect" , "Hothouse pest" .)

I've seen this clue in The Guardian.
