Scrounger's location beyond usual area (8)
I believe the answer is:
parasite
'scrounger's' is the definition.
(thesaurus)
'location beyond usual area' is the wordplay.
'location' becomes 'site' (site is a kind of location).
'beyond' means one lot of letters go next to another.
'usual' becomes 'par'.
'area' becomes 'a' (maths abbreviation).
'par'+'a'='para'
'site' put after 'para' is 'PARASITE'.
(Other definitions for parasite that I've seen before include "It depends on the host" , "Creature that lives off others" , "Say mistletoe" , "Animal that feeds off another" , "one who thrives on (or off) another" .)
