Stop menace spreading and reimburse (10)
I believe the answer is:
compensate
'reimburse' is the definition.
(I've seen this before)
'stop menace spreading' is the wordplay.
'spreading' is an anagram indicator.
'stop'+'menace'='stopmenace'
'stopmenace' anagrammed gives 'COMPENSATE'.
'and' acts as a link.
(Other definitions for compensate that I've seen before include "Make good" , "Balance" , "attempt to limit damage" , "Make financial amends to" , "Reimburse" .)
