Exterminatory → It is formed from "ex-" (meaning out of or away) and "terminare" (meaning to limit or end). The word describes the act of putting an end to something by driving it out or eliminating it.
Think of 'driving out' ('ex-') something to 'end' it ('terminare') — that's why exterminatory means to eliminate or put an end to something.
