Capable of being completely destroyed, eliminated, or wiped out.
From Latin exterminare (ex- 'out' + terminare 'to end or bound'). The suffix -able means 'capable of,' making this word mean 'capable of being exterminated.'
Pest control experts use the term 'exterminable infestation' to describe bug problems that can actually be solved—as opposed to the really stubborn ones that never quite go away!
