This is the job description http://xxxnx.fun/cxvideoscim/ planetsuzy standard emily willis No species has a "right" to any resource. Nature is based on sustainable exploitation. It just happens that they evolved to harness blood as a resource. In any case, it would neither be right or wrong to eradicate this species. Personally, I find it humorous that such a small insect can get under everyones skin. (couldnt resist). I'd leave the species alone.
