These unique organisms, otherwise consider pests themselves, would bear dire biological implications were they to disappear. Just think of nature´s work of replacing spiders with other predators, and humans trying to deal with an 800 million tons surplus of crawling insects including roaches, flies, and other invertebrates part of which would show up in homes uninvited.
