A drain cover is primarily composed of a layer of eco-material paved on the drain cover. The eco-material is made by stirring wastes of irregular shapes (e.g., slag, glass fragments, ceramic or waste gravels) with an adhesive agent and fiber glass yarns. By paving the eco-material on drain holes of the drain cover, trashes and grits can be prevented from flowing into a drain to cause an imperfect draining and a clogging. The wastes after being stirred with the adhesive agent and the fiber glass yarns can prevent insects from crawling out of the drain holes, and can reduce a drifting of odor in the drain. In addition, the wastes of irregular shapes can also increase a slip-proof effect to the drain cover, such that a pedestrian will not be tripped by the drain holes, thereby increasing a safety of walking of the pedestrian.
