The typical habitat of this species consists of stunted montane scrub and ridge vegetation, which rarely exceeds 1.5 m in height. The species also occurs in mossy forest. Nepenthes murudensis has no known natural hybrids, although N. hurrelliana, N. lowii, N. muluensis and N. tentaculata also occur on the mountain. In 1996, John De Witte reported observing N. reinwardtiana on Mount Murud, but other authors have failed to find it on the mountain.
