The municipality lies in the wooded Meulenwald hill range, southwest of Wittlich at an elevation of some 400 m above sea level.

The spelling for the placename changed very often: Dierscheid, Dierschet, Dischet, Dirscheit, Dierscheydt, Dierscheit, Dyrseit and Derseit.

[3] The German blazon reads: In Silber auf rotem Dreiberg, darin eine goldene Hirschstange, drei grüne Fichten mit goldenen Zapfen.

The three-knolled hill in the escutcheon’s base symbolizes the municipality's location in mountain heights in the Voreifel.

The tinctures argent and gules (silver and red) are a reference to the village's former allegiance to the Electorate of Trier.
