Urban areas in the United States (U.S. Geological Survey, 1986) shown superimposed on the relative hazard of subterranean termite infestations (Beal and others, 1994).

[For urban areas to be visible on the map, the 100-m resolution urban areas were generalized to the 3-km resolution; only those 3-km grid cells consisting of at least 10 percent urban land use are colored on the map. km, kilometer; m, meter]
