Economic Importance for Humans: Negative
Deer mice consume seeds of valued forest trees, sometimes preventing regrowth. In addition, P. maniculatus can be destructive by raiding stored grains and other food supplies, gathering litter, and gnawing (Baker 1983). Finally, P. maniculatus is a host for strain of hantavirus called Sin Nombre virus (also called Four Corners or Muerto Canyon virus). This virus, which can be contracted by humans from deer mice, causes an often fatal disease termed hantavirus pulmonary syndrome (Rowe et al. 1995).
