Densities, food habits, and physical condition of white‐footed mice (Peromyscus leucopus) were examined on 10 Dimilinr̀‐treated and 10 untreated areas in 1985 and 1986. Estimates of mouse density did not differ significantly ( p > 0.05) between treated and untreated areas. However, juvenile/adult female ratios on untreated areas were significantly higher ( p < 0.05) than those on treated areas. Mice on treated areas consumed less lepidopteran prey than did mice on untreated areas ( p < 0.05), but the total amount of food consumed per mouse did not differ significantly between treated and untreated areas ( p > 0.05); mice in treated areas apparently compensated for the loss of lepidopterans by using other food sources more heavily. Body measurements, weight, and fat content of mice did not differ ( p > 0.05) between treated and untreated areas.
