Like many desert animals, the Desert Shrew can exist solely on the water obtained from its food, usually the soft inner parts of larger insects. Young Desert Shrews are able to fend for themselves by the time they are 40 days old. The most common predators of this species are owls. Little is known about breeding habits; apparently breeds throughout warmer months, probably bearing litters of 3-5 young.
