Shrew

Shrews are among the world’s smallest mammals. Worldwide, there are over 250 species recognized, with over 30 species identified in the United States.

Fast Facts

Color Usually gray to black in color.
Size 3-4" long with a 4" tail.
Appearance Appearing similar to mice, shrew have a pointed snout and tiny eyes.

Diet 

Shrews primarily feed on insects, earthworms, slugs and spiders and will also feed on small animals, seeds, roots and other vegetables matter. Because of their small size, shrews lose body heat rapidly. In order to maintain a constant body temperature, they have a high metabolic rate and consume food every three to four hours. In a 24-hour period, some species of shrews will consume three times their body weight.

Habitat

A shrew's habitat depends on the species, but they are typically near structures, occasionally invading buildings. Often reusing tunnels made by moles and voles, they live in gardens and wooded areas where food supplies are abundant.

Life Cycle

Since a shrew’s territory does not require a lot of space, up to 80 shrews can all live within a single acre. Even though shrews are very territorial, they will intermix only to mate. Shrews breed from May through October, and a female produces at least two litters (21 day gestation period) during this time, each having from 4–10 young. The young grow extremely quickly and are independent at one month old. Typically shrews are born, live and die withing a year, but some may live just under two years.

Damage

Shrews do not have a considerable negative impact on humans and go about their lives unnoticed by most people. They occasionally become a nuisance when they live in close proximity to humans because of their aggressive nature. Shrews occasionally fall into window wells, attack pets, feed on stored foods, contaminate stored foods with feces and urine and bite humans when improperly handled.

Shrew Control

Due to their hostile nature and ability to move fast, shrews are difficult to get rid of. Contacting a pest control professional is the ideal way to resolve a shrew problem. Batzner Service Specialists are highly trained to conduct a thorough inspection to find evidence of shrews and determine the proper course of action to eliminate the problem.

Regular inspections of your home by a pest control professional throughout the year is the best method to identify and prevent any issues with shrews or other pests. The BAN System provides regularly scheduled preventive services every quarter.
