In general, shrews are terrestrial creatures that forage for seeds, insects, nuts, worms, and a variety of other foods in leaf litter and dense vegetation, but some specialise in climbing trees, living underground, living under snow, or even hunting in water.

Are shrews good or bad?

The little rodent-like critters aren't pretty, but shrews in the garden are generally beneficial. In fact, shrews are important members of the ecosystem and getting rid of them isn't always a good idea. Shrew damage is usually limited and generally consists of holes they may dig in search of insects.

What are shrews known for?

Echolocation: Some species of shrews are the only known terrestrial mammals with the ability to echolocate. Unlike bats and some aquatic animals that use echolocation to locate food, shrews are believed to only use this ability to get a sense of their territory.
