Shrews are insectivores which means that they feed on things like beetles, crickets, spiders, and worms; they will also prey on small birds, mice, and even other shrews. Some species may also feed on seeds, nuts, and plant roots.
Around homes, they can be found living around woodpiles in areas that have gardens, are landscaped and near compost. They are drawn to these places because they are typically home to the things that they use as food sources.
Shrews usually aren’t a problem inside of homes but do find themselves indoors from time to time. If they do get into a home, they should be eliminated quickly to stop them from contaminating your home and food sources with their urine and feces. Shrews should be controlled on properties because they are very aggressive and will attack small animals like birds and chipmunks at bird feeders, and may even attack small pets.
