How to Get Rid of Shrews
Taking preventive measures to "rodent-proof" your home can be the best way to get rid of a shrew problem before it starts. Fill holes and crevices that could serve as shrew entry points. Closely mowing your lawn and removing brush will eliminate favorite shrew habitats and cause them to move to another area. Cats are also proficient shrew catchers, so allowing your feline to roam across your property can reduce or eliminate an outdoor shrew problem.
If shrews are present inside your home, live trapping can be an effective control method. Choose a trap that's small enough to conform to the shrew's tiny size, and bait it with shrew favorites such as crisp bacon, peanut butter or hot dog slices. Be sure to place your trap in any area where you've noticed signs of shrew activity.
