Shrews have been known to enter buildings. Rodent-proofing will exclude shrews from entering structures. Look along the foundation sill, pipes, eaves, attic screens and other places where gaps occur in the structure. Shrews have been found in attics so don’t forget to look along eaves.
Here are some ways to exclude shrews:
- Place hardware cloth of 1/4-inch (0.6-cm) mesh over potential entrances to exclude shrews. The pygmy shrew (Sorex hoyi) may require a smaller mesh (but this would be very uncommon).
- Coarse steel wool placed in small openings can also exclude shrews. Steel wool will rust; copper wool or netting will last longer.
- Exterior grade caulk can also be an excellent, more permanent choice.
- Keep vegetation and other potential hiding places away from the foundation to reduce the attractiveness of this area as habitat.
