Shrews - Control Options
Traps, rodenticides, repellents and prevention are all options for controlling shrews.
Traps
Small infestations of shrews can be eliminated using expanded trigger mousetraps.
Shrews are only occasional visitors in homes. Indoors, traps can be placed along walls as would be done for the House Mouse. Outside, traps can be placed at the beginning of the runways a couple of inches from the burrows beneath natural cover. Traps can also be placed directly in the runways in the turf. For traps that are placed beneath cover, meat provides an enticing treat to shrews.
You should never try to capture or touch a shrew. They are aggressive, high-tempered little animals with sharp teeth. Some are even equipped with a toxin in their saliva.
Extreme caution should be taken in any shrew control methods.

Prevention
Shrews can be kept out of buildings via good rodent proofing techniques. Close mowing and brush removal will reduce the severity of shrew infestations.
To protect young trees during the winter, use a 12-inch tall fence made of hardware cloth buried 3 inches into the ground to create a shrew barrier.
