House mice are small rodents that weight about one-half ounce. Though small, these rodents can do a lot of damage. Although perhaps most known for getting into food and chewing wires, mice are just as happy to chew a hole in your new leather couch. Fortunately, there are steps you can take to remove mice from your home and prevent them from chewing your couch.
Eliminate food sources. Mice are scavengers and will eat almost any food that is lying around. It is likely that the mouse exploring your couch is drawn to the area because of food. Vacuum up any crumbs on the couch (be sure to get under the cushions). In addition, wipe down any spills on the couch with a leather-safe household cleaner.
Place a multiple-capture mouse trap, available at most hardware stores, on the couch. Having a mouse trap on your couch isn't ideal, but it is the most effective way to capture the mouse that is gnawing on your couch. If you would prefer not to find a decapitated mouse on your couch, you can use a glue board (also available at hardware stores). Keep in mind that although there are rodenticides (poison baits) designed to kill mice, you should not place rodenticides in areas where you will be present. Rodenticides are toxic and can be dangerous if handled improperly, especially if ingested by children or pets.
Eliminate entrance points. To prevent mice from chewing on your couch, it helps to prevent mice from entering your home. Mice need only about one-fourth inch of space to enter your home. Seal cracks and openings, make sure windows are fitted tightly, and consider using weatherstripping.
Get a cat. It may not be an option for some, but it's hard to imagine a mouse continuing to chew a couch if there is a cat lounging there.
