Ordinary mouse snap traps, sold in most grocery and hardware stores, are effective in catching white-footed and deer mice. Bait traps with peanut butter, sunflower seed, or moistened rolled oats. For best results, use several traps even if only a single mouse is believed to be present. Set traps as you would for house mice: against walls, along likely travel routes, and behind objects. Automatic traps designed to live-capture several house mice in a single setting also are effective against white-footed and deer mice. They should be checked frequently to dispose of captured mice in an appropriate manner: euthanize them with carbon dioxide gas in a closed container, or release them alive into an appropriate location where they won’t cause future problems. For further details on trapping, see House Mice.
