Since mice are mostly active at night, it can be difficult to know for sure if you have them. There are telltale signs to look for, for example, evidence of gnawing. Mice will also chew on most anything, plasterboard, wood, vinyl siding and fiberboard.

They’ve also been known to chew on electrical wires in attics, causing fires. They will chew the edges of an opening to make it larger so they can get into tight spaces. If a mouse can find an edge or corner that it can bite with its teeth, it can gnaw an opening big enough to get the rest of its body through.

The oils in a mouse’s fur leave dark, greasy smudge marks where it brushes against walls. If you find mouse holes or the openings they are using to get into spaces, you will find that the holes are edged with dark rub marks from repeated use.

You may also hear scratching or scrambling noises in attics, wall voids, under cabinets or in other areas where mice are nesting. You may find a sign of mice in very dusty areas like crawl spaces or garage floors. Look for mouse footprints along with tail drag marks.
