1. Take Note of the Details
Perhaps the first thing you should do when someone notices a mouse is to note where it was located. Did someone see feces? Did someone hear scurrying? Did an actual mouse run across a floor or into a crack in the wall? These are all important things to even just mentally take note of so you can work toward getting rid of the problem.2.

3. Look for Areas To Improve
You can do various tasks to improve your office so mice won't be enticed to take up residence there. Some prevention tips include:- Keeping the office clean - Even leaving a full garbage overnight could lure a mouse into the office in hopes of finding food inside. Keep your office clean using a rotating cleaning checklist that all employees must be a part of.
- Requiring food to be eaten in the kitchen - Everyone wants a snack at some point during the workday, but if you're trying to prevent a mouse infestation, you might want to require that all food be consumed in the kitchen or break room.
- Sealing all food items - Even when the food is kept in the kitchen or break room, it should be sealed in durable plastic containers with lids that screw on.
