However, you should hire a professional bed bug exterminator to eliminate large numbers of bed bugs.

Finding mouse droppings without seeing any mice is a common sign of an infestation because mice are nocturnal and skilled at hiding from humans. Droppings are often the first and most visible evidence of their presence. The location, quantity, and freshness of the droppings can help you determine where the mice are most active and how severe the infestation might be. Since mice are active at night and often travel through hidden pathways like inside walls, you may not see them directly. It's important to look for other signs of an infestation, such as gnaw marks, scratching sounds, or greasy trails along walls. If you find droppings, consider setting traps or contacting a professional exterminator to address the issue.
