The answer to 'why is my mouse odor' is that a mouse infestation in your home can often be detected by the distinct musky odor they produce. This odor is caused by the mice themselves, as well as their urine and droppings. Mice have scent glands that secrete this strong, unpleasant smell to mark their territory and communicate with other mice.
The mouse odor may be more noticeable in areas where they are nesting or feeding, such as in walls, cabinets, or under appliances. The smell can linger and be difficult to get rid of, even after the mice have been removed. Addressing a mouse problem promptly is important to minimize the odor and potential health risks they pose.
