Hearing scratching noises in your walls can be alarming, but experts warn against jumping to conclusions without sufficient evidence. According to the Centers for Disease Control and Prevention (CDC), it is essential to conduct a thorough inspection for physical signs of rodents, such as droppings, gnaw marks, and urine stains. These indicators are more reliable than sounds alone. Rodents typically use specific pathways for movement, often along edges and baseboards, making these areas critical for inspection. The CDC advises checking behind kitchen counters, around appliances, and in attics or crawl spaces for signs of infestation. To effectively manage potential rodent issues, homeowners should seal off entry points, secure food sources, and maintain cleanliness. This strategic approach helps mitigate risks associated with rodent contamination, as their droppings and urine can carry diseases. Ultimately, while scratching sounds may signal a problem, they should prompt a careful investigation rather than immediate panic.
