The answer to 'pest scratching sounds' is that these sounds are typically caused by rodents, such as mice or rats, nesting or moving around in your home. Common symptoms include hearing scratching or scurrying noises, especially at night, as well as signs of chewed food or damage to your home's structure.
The best solution depends on the severity of the infestation. For minor issues, you may be able to handle it yourself with traps, sealing entry points, and removing food sources. However, for larger infestations or if the scratching sounds persist, it's best to call a professional pest control technician. They have the expertise and equipment to properly identify the pests and implement a comprehensive treatment plan to eliminate them safely and effectively.
