The answer to 'pest scratching sounds' is that common causes include rodents like mice or rats, insects like woodworms, or other pests nesting or moving around in your walls, floors, or attic. Symptoms include intermittent scratching, scurrying, or gnawing noises, especially at night. Solutions depend on the specific pest, but may involve sealing entry points, setting traps, or applying pesticides.
For minor infestations, some DIY pest control methods like traps or repellents may work. However, for more serious or recurring issues, it's best to call a professional pest control technician. They can properly identify the pest, determine the extent of the problem, and safely apply the right treatments to eliminate the infestation.
