The answer to 'cockroach scratching sounds' is that the noises are likely caused by cockroaches moving and crawling around inside your home. Cockroaches make a variety of sounds, including scratching, rustling, and clicking noises as they move through walls, cabinets, and other hiding places. These sounds can be a sign of a cockroach infestation and should be addressed promptly.
If you're hearing consistent scratching or other noises that you suspect are from cockroaches, it's important to take action. Start by inspecting your home for signs of an infestation, such as droppings, egg casings, or live cockroaches. You can try some DIY pest control methods like using bait traps or applying insecticide sprays. However, if the problem persists or you have a large-scale infestation, it's best to call in a professional pest control technician who can properly identify and treat the issue.
