The answer to 'termite scratching sounds' is that termite scratching is a common sign of an active termite infestation. Termites make audible scratching or clicking sounds as they move through the wood and build their nests. This is caused by their mandibles (jaws) scraping against the wood as they feed.
If you hear these faint, rustling sounds coming from your walls, floors, or ceilings, it's a good indication that you may have a termite problem. Other signs of termites include mud tubes, wood damage, and discarded wings. While some DIY treatments are possible, it's best to have a professional pest control expert inspect and treat the infestation to ensure it is fully eliminated.
