Common Culprits
Many things cause wall dust. Old paint can flake. Plaster can crumble. Drywall can wear down. Even wallpaper adhesives can degrade. These materials become tiny bits. These bits then turn into dust.
Home renovations are a big cause. Drilling or sanding creates dust. This dust can settle on walls. It can also come from the walls themselves. Think about wear and tear. Foot traffic can vibrate walls. This loosens particles. Even changes in humidity play a role. They can cause materials to expand and contract.
