Inspect the obvious areas: Start with common odor-producing areas such as trash cans, pet areas, and restrooms.
Check for hidden sources: Odors can originate from hidden sources like mold or mildew growth behind walls or under appliances.
Isolate the odor: By temporarily closing off rooms or sections of the house, you can narrow down the location of the odor.
Use a flashlight and mirror: Illuminate dark areas and use a mirror to inspect hard-to-reach spaces for signs of mold or leaks.
Biological odors: These odors are caused by bacteria or mold growth. They may have a musty or earthy smell.
Chemical odors: These odors are produced by cleaning products, paints, or other chemicals. They can be sharp or pungent.
Pet odors: Pet urine and feces can create strong odors that are difficult to eliminate.
