Masterful Instructions
Begin the pest activity audit by accessing the attic, crawlspace, and perimeter basement walls during a period of low ambient noise to identify localized scratching, scurrying, or chewing sounds that indicate active rodent or insect colonization; use a high-lumen flashlight held at a low angle to highlight tracks in the dust or depressions in the insulation that indicate frequently traveled runways; perform a fecal matter identification by examining the size, shape, and moisture content of any droppings found along the top plates or rim joists—noting that small, spindle-shaped droppings suggest mice or rats while larger, blunt-ended pellets may indicate raccoons or opossums; look specifically for sebum or grease marks which are dark, oily stains left on wooden framing where rodents squeeze through tight gaps; examine the underside of the roof deck for mud tubes or discarded wings which are definitive indicators of subterranean or drywood termite activity; inspect all localized nesting sites such as shredded insulation, chewed cardboard, or gathered fabric near heat-producing appliances or HVAC ducts; check for structural gnaw marks on electrical wiring jackets or plastic PEX plumbing lines which pose a significant fire and flood risk to the building envelope; finalize the audit by identifying all potential entry points larger than a quarter-inch and marking them for immediate exclusion with steel wool or heavy-duty hardware cloth.
If you find a hole and aren't sure if it's currently being used, perform a Flour Test; sprinkle a light dusting of flour or talcum powder around the opening—if you see fresh footprints in the white powder the next morning, you know exactly what is living in your walls and which direction they are traveling.
