12/10/2025

1. Droppings & Debris

  • Rodents: Small, dark pellets near food, cabinets, or baseboards
  • Cockroaches: Coffee-ground-like specks or smear marks
  • Insects: Shed skins, wings, or egg casings in corners or under furniture

2. Strange Odors

  • Musty, oily smells can signal roaches
  • Ammonia-like scent may point to rats or mice
  • Sweet or sour odors could indicate decaying pests or nests

3. Structural Damage

  • Gnaw marks on wires, furniture, or insulation
  • Holes in walls, floors, or clothing (especially wool)
  • Crumbling wood or dry watt - possible termite activity

4. Nesting Materials

  • Shredded paper, insualtion, fabric, or cardboard in hidden areas
  • Found in attics, garages, behind appliances, or under sinks

5. Live or Dead Pests

  • Seeing pests during the day (especially nocturnal ones) suggests a heavy infestation
  • Accumulation of dead insects in basements or window sills is a red flag

6. Unusual Sounds

  • Scratching, scurrying, or squeaking in walls or ceilings—especially at night
  • Buzzing or fluttering from hidden corners

7. Grease Trails & Smudge Marks

  • Rodents often leave greasy paths along walls or baseboards
  • These marks can reveal their travel routes and nesting zones
