Cockroach infestations can start small but quickly become severe. Knowing the signs of an infestation can help you act fast and prevent a small problem from turning into a major health hazard.

Common Signs of a Cockroach Infestation

  • Droppings: Cockroach droppings resemble coffee grounds or pepper and are often found in kitchens, bathrooms, and cabinets.
  • Unpleasant Odor: A strong, musty odor can indicate a large cockroach population. This smell is often strongest in the areas where they hide.
  • Shed Skins: Cockroaches shed their exoskeletons as they grow, leaving behind small, shell-like pieces.
  • Egg Casings: Cockroach egg cases are dark and oval-shaped, often found in hidden areas.
  • Sightings: Seeing a cockroach during the day is a strong sign of an infestation, as it usually means the colony is large.

Why Early Action Matters

The longer you wait, the larger the infestation will grow. Acting quickly can save you from a more severe infestation, health risks, and property damage.
