  • Also known as waterbugs, Oriental cockroaches are non-flying insects with smooth, dark bodies and a tendency to live in damp areas.
  • Like most roaches, they feed on filth and can pose serious problems when they enter homes in large numbers to seek refuge from the outdoor environment.
  • Unlike many other species however, the Oriental cockroach can withstand freezing temperatures and is often encountered in homes year-round as a result.
  • In addition to spreading filth, the pests are notorious for emitting a distinct and unpleasant odor.


What Do Oriental Cockroaches Eat?

  • Decaying Starchy Food
    The Oriental cockroach diet largely consists of decaying organic matter like the remnants of starchy foods. Trash receptacles and discarded tin cans in particular serve as ideal places for the pest insects to find a suitable meal.
  • Water
    Without food, Oriental cockroaches can survive for a month as long as they have access to water. In the absence of water, however, the insects typically cannot live longer than two weeks.


  • Eggs
    Newborn Oriental cockroaches hatch from eggs and take about 1 1/2 years to reach adulthood.
  • Egg Production
    Females carry the eggs in a protective case for about 24 to 30 hours before depositing the specialized capsule close to a food source. At room temperature, Oriental cockroach eggs take about 2 months to hatch. During the adult lifespan, females each produce an average of eight egg capsules, which contain 16 eggs apiece.
  • Nymphs
    The newborn insects emerge as nymphs and molt between seven and ten times before fully maturing.
  • Adult Life Span
    Upon reaching adulthood, Oriental cockroaches typically live for up to six months.

Problems Caused by Oriental Cockroaches

  • Germs
    Because they tend to live in unsanitary environments and feed on filth, Oriental cockroaches have plenty of opportunities to spread germs and bacteria. The insects spread contaminants by passing through sewage or decaying matter and then crawling over food items, dishes and utensils and kitchen surfaces while foraging indoors.
  • Pathogens
    Specifically, the pests are known to spread the pathogens for

    • Food poisoning
    • Dysentery
    • Diarrhea
  • Odor
    Other problems caused by Oriental cockroaches include the odorous secretions the insects emit and the allergens contained in their excrement and molted skins.
  • Allergies
    For people with allergies, cockroach feces and discarded skins can cause reactions like nasal congestion, sneezing, watery eyes, asthma and a rash on the skin.


  • Moisture: Often found in moist or damp areas, such as basements and crawl spaces.
  • Spills: Known to congregate in large numbers around leaks, spills and unsealed food.
  • Ground Level: Tend to remain at the lower levels of buildings and rarely venture to upper floors.
  • Warmth: Prefer environments with temperatures ranging from 68 to 82 degrees Fahrenheit.

Signs of Infestation

Many of the problems caused by Oriental cockroaches can also serve as signs of infestation.

Prevention Tips

  • Cleanliness
    Maintaining a clean and sanitary home environment represents the best way to prevent Oriental cockroaches from invading.
  • Vaccuum
    This includes vacuuming and cleaning the house regularly, especially the kitchen.
  • Seal Entry Points
    Seal cracks and crevices and close the openings around utility pipes.
  • Moisture
    Ventilate damp areas, such as basements and crawl spaces, to stop moisture from accumulating helps make the home less attractive to Oriental cockroaches, as well.

Tips for Removal from Home

In the event of an Oriental cockroach infestation, the residents of the affected structure should first determine the extent of the problem by using sticky traps to catch a sampling of the insects.
