Cockroaches have developed a notorious reputation, known as one of the most commonly feared insects on Earth. Their resilience and difficulty in elimination contribute to this fear. However, much of their persistence hinges on their environment. With effective treatment strategies, tackling severe infestations is possible. In this article, we’ll explore the four types of cockroaches found in the Pacific Northwest, their behaviors, and how you can prevent them from invading your home.

Cockroach Vocabulary

Understanding some key terms can help you better comprehend cockroaches:

  • Ootheca(e): The egg cases that cockroaches use to store their eggs.
  • Harborage: Any location that provides protection or nesting opportunities, such as piles of clutter.
  • Molt: The process by which cockroaches shed their exoskeleton to grow.
  • Nymph: An immature cockroach that has not reached adulthood.

General Information and Life Cycle

Cockroaches undergo simple metamorphosis, transitioning through three phases: egg, nymph, and adult. This allows for overlapping generations, making it possible to find cockroaches in various life stages at any given time.

In Washington, cockroaches are primarily indoor pests. A persistent outdoor infestation usually indicates a severe indoor problem, making exterior treatments rarely necessary.

Females deposit their eggs in containers called oothecae, with the number of eggs varying by species—from 16 to 48. Nymphs, which hatch looking similar to adults but smaller, go through several molts over a period of months before reaching maturity.

Remember the saying: “When there’s one, there’s a hundred.” Spotting a cockroach often signifies a broader infestation. Cockroaches are nocturnal, so seeing one during the day may indicate a lack of hiding places.

Fun Fact: Cockroaches can survive for over a week without a head!


German Cockroach

German Cockroaches are small, typically around ? inch long, and identifiable by two dark stripes on a pale brown body. While they have wings, they rarely fly and can live for up to a year under ideal conditions.

Females carry their light tan oothecae until just before the eggs hatch. A single female can produce up to 8 egg cases, making control difficult.

Commonly found in places where food is abundant, German Cockroaches tend to hide during the day and can congregate in areas like kitchens and behind appliances.


Brown Banded Cockroach

Similar in size to German Cockroaches, Brown Banded Cockroaches differ in that females have short wings that do not cover their abdomens, while males have longer wings and can fly.
