If you have ever lived in an apartment or rented a home, you have likely encountered the German cockroach. It is the most common cockroach found in homes, apartments, and restaurants.


  • Brown with 2 longitudinal stripes running down the thorax
  • 1/2 to 5/8 inches long


  • Cosmopolitian in distribution and will live anywhere humans build heated structures
  • Usually found in kitchens in secluded areas
  • Behind and under appliances
  • In cracks and crevices behind backslashes
  • At counter edges
  • Behind and under cabinets
  • In void areas around plumbing,
  • Backs of drawer wells
  • Will infest warm areas around appliance motors such as refrigerators and dishwashers


  • Will invade your home and leave fecal matter and other debris in and around food and food preparation areas
  • Can enter homes when boxes or products are shipped moved from one location to another
  • Reproduces at a high rate, completing a life cycle in 30 to 45 days
  • Produces 30-48 eggs at a time
  • Can generate 3 to 4 egg cases in a lifetime
  • Difficult to eradicate because they can infest so many areas and can be very difficult to contact with an insecticide


Contact a professional pest control company if you think German cockroaches have taken up residence in your home. Trained personnel know where to look for harborage sites and what products to apply to achieve fast and effective results. It is much easier to eliminate a German cockroach problem when it is newly established and small, rather than when the population has time to build.

  • Most commonly treated inside a home with baits, sprays, or an aerosol product
  • Baits are generally preferred
    • Have little or no odor
    • Roaches disperse the bait back into their refuge sites when they ingest it
    • Most have a secondary and even a tertiary killing effect, meaning roaches that die in the harborage site from a bait are cannibalized by their fellows, causing additional mortality
    • Sprays are applied to surfaces that roaches crawl across or into harborage areas
    • Contact poisons that persist for up to one month, depending on the product and the location where it is applied
    • Often mixed with insect growth regulators (IGR) will reduce or eliminate egg production and cause mortality in immature forms of the German cockroach
    • Aerosols are referred to as crach and crevice treatments
    • Forces roaches out of their harborage sites with a product that excite their nervous system (flushing agent)
    • Then sprayed directly with a contact product
    • Residual aerosols may be applied into harborage areas and onto surfaces where roaches crawl in the same manner as sprays
    • Commonly sold as over the counter remedies for homeowners, but typically has a short life span
