Cockroaches belong to the Blattaria family.  There are more than 3,500 identified species with an assumed undiscovered 5,000 more.

The German cockroach is the most common cockroach found in Oregon and Washington.  It’s about 5/8 inches long, brown and has two dark longitudinal stripes on its back. They are found in kitchens, bathrooms and other areas with easy access to water are found.  These cockroaches thrive in poor sanitation. They eat starchy, sugary foods and grease and meat.  When these foods are scarce, they feed on soap, glue and toothpaste. They have even been known to become cannibalistic, eating the wings and legs of each other. The average capsule holds 30-40 eggs. Females produce an average of five capsules in her lifetime. The average lifespan of a cockroach is 20-30 weeks.

How they affect us

Cockroaches produce an odorous secretion that affects the flavor of food.  Their bodies carry bacteria, protozoans and viruses.  The common diseases transmitted by these German cockroaches are food poisoning, dysentery, and diarrhea. Allergies caused by these cockroaches cause skin rashes, watery eyes, sneezing, nasal congestion and asthma.


A thorough inspection is necessary.  A survey is needed to determine the extent of the infestation. There are a few forms of chemical control used to exterminate cockroaches.  Baiting is common, as is insecticidal dusts.  Pesticides are effective but come with its own dangers.  Ask us which would be best for you.


Sanitation is the most important preventative measure.  Clean up food and do not leave dirty dishes out.  Store food items in sealed containers.  Keep lids tightly on garbage cans if left in the home overnight.  There are a few things structurally you can do as well. Caulk holes in walls where pipes enter and leave walls in the kitchen, bathroom and other areas.
