German Cockroaches

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.

German cockroaches are brown with 2 longitudinal stripes running down the thorax

1/2 to 5/8 inches long

German cockroaches 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

German cockroaches 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

German roaches are most commonly treated inside a home with baits, sprays, or an aerosol product (baits preferred)

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

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
