BIOLOGY OF GERMAN ROACH

The German cockroach is one of the most common roaches found in apartment houses, restaurants, and hotels. German cockroaches (eggs included), are brought in, usually on man's belongings, luggage, boxes, or packages. All it takes, is bringing in one egg capsule, six months later you could have an infestation.

Females produce one egg capsule every 3-4 weeks. Each capsule contains 25-45 eggs. The female will carry the egg capsule with her until it is ready to hatch. The young(nymphs) will be able to breed in as little as 36 days. Adult German roaches can live up to one year These roaches are mostly active at night .

If they are seen during the day, it is usually because their hiding places are overcrowded due to a large population or there is a shortage of food and water supply.

Any crack or crevice located near a source of food and/or water is prime harborage, and they spend about 75% of their time in such harborages. First instar nymphs require a crack of about 1/32" whereas, adults require a crack of about 3/16" in width.

Infestations are generally found in kitchens and bathrooms, but can inhabit other areas if there is a heavy population or you have run them into each other with the repellent effect of insecticides.
