German Cockroach Description
Adult German Cockroaches are smaller (about 5/8 inch long) and light brown in color. They have a thoracic shield behind the head which is marked with two black stripes. Younger nymphs are even smaller, wingless, and have a pale stripe running down the middle of its body. Nymphs have a darker color body as compared to adults.
This roaches life cycle is considered simple metamorphosis, which includes an egg, nymph, and adult. Pregnant females will produce an egg capsule (about 5/16 inch long) that is attached to the roach for up to a month before being dropped. The eggs usually hatch within a day or two of being dropped. Each egg capsule contains 30-40 eggs, that’s a lot of roaches being hatched! The nymphs that hatch from the eggs are less than 1/8 inch long and wingless, they become adults in 75-85 days. If the problem isn’t mitigated, there can be up to four generations per year.
German Cockroaches are mainly indoor species. A common way homes become infested is by bringing in materials such as grocery bags or boxes that have eggs attached to them. Bathrooms, kitchens, or other places that provide moisture, food, warmth, and shelter is where you’ll find these smaller roaches. They’ll search for food and water at night mainly, but you will see them running around in the day too. These roaches also hang out in kitchen cabinets, under/behind appliances, you might even find them living inside appliances.
From various points in their bodies American cockroaches, produce odorous secretions that can affect the flavor of various foods. When populations are high, these secretions may result in a characteristic odor in the general region of the infestation. Disease-producing organisms such as bacteria, protozoa, and viruses have been found in cockroach bodies. Different forms of food poisoning and dysentery appear to be the principal diseases transmitted by these cockroaches. These disease-causing organisms are carried on the legs and bodies of cockroaches, and are deposited on food and utensils as cockroaches forage. Cockroach excrement and cast skins also contain a number of allergens, to which many people exhibit allergic responses such as skin rashes, watery eyes, congestion of nasal passages, asthma, and sneezing.
