How German Cockroaches Enter Your Home?

German cockroaches take over your kitchen once they are in your home. It is common for them to be brought home from shops in grocery bags, cardboard boxes, and packaging of various products.

If you are shifting furniture from your old home to your new one, there are chances of them being transferred through your furniture, electrical appliances, and other personal belongings. Once these pests come to a new location and find a favourable condition to live in, they reproduce in large numbers and increase their population quickly.

These cockroaches are small and have a tan or light brown colour. They have two distinct dark brown lines along the edge of their body and are known to grow between 13-16mm in length. Though these cockroaches are smaller than the other types, they are considered the fastest of all, making them difficult to detect.

The egg capsule of female cockroaches contains 30 – 48 eggs. These eggs are ready to hatch in a month; once ready, the females attach the capsule in a dark space to allow the young to emerge safely. The nymphs develop into adult cockroaches in six weeks to six months. Each female German Cockroach can produce up to 20,000 cockroaches annually.

Behaviour and Adaptations

The German Cockroach has adapted to a wide range of climates, making them one of the most common pests known. Their behaviour is often related to their need for shelter, food and water, as these are essential elements for the survival of the species. They move about in large groups and reproduce quickly when conditions are favourable.

As such, they prefer dark and humid places such as kitchens and bathrooms. Even though they avoid light exposure, when cornered they can be surprisingly fast runners and climbers! Knowing this helps us to better understand their behaviour and design better methods that can reduce or stop their presence in our homes and offices.

Dangers to Humans

German cockroaches can pick up germs on their leg spines as they crawl through decaying matter and transfer them to food and other common surfaces that humans touch often.

As a result, they can spread bacteria, parasitic worms, and human pathogens that may lead to disease transmission. Cockroaches also trigger allergies and asthma symptoms through saliva, droppings, and decomposing bodies.
