German Cockroaches

The German Cockroach (Blattella germanica) is primarily a nocturnal pest and favours warm, humid atmospheres, especially where temperatures are around 25° to 30° C.

The Key Facts About German Cockroaches

German Cockroaches (Blattella germanica) - Pest Solutions - Pest ControlIn the UK, these pest insects prefer heated buildings and are generally not found outside. In buildings, German Cockroaches will infest kitchens and bathrooms where they are found in dark, secluded spaces. These may include the area underneath your sink, within plumbing fixtures, behind appliances, cracks or crevices, cupboards, and in similar locations.

German Cockroach (Blattella germanica) will often gather in groups in favourable harbourages. That being said, it is not unusual to find German cockroaches throughout a building should a particularly serious infestation develop. As part of their survival instinct, the cockroaches will gradually move away from heavily infested areas to other parts of the building, further complicating the pest control process.

Mature German cockroaches measure around 12-15mm long, and are virtually always coloured either tan or light brown. If you look closely, you will see that they have two thin black or dark brown bands running just behind their heads. What makes a German cockroach infestation particularly difficult to deal with is the fact that this species is able to reproduce much faster, and in greater numbers, than any other type of cockroach. On average, each time a German cockroach breeds the female will then go on to lay around 40 eggs. She will then carry what is known as the “case” of eggs around with her until they hatch.

Before reaching maturity, German cockroaches are known as nymphs. These nymphs are smaller than the adult cockroaches and are darker in colour. In addition, they will have a light brown stripe which runs along their back. It takes nymphs between 40 and 120 days to mature into an adult cockroach and from this point on their lifespan is around 200 days. Throughout adulthood, the typical female German cockroach will spawn up to eight times.

German Cockroach (Blattella germanica): The Significance of Control

Many people are repulsed and disgusted merely by the sight of German Cockroaches.

However, they are also an important public health risk by contaminating food, surfaces and eating utensils. German Cockroaches are known to carry pathogens, such as Salmonella and E.Coli, which can result in human diseases, such as food poisoning or diarrhoea.

German Cockroaches (Blattella germanica) - Pest Solutions - Pest Prevention

German cockroaches are notoriously difficult to control. There are a number of different reasons for this, which on their own make such cockroaches a formidable pest. Together, though, they make control by homeowners next to impossible- hence the need for professional pest control to completely eradicate medium-to-large infestations. As relatively large insects, cockroaches have few natural predators in the wild. Inside buildings, though, the number of predators drops to zero, meaning they will continue to thrive until they have exhausted any food sources present. The fact that they reproduce so quickly and in such large numbers will cause an infestation to spread extremely rapidly, too, so even a handful of German cockroaches can quickly lead to a major problem. Lastly, cockroaches naturally seek out dark, secluded areas because they are sensitive to light, which means that you likely won’t notice the severity of an infestation until it is highly developed.

As omnivores, German cockroaches will eat anything they can find. However, they are particularly keen on objects that are high in starch, as well as meat. In rare occasions, they may eat paper or fabric is no superior food sources can be found. When significant numbers of German cockroaches gather together in the same place, they often produce a secretion which can lead to stains and foul smells.

It is not just the German cockroaches themselves that can cause issues, either. These pests leave behind a significant amount of debris, from their droppings and saliva to shed skin, and these can all trigger allergies such as asthma in a significant proportion of people. Children are particularly susceptible to these side-effects, so if a cockroach infestation develops in a building where children are present, it is all the more essential that you call in the pest control experts to get the issue under control as quickly as possible.
