Disease transmission

Feces, molts and traces of saliva can cause severe allergies, eczema and asthma in humans.

We must not neglect the psychological effect that the stressful situation can have on a family and fear for the health, especially of children. And rightly so; children, the elderly or the sick are all the more vulnerable to the risks of diseases transmitted by the presence of cockroaches.

Diseases that cockroaches can transmit:

  • Salmonellosis
  • Dysentery
  • Typhoid fever
  • Tuberculosis
  • Hepatitis
  • Parasitic diseases
  • Fungal infections
  • Gastroenteritis

Damage caused by cockroaches

Besides the risks of the diseases mentioned, cockroaches can also cause significant financial damage. By contaminating food you are forced to throw away and replace your entire food supply. All work surfaces in contact with food should be cleaned thoroughly. For more advice on the right reflexes to have when dealing with a cockroach infestation in house .

Psychological damage

In addition, we should not underestimate the psychological effect that the presence of cockroaches in house can cause. Cockroaches can cause stress and fear especially concerning the health of children. And rightly so, young children and old people are more susceptible to possible diseases that cockroaches carry.

Along with fear, shame also plays a role in domestic situations. Cockroaches in house are often associated with poor hygiene. In apartment buildings, cockroaches in house can quickly spread to neighboring apartments. In this case the lack of hygiene is not even the cause in most cases of the cockroach problem.


Cockroach lifestyle and reproduction

Cockroaches have succeeded throughout the 200 million years of their evolution to adapt to even extreme living conditions. This is partly because they reproduce extremely quickly, but also because the cockroach always lives in hiding.

Not so easy to avoid cockroaches at home

No matter the environment, they always manage to sneak into hiding places to avoid predators and human pest control treatments. A third reason for their rock-solid survival ability is that almost anything serves as a source of food for them and they are able to digest anything, even spoiled food, paper, or leather.

Cockroach lifestyle

Cockroaches prefer a warm and humid microclimate. Their nests and eggs are preferably installed in dry places, false ceilings, partition walls and behind ovens and refrigerators in kitchens. During the day they hide in all the cracks, holes and other nooks and crannies and seek to completely envelop their body which is facilitated by their flat appearance.

For its personal hygiene the cockroach uses its mouth parts to clean its limbs. It also cleans its long antennae which are made up of a hundred sensory cells which above all allow communication between individuals. Much of their sex life and movement is directed by odorous substances. The cockroach has a very strong smell and taste, which makes it possible to find food even in the dark. The antennas allow a good sense of direction even if the cockroach does not see much.

According to their behavioral pattern, cockroaches live in dense aggregates comprising individuals of all ages. They fear the light and therefore move mainly at night. 2 to 3 hours after sunset their activity is most intense.

The cockroach is an omnivore and can even attack its own species in times of famine. He needs very little food, crumbs in cupboards and countertops as well as leftovers in the dishwasher can be more than enough.

If given a choice, cockroaches have a preference for sugary foods. Water is essential for the survival of cockroaches. They absorb it indirectly through food or directly in sinks and condensation water on pipes.

The cockroach is one of the fastest insects. Some kinds reach a maximum speed of 130cm / sec. On average, a cockroach can travel 1km / h. In addition cockroaches are excellent climbers. Thanks to kinds of suction cups on the legs, cockroaches can climb vertically and overcome all obstacles, even with their heads upside down. All kinds of cockroaches, with the exception of oriental cockroaches, are able to hover from a great height towards the ground.

Reproduction in cockroaches

Reproduction of cockroaches can happen in different ways depending on the species. Usually warm temperatures and water are needed. Mating is caused by odorous substances emitted by the female to attract the male.

cockroaches reproduction cycle

  • For the cockroach / oriental cockroach the maturation of the eggs to the adult insect lasts at least half a year and therefore 4 times longer than the German cockroach. On average, the development of the oriental cockroach takes place over 3/4 to a year. The incubation time of eggs at a temperature of 30 ° C takes approximately 2 months. Development time is prolonged if temperatures drop. At 20 ° C maturation can take up to 3 months. After hatching begins the development of the adult cockroach. In males at 30 ° C this phase can last up to 5 months, in females almost 15 months. During the larval stage, oriental cockroaches can moult up to 10 molts. The female carries pouches with an average of fifteen eggs. Unlike the German cockroach, this pouch is directly laid. The oriental cockroach lives on average about 10 months. Females produce 8 pockets of eggs during their lifetime.
  • The cockroach / American cockroach is the largest species of cockroach. Its development cycle is, compared to other kinds of cockroaches, even more temperature dependent. Development from egg to adult cockroach takes about 24 to 28 weeks in the American cockroach. Within this time the female produces about 15 bags with an average of 14 eggs, which are laid directly after training and placed in safety in various hiding places. American cockroaches live an average of one year to 15 months. The larvae hatch 1.5 months to 2 months later. It goes through 8 moults before reaching the adult stage.
