Habitat:

• The Oriental cockroach prefers high temperatures but can also survive temperatures as low as -10°C. They are most often found behind furniture, in cavities, or in basements, near heating pipes and hot water lines. The Oriental cockroach is a common infestation in restaurants, kitchens, hotels, and hospitals. It produces three different pheromones:
• Sex pheromone: In females ready to mate, for reproduction.
• Aggregation pheromone: Present in the feces of the Oriental cockroach for signaling shared hiding places.
• Dispersion pheromone: antagonist of the aggregation pheromone, leads to the spread of a population if there are too many individuals.

Nutrition:

• Omnivore: This makes the Oriental cockroach an adaptable pest.

Behave:

• Social: Lives in groups.
• Nocturnal: The Oriental cockroach is strictly nocturnal and spends most of the day in hiding. Despite an infestation, sightings are very rare; a large population could develop without anyone noticing.

Driven:

• Damage: Can contaminate supplies and living spaces through the transport of bacteria, germs, fungi, and viruses.
• Allergy: The Oriental cockroach can be a cause of allergies such as asthma and hay fever in infants, children, and adolescents. Children who grow up in a contaminated environment are more likely to develop asthma or hay fever.

Disease transmission:

• It carries various bacteria, fungi, protozoa, and viruses. Furthermore, the likelihood of children developing allergies increases if they grow up in a contaminated area.
