Cockroaches are among the most common hygiene pests worldwide. The German cockroach (Blattella germanica) and the oriental cockroach (Blatta orientalis) are particularly common. They are nocturnal, light-shy, and prefer warm, humid areas such as kitchens, bathrooms, basements, and pantries.

Cockroaches are not only annoying but also a health hazard , as they can transmit bacteria, viruses, and mold spores. Their droppings, molting residue, and egg packets contaminate food and can trigger allergies.
