Recognition of the most common pests in our local urban environment

Correct identification of pests is the first step toward effectively solving related problems. Below are descriptions of the most common pests and the differences among them.

German cockroach (Blattella germanica)

The German cockroach is a small insect that can measure up to 15 mm in length. It is light brown in color and often features two distinct dark stripes on the top of its body. It is very active at night and prefers warm, humid environments, such as kitchens and bathrooms. It is usually observed in kitchen cabinets, on walls (as it is a good climber), or on the kitchen counter.

Oriental cockroach (Blattaella orientalis)

The Oriental cockroach is larger than the German cockroach and can reach a length of up to 30 mm. Its body is dark brown or black. It is most commonly found in damp, dark areas, such as cellars, warehouses, and sewer pipes, and is typically seen on the ground.

Norway rat (Rattus norvegicus)

The Norway rat is relatively large; together with its tail, it can reach up to 40 cm in length. Its body is grayish-brown, with small ears and a relatively short tail compared to its body length. It is common in sewers, cellars, warehouses, and near buildings. It is an excellent swimmer and easily adapts to various conditions.

House mouse (Mus musculus)

The house mouse is a very common rodent and pest in human living spaces. An adult mouse, including its tail, measures between 13 and 18 cm and is gray in color. House mice are adept jumpers, climbers, and swimmers, and they are most active at night. They primarily feed on plant material, and their droppings are elongated, dark, and can be up to 3 mm long.
