The Biology of Cockroaches

Cockroaches are some of the most resilient creatures on the planet. They are members of the order Blattodea and are characterized by their flat, oval-shaped bodies, long antennae, and six legs. There are over 4,500 species of cockroaches worldwide, with the most common being the German, American, and Oriental cockroach. They are omnivores, feeding on everything from human food to decaying matter.

The Life Cycle of Cockroaches

Cockroaches undergo incomplete metamorphosis, which means that the nymphs resemble adult cockroaches but lack wings. The female cockroach lays eggs in an ootheca, a protective case that can hold up to 50 eggs. Once the eggs hatch, the nymphs emerge and molt several times before reaching adulthood. The entire life cycle can take anywhere from a few months to a year, depending on the species.

Cockroaches are a common problem in Spain, especially in urban areas with high population densities. They thrive in warm, humid environments, making Spain’s Mediterranean climate an ideal habitat for them.

They can enter homes through small cracks and crevices, and once inside, they can quickly infest entire buildings.
