Roaches, scientifically known as Blattodea, are among the Earth's most resilient and adaptable insects, with a fossil record dating back over 300 million years—predating dinosaurs. There are thousands of species worldwide, though only a small fraction are considered household pests, most notably the German and American cockroaches.

These insects are well-known for their incredible survival skills. They can endure extreme conditions, surviving for weeks without food and up to a week without a head, breathing through small openings in their body segments called spiracles. Their flattened, flexible exoskeletons allow them to squeeze into narrow cracks and crevices, making them notoriously difficult to eradicate once they infiltrate a structure.

As nocturnal scavengers, roaches feed on virtually any organic matter, including food scraps, paper, cardboard, and even glue. While they do not bite humans aggressively, their presence is a major public health concern. Roaches mechanically transmit harmful bacteria and pathogens, such as Salmonella and E. coli, by walking across unsanitary surfaces and then onto food preparation areas or utensils. Furthermore, their shed skins, droppings, and saliva contain potent allergens that can trigger asthma attacks and allergic reactions, particularly in children.

Effective control and prevention rely heavily on strict sanitation. This includes sealing entry points, eliminating moisture sources, storing food in airtight containers, and disposing of garbage regularly. Because they reproduce rapidly, addressing an infestation typically requires a combination of targeted baits, traps, and professional pest management strategies to break their lifecycle.
