The American cockroach (Periplaneta americana) is a large reddish-brown species, typically 3–5 cm long, that thrives in warm, humid places such as kitchens, basements, and sewers.They can contaminate food and surfaces with bacteria such as Salmonella and E. coli, while their droppings and secretions may trigger allergies and worsen asthma.Although unwanted indoors, they help decompose organic matter in nature, contributing to nutrient recycling and the ecosystem.
To control them, keep areas clean and dry, seal cracks and entry points, and contact a pest-control professional if the infestation becomes severe.
