Having survived multiple mass extinctions, cockroaches now comprise over 4,500 known species worldwide. Many have seamlessly adapted to human environments, becoming “uninvited neighbors” in nearly all human habitats.This article explores the biological resilience, evolutionary significance, and hidden threats posed by cockroaches in contemporary living. It examines their role as silent carriers of disease and allergens, while offering scientific insights and community-based strategies for control and prevention.
