The answer to 'what causes cockroach' is cockroaches are attracted to warm, moist environments with access to food and water. They thrive in homes that provide these conditions, such as kitchens, bathrooms, and areas with clutter or moisture issues. Cockroaches can enter homes through cracks, crevices, and small openings, and they reproduce quickly, making them a common household pest.
Cockroaches are drawn to sources of food, water, and shelter, and they can spread bacteria, contaminate food, and trigger allergies or asthma in some people. Proper sanitation, sealing entry points, and targeted pest control measures are essential for managing cockroach infestations.
