Cockroaches, in contrast, are fast crawlers.

Movement & Habitat

Water bugs are strong swimmers. They live in natural water sources and are sometimes drawn to artificial lights at night, which is why they might be found under porch lamps in summer.

Cockroaches, in contrast, are fast crawlers. They thrive in kitchens, bathrooms, basements, and anywhere with warmth, moisture, and food scraps. Unlike water bugs, they actively seek out human environments.

Behavior & Diet

Water bugs are predators. They use piercing mouthparts to inject enzymes into prey, essentially liquefying it before consumption.

Cockroaches are scavengers. They eat almost anything organic—food crumbs, paper, cardboard, soap, even hair. Their ability to survive on little sustenance is one reason they are so difficult to eliminate.
