Natural Habitat

Dark, damp, cool areas such as basements, crawl spaces, sewers, and under leaf litter or mulch outside.

Diet & Feeding

Scavenger that feeds on decaying organic matter, garbage, and starchy foods; often referred to as a water bug because it prefers damp environments.

Behavior Patterns

Nocturnal and relatively slow-moving compared to other roaches. Unlike German cockroaches, they are not adept climbers of smooth vertical surfaces and prefer to stay at ground level.

Risks & Benefits

Risks include the spread of bacteria (like E. coli and Salmonella) and allergens that can trigger asthma. They do not provide significant benefits in indoor environments and are considered a major pest.
