Natural Habitat

Damp, cool environments such as sewers, basements, crawl spaces, and under mulch or leaf litter; often referred to as water bugs.

Diet & Feeding

Omnivorous scavengers that feed on decaying organic matter, starchy foods, and proteins; they are particularly attracted to garbage and sewage.

Behavior Patterns

Primarily nocturnal insects that move slowly compared to other cockroach species; they cannot fly and are often found at ground level or in subterranean areas. Their life cycle includes egg (ootheca), nymph, and adult stages.

Risks & Benefits

Potential risks include the mechanical transmission of pathogens such as E. coli and Salmonella, and they can trigger allergies or asthma in humans. They provide a minor ecosystem benefit by recycling decaying organic matter in nature.
