Cockroach egg case (Ootheca)

Warm, dark, damp areas such as basements, kitchens, sewers, and wall voids

Cockroaches are omnivorous scavengers; the ootheca serves as protection for embryos during development

The female carries the egg case for a period before depositing it in a protected, humid crevice to hatch

No direct risk from the case itself, but presence indicates an infestation that can spread bacteria, allergens, and pathogens
