Cockroach egg case (ootheca), likely American cockroach

Warm, damp, sheltered places such as drains, basements, sewers, utility areas, and building voids.

Adults are omnivorous scavengers that consume food scraps, starches, grease, paper, and organic debris. The pictured object is an egg case and does not feed.

Females produce ridged, dark-brown oothecae containing multiple eggs and deposit or glue them in protected sites. Cockroaches are mainly nocturnal and hide during daylight.

They can mechanically spread bacteria, contaminate food, and contribute to allergy or asthma symptoms. They provide limited scavenging and nutrient-recycling benefits but are generally unwanted indoors.
