Cockroach (Ootheca/Egg Case)
Scientific Name: Blattaria (family varies, likely Blattella germanica or Periplaneta americana)
Order & Family: Order: Blattodea; Family: Blattellidae or Blattidae
Size: 5mm to 10mm in length
Natural Habitat
Warm, humid environments; commonly found in kitchens, bathrooms, basements, and behind appliances in residential and commercial buildings.
Diet & Feeding
The ootheca itself does not eat; it contains developing embryos. Once hatched, nymphs are scavengers that eat organic matter, crumbs, and starchy materials.
Behavior Patterns
The female carries the ootheca or deposits it in a secure, dark location. This protective casing provides a moisture-rich environment for 10 to 50 embryos until they are ready to hatch.
Risks & Benefits
High risk of pest infestation; cockroaches can carry bacteria such as Salmonella and E. coli, and their cast skins or droppings can trigger allergies and asthma.
