Indoor environments, particularly in warm, humid areas with food access like kitchens, bathrooms, and laundry rooms.

Diet & Feeding

Omnivorous scavenger that consumes almost anything including human food scraps, grease, glue, toothpaste, and soap.

Behavior Patterns

Primarily nocturnal and highly social. They reproduce rapidly, with females carrying egg cases (oothecae) until just before hatching. They prefer tight crevices due to their thigmotactic nature.

Risks & Benefits

Significant indoor pest and health risk. They can carry pathogens including Salmonella and E. coli, and their shed skins and droppings are major triggers for asthma and allergies. There are no known benefits in a household setting.
