Asian Cockroach

Blattella asahinai

Asian cockroaches thrive in shaded outdoor mulch, leaf litter, and grassy turf rather than hiding deep within indoor kitchens. Unlike their flightless domestic counterparts, adults take to the air readily at dusk, often fluttering directly toward porch lamps, lighted windows, and television screens. Females produce multiple egg cases containing dozens of embryos, maintaining dense outdoor populations throughout warm subtropical summers.
