ASIAN ROACH (Blattella asahinai)
Actual body size 1/2”
The Asian Cockroach first appeared in Florida in 1986, and was thought to be the German
Cockroach. The only noticeable difference is that the Asian Cockroach has longer and
narrower wings. It has spread throughout the central and southern parts of the state. They
prefer outdoor locations, and large populations will develop in mulched or composted landscape
areas. They are strong fliers, and will often make their way into structures.

Asian Cockroaches will be found in lawns, and readily take to flight when disturbed. They also
are seen flying at dusk. They are attracted to lights and light-colored surfaces. They will eat
practically any organic matter, and can spread disease.
