Western Wood Cockroach

The Western Wood Cockroach, Parcoblatta americana, is a native California cockroach that lives outdoors. It can be found under rocks, and in and under old logs. This roach will sometimes be found inside homes, but this occurrence is mostly accidental, as western wood roaches do not live and breed in homes, as do the common household cockroaches.

The male, shown below, is a strong flier and is often attracted by lights. The female is wingless.
