The Asian Cockroach (Blattella asahinai)

Blattella asahinai, the asian cockroach, was first introduced to the United States in 1986.[1] Usually mixed up with the german cockroach, the asian cockroach has been known to invade homes from the outside by flying, whereas the german cockroaches can’t fly. If within a home they can infest at high rates and therefore many consider the asian roach to be a pest.

When they find a location that meets their needs they usually stay. Reports of 30,000 to 250,000 of this type of roach per acre in prime locations have been proven over time and therefore homes should be protected from them.[2] They populate in larger numbers during the summer and infestations breakout heavy during this season.


They foods that contain protein and starches, and they love greasy foods as well. When things are rough and food is hard to find, they sometimes turn cannibalistic and eat each other. They eat what most leave as crumbs underneath tables in homes.
