Asian Cockroaches

Pest Description

What is an Asian cockroach?
The Asian cockroach, Blattella asahinai (Mizukubo), is a little less than ¾” long when it is full-grown. It is a tan-colored roach with two dark stripes that run the length of its body. Asian cockroaches reproduce quickly. There have been reports of Asian cockroach populations as high as 250,000 insects per acre.

Since Asian cockroaches can occur in great numbers, a fairly large amount of bait might be needed. The bait will have to be re-applied from time to time because more roaches will fly into the yard. Many homeowners find it more convenient to rely on pest control professionals to control the Asian cockroach.


Why Should I Care?
Cockroaches have been reported to spread at least 33 kinds of bacteria, six kinds of parasitic worms, and at least seven other kinds of human pathogens. They can pick up germs on the spines of their legs and bodies as they crawl through decaying matter or sewage and then carry these into food or onto food surfaces. Germs that cockroaches eat from decaying matter or sewage are protected while in their bodies and may remain infective for several weeks longer than if they had been exposed to cleaning agents, rinse water, or just sunlight and air. Recent medical studies have shown that cockroach allergens cause lots of allergic reactions in inner city children. They were even shown to cause asthma in children. These allergens build up in deposits of droppings, secretions, cast skins, and dead bodies of roaches.
