The Oriental cockroach , measuring about 1 in (2.5 cm) in length at maturity. It is dark brown to black in color and has a glossy body. The female Oriental cockroach has a somewhat different appearance to the male, appearing to be wingless at casual glance but has two very short and useless wings just below its head. It has a wider body than the male. The male has long wings, which cover a majority of its body and are brown in color, and has a more narrow body. The odd male is capable of very short flights, ranging about 2 m (200 cm) to 3 m (300 cm). The female Oriental cockroach looks somewhat similar to the Florida woods cockroach, and may be mistaken for it.
The Oriental cockroach (also known as Waterbug) is a large species of cockroach that tends to travel somewhat more slowly than other species. They are often called “waterbugs” since they prefer dark, moist places. They can often be found around decaying organic matter, and in sewers, drains, damp basements, porches, and other damp locations. They can be found outside in bushes, under leaf groundcover, under mulch, and around other damp places outdoors.
PEST CONTROLIn order to thrive, cockroaches need a place to hide.
Oriental cockroaches can be harder to get rid of than other roaches. Although adults can be fairly easily killed by the application of residual insecticide, the insecticides can get washed away, and two months later females can hatch new larvae.
