Roaches are oval, flat insects that vary in size depending on the species. The most common roach characteristics include the following.
Roaches have six long legs with pads that enable them to scale surfaces or walk on walls.
Male cockroaches are smaller than females, who carry the eggs. Male cockroaches of certain species, on the other hand, can possess wings.
Roach nymphs are paler in color and will molt several times before reaching maturity.
Cockroaches vary in appearance depending on their species: American cockroaches are large and reddish-brown in color. German roaches are nearly half the size of American roaches and are brown in color. Oriental roaches are nearly black in color and are also on the larger side.
