However, a few kinds of roaches are well-adapted to indoor life and have been widely spread by humans, such as the German cockroach, Oriental cockroach and American cockroach. Essentially, all regional species have colonies below ground. Only the winged reproductive stages leave the colony. Termites are capable of digesting cellulose, often through the aid of protozoa in their digestive system. They overwinter as adults and eggs are produced in early winter.
Females stay with the eggs and young nymphs for the early part of their lives.
During the day, earwigs like to hide in dark, moist areas, which causes them to get into things. They can pinch with their mouthparts, but the cerci are weak and cannot produce a painful pinch. Because of the many similarities in appearance and habit, these two groups now are usually combined into the lice, order Phthiraptera. Some suck blood, others chew. The sucking lice suck blood from mammals and include such pests as the head louse and hog louse.
