About Cockroaches and Termites: the wider group
Order-level background for Blattodea, the group containing Blattella germanica. Species-specific details appear above.
Group overview
Blattodea includes ~4,600 cockroach species and ~3,000 termite species. Only about 30 cockroach species are associated with human habitats - less than 1% of all species.
Ecological role of the group
Termites contribute ~40% of soil arthropod biomass globally, far exceeding ants at ~10%. Cockroaches are ancient insects dating back 320 million years and are critical decomposers in tropical forest ecosystems, recycling leaf litter and dead wood.
Economic and practical significance of the group
Termites cause $5-30 billion in damage to structures in the U.S. annually. They damage approximately 600,000 American homes each year, with average repair costs of $3,000-$17,000. A subterranean termite colony can consume one pound of wood per day.
