Genus Cryptocercus, also known as wood roaches or Cuban wood roaches, are insects that belong to the cockroach family. These roaches are found in the East Asia and North America regions, where they are known to infest and feed on rotting wood. Other synonyms for Genus Cryptocercus include Cryptocercus punctulatus, Cryptocercus darwini and Cryptocercus relictus. These synonyms all refer to the same species of wood roaches with varying characteristics. Although wood roaches play an important role in recycling wood in their natural environment, they can also be a nuisance when they infest human homes. They are attracted to moisture and need regular cleaning and maintenance to prevent an infestation.
