A cockroach is an insect of the order Blattodea, which also includes termites. About 30 cockroach species out of 4,600 are associated with human habitats. They are often evenly distributed throughout the home but it is more common to find them in warm, dry places with access to food. Their flattened bodies allow them to fit into tiny crevices–especially around kitchen cabinets and sinks–and to live in close proximity to humans without being noticed.
Cockroaches are generally considered pests because they can feed on almost anything, they can carry different kinds diseases through pathogenic bacteria that grow on their bodies, and their presence is aesthetically displeasing.
