Cockroaches may become pests in homes, restaurants, hospitals,
warehouses, offices, and virtually any structure that has food
preparation or storage areas. They contaminate food and eating
utensils, destroy fabric and paper products, and impart stains and
unpleasant odors to anything they touch.
Cockroaches, which can come into contact with human excrement in sewers
and with pet droppings, may transmit bacteria that cause food poisoning
(Salmonella spp. and Shigella spp.). They are also believed to be
capable of transmitting disease-causing organisms such as
Staphylococcus spp., Streptococcus spp., hepatitis virus, and coliform
bacteria. They also have been implicated in the spread of typhoid and
dysentery. Some people, especially those with asthma, are sensitive to
the allergens produced by these cockroaches. However, a major concern
with cockroaches is that people are repulsed when they find cockroaches
in their homes and kitchens.
Cockroaches are medium-sized to large insects in the order Dictyoptera
(formerly Orthoptera). They are broad, flattened insects with long
antennae and a prominent pronotum. Some people confuse them with
beetles, but adult cockroaches have membranous wings and lack the
thick, hardened forewings or elytra of beetles. They are nocturnal and
run rapidly when disturbed. Immature cockroaches (nymphs) look like
adults, but are smaller and do not have wings.
There are three types of Cockroach in Cyprus: Americana, Germanica and Orientalis.
