Cockroaches

CochroachCockroaches are believed to be over 300 million years old and are thought to have originated in the tropical and sub-tropical areas of Africa.

Worldwide there are over 3000 species of cockroaches however only half a dozen have attained the status of a pest species. The remaining non-pest species live in decaying plant material, dark damp areas such as caves, and beneath the bark of rotting trees.

The omnivorous appetite of cockroaches makes any unprotected food susceptible to cockroach infestation and contamination. Their indiscriminate feeding sources in such areas as sewers, drains and garbage areas bring them in contact with disease organisms including salmonella and other organisms associated with dysentery, typhoid, hepatitis and tuberculosis.

Cockroaches are nocturnal creatures and are seldom seen during the day time, however, in areas where there are heavy infestations, sightings of cockroaches may become more common. It is generally accepted that for every cockroach seen there are at least a further ten that are hidden away in out of sight areas. Common harbourage areas include cracks and crevices, dishwashers, electrical motors and switches, ovens and almost any warm, moist areas where food is available.

Tell tale signs indicating cockroach activity include the presence of egg cases, regurgitation marks, faeces, odour and cast-off nymphal skins.

Infestation occurs when cockroaches are carried into premises on raw materials or packaging or gain entry to the premises through drain covers, ventilation openings and under doors.

The female cockroach enclose their eggs in purse-shaped egg cases which they deposit or glue onto a surface prior to the eggs hatching. They are prolific breeders with the most common of the pest species, the German cockroach, being capable of producing 20,000 offspring within a twelve month period. Female cockroaches also have the ability to produce young without mating. This is referred to as parthenogenesis.
