Biology:
Not such a prolific breeder as the German cockroach, the female usually deposits her egg case within about 30 hours after it is formed. It is either dropped or glued to something in a warm protected area close to a food source. Development time is dependent upon temperature but it takes a male 575 and a female 602 days on average at room temperature.

Habits:
In many areas this cockroach can survive quite well outside but does live mostly inside. They are found many of the times in cellars, voids and on first floors and at time s higher in buildings as they use the water pipes to climb. They feed on all types of food and decaying organic matter. They are despised because of their strong smell of cockroaches and because they feed on dirt and bad Hygiene.

Reasons for Control:
Prevention of disease, loss of goodwill, bad hygiene, damages to goods and property, to comply with UK Legislation.
