Two main species in Britain; the Oriental cockroach and the German cockroach.
These are gregarious insects and are well adapted to coexist with man. They are mainly nocturnal and spend the day sheltering in cracks and crevices around areas close to the food source from where they will emerge at night to scavenge and feed. They are proven vectors for disease transmission and are regarded as a serious public health pest.
It is highly unlikely that an amateur would be able to clear an infestation of these difficult to control insects and professional help will always be required. Hillbans Pest Control can provide eradication programmes incorporating the most up to date formulations and active ingredients.
