Pest biology

The two main species of cockroach in Britain are the Oriental and German cockroach. The Oriental is dark brown and about 30mm long. The German is a light yellowish brown of about 12mm in length.

Cockroaches are generally found indoors, such as cellars, kitchens, bakeries and heating ducts. Cockroaches will often remain hidden during the day using cracks and crevices.

Problems they cause

Cockroaches are capable of carrying the organisms which cause food poisoning and many other bacteria. They will feed on almost anything, including refuse, faecal matter and food for human consumption. They also carry an unpleasant smell caused by their pheromones.

What you can do to help

Good hygiene and a thorough cleansing of your premises is essential in preventing infestations. Pay particular attention to removing food and water sources and sealing hiding places.
