The adult German cockroach is 10 to 15mm long. The Common or Oriental cockroach is 20-24mm long. The female carries an egg case from which up to 30 nymphs can hatch. They are rarely able to survive outdoors in the British climate but thrive around the heating ducts and boiler rooms of large centrally heated buildings e.g. hospitals, bakeries, hotel and restaurant kitchens, laundries, and blocks of flats. They cluster around pipes, stoves and sinks, especially in humid areas.
Both species eat any sort of food and are most active after dark from their inaccessible harbourages to forage, contaminating food and food utensils or food preparation surfaces as they go. They taint food with an obnoxious smell and may be carriers of various diseases, including food poisoning.
Good hygiene is essential to deter these insects. Melford can apply baits / insecticides to control infestations. We can also monitor the premises and recommend proofing and hygiene strategies.
