Cockroach: Least-Toxic Control

Cockroaches are probably the household pest that conjure up the strongest feelings of disgust. They eat household food items and contaminate them with their saliva and excrement; they also produce secretions that leave an odour. The two most common varieties found in Northern Europe are the German cockroach and the oriental cockroach. See our factsheet for more details.
