Cockroach Control Adelaide is a contact pesticide, specifically formulated for effective, economic, long-term control. When a sewer manhole is sprayed with Cockroach Control Adelaide, cockroaches do not run deeper into the sewer or on to the street. Once a sewer cockroach comes in contact with Cockroach Control Adelaide the mucous secreted by the insect’s feet will dissolve the polymers designed to hold the insecticide micro-particles on the treated surface, and the insecticide is then immersed into the insect’s feet killing them typically within 24 to 48 hours.
