The American cockroach is probably the largest cockroach that infests dwellings and utilities. Adults are red-brown in colour and the area behind their head is outlined with a yellow band. Egg cases are usually dropped or glued to surfaces within reasonable proximity to food and water. Up to sixteen eggs may hatch from each egg case, and the nymphs may take six to twelve months to develop into adults. Adult lifespan may be six to twelve months and females may produce up to fifty egg cases.
As the American cockroach prefers warm, moist and dark conditions, it tends to live indoors in colder regions but mainly outdoors in warmer regions. Partly because of its large size, it tends not (so often) to infest the dwelling parts of buildings (unlike German cockroach, see here for more details). American cockroaches enter into houses and offices to find water or food. These cockroaches can simply pass under doors if the weather-stripping is damaged. Basement windows and garages are also typical entryways. When American cockroaches enter houses, they often go to bathrooms, kitchens, laundry rooms, and basements. Nevertheless, it is a very widespread pest, occurring in wall, roof and sub-floor voids and in and around sewers, drains, moist cellars, grease traps and rubbish dumps. Buildings infested or visited include hospitals, bakeries, food stores, warehouses, factories and domestic residences (please check here for more information about problems with cockroaches). It seems to have a preference for decaying organic matter, but will eat most human or animal foods and also book buildings, paper and clothing (particularly if soiled). Adults with a water source may survive for about two to three months without food.
The American cockroach is fully winged and apt to fly in warm weather (albeit for only relatively short distances at a time). Egg cases glued to food packages or boxes, pallets and the like, play an important role in its dispersal.
American Cockroach Infestation
Property owners may find these active cockroaches. American cockroaches are able to run surprisingly fast and they typically scurry into a dark spot. If they are startled, American cockroaches can easily fly. American cockroaches leave their droppings in the dark areas where they hide. Property owners will possibly find these droppings in basements, in pantries, or behind appliances. American cockroach droppings can be 30 mm long. Sometimes people mistake them for mouse droppings. American cockroach droppings have ridges on the sides and they are blunt on the ends. Mouse droppings have pointed ends. Since mice groom themselves, mouse droppings quite often have hairs embedded in them. American cockroach egg cases are about one cm long. They are dark-coloured – reddish or blackish brown. Home owners occasionally see these egg cases in basements, in laundry rooms, or kitchens. The egg cases can be under cabinets or behind appliances. American cockroaches additionally deposit their egg capsules behind stored objects in garages and sheds. Cockroaches make a chemical called an “Aggregation Pheromone”. The odour of this chemical motives the cockroaches to stay together in groups. A lot of people explain the odour of these pheromones as having a “musty” smell. As the cockroach population begins to grow, everybody with sensitive noses may begin to recognize this odour.
