The American cockroach is one of the most common types of roaches found in homes. They are usually known as ship cockroach or Bombay canary.



The average length of American cockroach is 1.6 inches whereas it is about 0.28 inch tall. They are reddish-brown in color and on their pronotum, they possess a yellow margin. There is no difference in the body of adults and immature American cockroaches, except that their immature roaches don’t possess wings.


American cockroaches have the ability to swiftly move around and hide in small cracks and crevices whenever they perceive a threat. They are known to be one of the fastest insect species and can travel at the speed of 5.4km/h. if we compare this speed to human speed, then it’ll estimate around 330 km/h. American cockroaches are nocturnal insects and are active late at night. Their compound eyes help them provide the night-time vision.

These cockroaches prefer to live in hot and damp places and the ideal temperature for their survival is around 29°C and they cannot survive in cold weather conditions. They have the ability to survive in dry places and surroundings, only if they have access to water sources around.  They are usually found in basements, porches, corners of the houses, sewers and hide in small cracks and crevices there.


If you sense “musty” smell in the basements, kitchens or around cabinets, then this could be a sign of American cockroach infestation. They produce “aggregation pheromone” chemicals; therefore if there is a serious infestation, there will be a large amount of chemical and people can detect the smell.

If you spot droppings in your basements, kitchen, under appliances or other dark places (as American cockroach hides in dark places) then this clearly indicates towards the presence of American cockroaches. Look for their egg capsules, they are around 38mm long and can easily be seen. These blackish brown or reddish color cases visibly hints towards American cockroach infestation.


Like most pests, American cockroaches also invade houses in search of food and water. Broken window panes, damaged weather stripping, garages provide easy pathways to American cockroach to enter your house. Once they enter, they usually hide in bathrooms, basements, kitchens, laundry rooms or under heavy appliances because they need dark places to hide.
