'Once they move in, they do not move back out. An infestation, however, is when the roaches are living and completing their entire life cycles in a house.Invasions are easier to manage by identifying how and why they arrived in the first place, then closing up entry points to a house and eliminating the few that have already entered. An invasion is when roaches have only just sought refuge in a house, like when you open your garage door and see a roach scuttle across the concrete.Domestic roaches, on the other hand, tend to coexist with humans in homes all the time.īecause of this difference, Hodges likes to classify the arrival of peridomestic roaches as either an infestation or invasion.

Peridomestic roaches live in our surroundings but will typically migrate indoors once the weather gets colder.Scot Hodges, vice president of technical services for Arrow Exterminators, says cockroaches fall into two categories: domestic or peridomestic. No bug infestation is a particularly fun experience, but roaches somehow take things to a whole new level. You probably know the feeling - the stomach-dropping moment when you hear a faint scuffle on your floor and look up to see a large, dark roach scuttling across your room or kitchen.
