Question: Is one cockroach a sign of infestation?

Answer: While one cockroach doesn’t make up an infestation - doing nothing or failing to see that one cockroach usually means an infestation is looming in the future unless Integrated Pest Management actions are taken and a thorough inspection conducted to make sure that one cockroach seen isn’t one from a larger group of cockroaches clustered somewhere inside or outside. Cockroaches often “hitchhike” inside with cockroach-infested goods or by entering through a door or some entry point (gap, crack or hole) that allows access. Keeping cockroaches out of the home or business is challenging; doing nothing when one or more cockroaches are seen is an invitation for future cockroach problems.
