Signs of a Cockroach Infestation
Cockroaches prefer to live and feed in the dark, so a cockroach seen during the day is a possible sign of infestation.
They are nocturnal insects and prefer dark, moist places to hide and breed.
They can be found behind refrigerators, sinks and stoves, as well as under floor drains and inside motors and major appliances. Because they can flatten their bodies to fit into narrow areas, cockroaches may also be found hiding beneath rubber mats, behind wallpaper and within wall cracks.
