Do roaches hide in mattresses?
Cockroaches will hide anywhere that is conducive for them to hide. Typically, mattresses that are being slept on would not be a great place for roaches because they could find a place where they could be disturbed less. In severe cockroach infestations, there are so many insects that the populations have to spread out and find places to live. In these instances, you will find cockroaches anywhere and everywhere.
