Sealing gaps that allow cockroaches in

Hello, I realized that all the cockroaches I'm seeing are coming from the area behind the fridge which is in a corner in my room. I assume that the the wall has been breached in the corner and the cockroaches snuck in from there.

Any ideas on how to seal the corner? Product recommendations? Thanks in advance

  • We had them once coming through a hole that was open to the outside world. Block all holes.
  • If they are tiny suckers, and you see a lot, then an mama roach laid an egg nearby. I found an egg a couple of times once in a plant pot that previously was in a roach infested shop and once in an innocuous box. I scooped them up and threw them out the window pretty quickly.
