Can bed bugs live in a refrigerator?

Yes, anywhere that is warm. They don't just like beds actually as I have them they like anywhere they can hide even laptops, they prefer warm if they can't find a source of wood like your box spring, I have a infestation behind my fridge, I brought in a box spring and had to through it out a week later. In a last resort they will go into your walls and come back in at night to search for food and warmth. If you have them in your walls you can't do to much but plug your sockets and keep your house neat and clean and minimize hiding spots. Oh yeah, buy a cat, the bugs hate movement and run away fast.
