How to keep roaches away from your bed
Look for potential entry points to your bedroom.
Take a few minutes to search your entire bedroom for places where roaches could potentially get in from outside. Take a close look at where the walls meet the floor and ceiling in your room, the corners, the air vents, and around the windows.
Keep in mind that roaches can slip through cracks and holes that are as small as 3 millimetres (0.12 in) high. Seal up the cracks with a caulking gun.
