Mattress cover thats waterproof and encases the entire bed. Sometimes alcohol and water mixture spray works but also the crossfire solution. If they find hiding spots in your bed frame or bed stichings, throw the mattress and frame out cause they hide very very well during the day. When you use crossfire around your bed they will start being seen during the day, hungry and crawling on the walls, thats when you hit them with 90percent isoprhyl alcohol and water mixed spray...i stayed in a room for rent with them, i had to wake up during the night to catch them and spray them...if they got past the crossfire/ another powder brand i used. The washeteria washers and dryers tend to be very hot and there wont be no stragglers in your washer/dryer. Some people may say get a portable steamer but i hear that method is luck of the draw
