Since we are coming into Fall and I saw an article about bed bugs in Dubuque, it made me want to change, launder, and spray my mattress with the Norwex mattress spray. I use the spray about every three months. It does not kill bed bugs or mites but does help to eliminate and break down the feces and dead skin cells that mites and bugs feast on. I feel much better going to bed in clean bedding at night and sleep peacefully knowing the Norwex Mattress Cleaner is doing its work.
