No way! Haven't since I left college and a shared room--I leave the covers pulled down cause I saw that same tv show about killing the dust mites that are there due to us! I keep the doors closed to the bedroom--on rare ocassion that I know I'll be showing off a quilt in the room, etc I will make the bed and then give DH 2 days notice so he can get all the stuff he's has stashed around the bedroom picked up, too. I don't allow dogs (no cats) in the bedrooms, the library, the basement(long arm), the sewing room or on furniture--so that minimizes the amount of dirt. I always use a mattress pad and pillow case--they protect the mattress. I also always use a bottom and top sheet--know people that don't use top sheet but that would seem to get your covers dirtier quicker??
