The
Bed Bug Mattress Covers do not have to be washed before you use them. 90% of our customers do not wash them before they place them on their beds. Washing the covers does soften them a little bit since when you first take them out of their packaging they can be a little rough to the touch. This is usually never an issue though once it is on your bed and you have a sheet over it. Almost all of our office staff has a cover on their bed at home and none of us have washed it before initial use. I am not familiar with SleepTite EPA exempt spray because we only sell professional products. It seems that it is similar though to our
Steri-Fab spray, which kills all stages of bed bugs, even the eggs.
