[YEA] Just thought I'd tell you that my grandmother who was born in 1916 always told me about the time they got lice right after they had got married...and bought a used mattress after sleeping on the floor for months. They lived in rural Texas..and there was no running to a market in a wagon to get treatments...even had they the money during the depression. They certainly couldn't afford to throw away an infested mattress. They treated the mattress, bedding, AND themselves with kerosene (which they used for bedbugs in bedding when she was a child) and that took care of the problem, except for their eyelashes, which they picked off for awhile. I was always shocked when she told me about it...visualizing they soaked the mattress. She finally explained to me that they dipped a rag into kerosene and scrubbed the daylights out of it. As a result of her experience she always told me to drag out our mattresses and bedding into the sun to bake each side at least every spring, which I did faithfully till I couldn't drag a mattress outside anymore.
