You can sprinkle boric acid around, walk it into the rugs and stuff for a few days before vaccumming. Chem house won't make you feel better but it will make you feel better than the lice.

i googled boric acid: nasty

"Boric acid, also called boracic acid or orthoboric acid or Acidum Boricum, is a mild acid often used as an antiseptic, insecticide, flame retardant, in nuclear power plants to control the fission rate of uranium, and as a precursor of other chemical compounds. It exists in the form of colorless crystals or a white powder and dissolves in water. It has the chemical formula H3BO3, sometimes written B(OH)3. When occurring as a mineral, it is called sassolite."

"All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third it is accepted as being self-evident."
