As far as furniture and clothing goes, Licefreee Spray! was not developed to be used on inanimate objects. The conditioners in it may stain or cause oil spots. A thorough vacuuming should take care of any lice on there, or you can use Licefreee Home which is designed to kill lice on furniture and bedding. If you have throw pillows, bag them up for 10 days to make sure the lice are dead, or you can throw them in your dryer on the hottest setting to kill the lice.
