Permethrin SFR 36.8% cannot be applied to matttresses for any treatment and can only be applied as spot treatment to upholstered furniture. The mix rate to apply indoors is 1 2/3 fl. oz. per gallon of water. For Flea Control Indoors, the product label states on page 43: Prior to treatment, carpets and furniture should be vacuumed thoroughly and vacuum cleaner bag discarded in an outdoor trash container. Evenly apply a direct spray as a spot treatment to infested areas such as crawlspaces, rugs, carpets, pet beds and other pet resting areas. Do not wet or soak. For crawlspace applications, the applicator must wear a respirator recommended by NIOSH for filtering spray mists and organic vapors. When treating upholstered furniture take care to treat between and under cushions. Pay particular attention to areas which are frequented by pets. Old pet bedding should be replaced with clean, fresh bedding after treatment. To control the source of flea infestations, pets inhabiting the treated premises should be treated with a fleacontrol product registered for application to animals.
