How harmful are permethrin fumes while treating clothing?
It is recommended that treating clothing with the permethrin aerosol be performed outdoors. If the treatment is accidentally carried out indoors, no adverse health effects are expected based upon calculations of inhaled dose. However, individuals with breathing problems, such as asthma, may be at greater risk. The odor arising from treating fabric with permethrin is mostly from the aerosol propellants rather than from the insect repellent itself.
