Sprayable compositions comprising a pyrethroid, a viscosity building agent, an emulsifier or surfactant, and an emollient are provided. The compositions have a viscosity that allows for delivery of the spray from a pressurized container such that the pyrethroid is administered in a consistent amount that uniformly covers the body of a subject. This obviates the need to rub the composition into the skin. In preferred embodiments, the pyrethroid is permethrin； the viscosity building agent is selected from the group consisting of carbomers, xanthan gum, or a combination thereof； the emulsifier or surfactant is selected from the group consisting of glyceryl mononstearate, PEG40 hydrogenated castor oil, cholesterol, steareth-10, steareth-20, and combinations thereof； and the emollient is selected from the group consisting of C12-C15 alkyl benzoates, diisopropyl adipate, silicon oil, mineral oil, or any combination thereof.
