If you used it according to label directions and only used 1/2 oz - 1 oz per gallon of water and sprayed it on the base of the house, the odor should go away in a few hours. You are basically smelling the solvents and not the chemical. It's sort of like smelling paint until is has dried on a wall. If you can smell it indoors, then open the windows and maybe doors and let the house air out. Demon WP does not have this odor and is usually recommended over Demon Max for exterior spraying.
