Shockwave does have a slight odor when first dispensed, but it does dissipate quickly. If you are using Shockwave indoors as a fog than of course you need to vacate the premises for at least 3 hours after fogging. If you are using Shockwave outside in a misting system of fogger, then you can re-enter the area much sooner.
