There is nothing that can be added to the Mosquito Barrier to reduce the smell as that garlic smell is what repels insects from the area in the first place. The smell of the garlic oil will become unnoticeable to humans within a few minutes and will only be strong during and right after application. It could take 24 hrs or so to kill unless sprayed directly and it offers a 4 week residual.
