When I ave used the concentrate after dilution, I have preferred the indoor/outdoor versions like in your link. This is the one I used, I'm thinking it had no odor or oil spot stains but not absolutely certain(memory failing me!:Scuba wrote:I use this http://www.amazon.com/Martins-Permethri ... permethrin

There is another that I got from a garden store, specifically advertised for bed bugs and indoor use by Bonide ( .5% Permethrin), it had no smell at all, and was cheep(on sale) for a gallon spray container. I guess when buying as a gallon container, you could also just pour it into a container and dip.
