    I saw that no one had responded to you. The answer is that it depends. It depends on how concentrated the product is - PCO professional products are much more concentrated than the over the counter stuff you can buy

    it also depends on what you are spraying it on. more porous materials will likely not have as long a residual as metal or less porous

    Each manufacturer's product should give you the data on the residual length

    some pyrethrin-based based products will break down in as quick as a few days others may last up to 2 weeks
