According to the Bifen IT product MSDS, the concentrated product disposal methods will vary from one region to another. The Bifen IT manufacturer recommends that you contact your local authorities to inquire about proper disposal methods in your community. Once the Bifen IT is diluted and you find you have too much extra diluted solution, you can simply pour out the extra solution right up against the foundation of your home.
