Are Bifen Granules safe to use in a basement (dirt floor) and crawl space? Concerned about toxic vapors....
Bifen Granules would not be recommended for any type of indoor use because the granules must be watered in, something that could not or should not be done in a basement. You can use something like Bifen IT to spray indoors on a dirt floor in a basement or in a crawl space. It does not need to be watered in. Bifen IT is very safe to use indoors when used as directed on the product label.
