Frederick from Florida writes,
Bifen IT residual?
I recently sprayed my yard and turf grass with this product, was wondering if the product will still work after heavy rainfall. It was dry for 24 hours prior to rainfall
Bifen IT has a residual of up to 2 months indoors and out. As long as the product was dried, before the rain, it should not have washed away.
