Should you use a surfactant when spraying with Bifen IT?
Bifen IT does not require a surfactant to be used for it unless you are treating for certain pests. According to the product label, if you are treating for mites and/or spider mites, the addition of a surfactant may increase the effectiveness of Bifen IT. Please let us know if you have any additional questions.
