Have sprayed the entire lawn a month ago…They came back right within 2 weeks in large numbers—- Sprayed again the entire lawn then…now 2 weeks later they are coming back, especially in eared of the yard. Can I spray as often as needed Ordovician needs to wait?
Bifen IT should be applied every 30 days. If there is a lot of rain that month that may affect the residual it can reapplied at 3 weeks but not any sooner than that. Bifen is not a contact kill & leaves a residual that continues killing as it comes in contact with treated areas. Too many applications too soon will make the product stop working entirely
