We have not heard any feedback on Bifen IT becoming gel-like when mixed as directed on the label. Make sure you are shaking the concentrate well before tank mixing, and agitate thoroughly before and during applications to ensure that the mixture has gone into solution. You can also contact the manufacturer Control Solutions for additional support by visiting their website's contact page here.
Bifen IT cannot be used in pastures where animals graze. If there are no grazing animals, let us know what you are treating for, for specific rates.
