Instead of dumping the surplus mixed Bifen IT somewhere, with whatever toxicicity concerns that entails, can I just keep the mix in the jug and re-dose the old mix a month or two later with a new shot of Bifen?
No, once Bifen IT has been mixed with water it either needs to be used or discarded within 24 hours of mixing with water. Do not let Bifen IT sit in the sprayer for longer than 24 hours as the dilution starts to separate and will clog the lines of your sprayer.
