Been using 1.25 per gallon but no control evident.
You may want to mix in an IGR to breakdown the reproduction cycle. By mixing Nyguard IGR in with the bifen mixture it will prevent the eggs, larvae or nymphs from maturing into reproductive adults thereby controlling future infestations.NyGuard IGR will cause morphological anomalies or changes and disrupt the expected insects' state of development, leading to sterility or death. Nyguard is also great because it is photostable and will withstand the suns UV rays for up to 6 months.
