I initially wanted to purchase the Talstar, as I do every year, but once I saw the price difference for the generic Bifen I/T, I tried it, and I must say, it works just as good!
I purchased Bifen I/T for the stink bug problem on my back porch, and I woke up the next day, and they were all on their backs ! The Bifen I/T worked great!
Compared to the stuff I bought at the home improvement store, there is no comparison! Bifen I/T works, and their stuff didn’t.
