don't bother with Bayer
My gumbo limbo tree looks healthy, but these dadburn whiteflies have been having a BIG ol party on it. Sprayed it with some Ortho stuff & that got rid of em, but they returned after ~6 months.
Next up has been a $25 can of BAYER ADVANCED 64 Oz. Tree and Shrub Protection granules. After ~8 weeks of no improvement I called Bayer. A fone flunky eventually answered, said it can take up to 3 months to start to work, and sez so on the label. I asked where, & she admitted that it doesn't. That's all she offered.
Bayer Advanced...lousy product & service
