Wendy,

You probably don't need to try the Bayer product. Imidacloprid is the
chemical that kills the bugs in both Mavrik and the Bayer Shrub & Brush.
Mavrik is available in a far more concentated product so it costs more but
goes much further.

From what I have read do not rely on it to kill mites. Plants treated with
Imidacloprid may even attract them.


Yes, that's a common side effect. I believe it's even listed in the fact
sheets for some of the products containing the chemical. They suggest
the use of a miticide as an alternating treatment.
