RE: Brown Scale on ferns

Most systemics are ineffective on chewers and nibblers.

I don't know why Imido. is not effective on hard scale.  In my experience it
helps a little, but does not control.

Another example of a hard scale is Orchid, or Boisduval Scale.

Question:  IF, as "they" say, Imidocloprid is systemic and kills all
suckers, chewers, niblers and sampler...why wouldn't it work on hard
scale.  Not a challenge...just confused.
