 To Get Rid of Scale Insects:

  • Scale insects can be difficult to get rid of but spraying with PLANThealth Spectrum and/or Organic Insect Control followed by Organic Super Spraying Oil is most effective, killing scale through suffocation. However, do not spray in the middle of the day or in strong sunlight or high temperature as this can cause burning of the plant. It is best to apply to the crawling and young stages of scale insect.
  • Once control has been achieved PLANThealth Spectrum is a good option for prevention and control of scale and the mould that often accompanies them. They can also be applied before (at least one day) application of Organic Super Spraying Oil.
