They are very small and slow reproducing.A month ago I noticed stippling but never could find any bugs. The Dr.Zymes was not 100% effective. Will use spinosad perhaps.They don't do much damage but it was a shock to find a pest I have never seen before indoors. They look like an immature stage maybe but I have not seen any adults in a months time. They are sap suckers and cause minor stippling.There is a fungus gnats wing in photo that shows it's relative size.
