I have found these white moths (very small, winged, can fly) below the leaves of my Arabian jasmine plant, and the plant has stopped flowering and is in a poor state. There are surprisingly some white scaly patches too on the leaves, though I am not sure if these are related with the white moth. They look more like fungi to me though I might be wrong. I have tried using insecticides but they don't seem to be working, and the moths and the scales keep coming back. Can anyone please help me identify the insect/fungus and suggest a remedy?

white fly and scales

Happened to my jasmine plant recently and it stopped flowering for a couple of months. I sprayed some alcohol on the underside of the leaves for a few days straight, trim away damaged leaves and fertilized the soil. She is flowering again almost immediately after that.


As the renowned Stephie has pointed out in the comment this is Whitefly which is a very common pest. The scales are discarded pupae cases from the larvae.

The key in pest control is to:

  • remove other sources of whitefly which can reinfect the plant. Are other plants infected? Remove them and isolate this plant from healthy ones
  • spray with 5ml dish soap to one liter of water, or, wipe down with a cloth soaked in the solution
  • repeat at five to seven day intervals so you catch the eggs as they hatch
  • three applications or more are likely to be needed
  • 1

  • Does wipedown really work on a jasmine? Otherwise that answer is what I would do... @Stephie you are "The Renowned Stephie" :D

  • @J.Musser clarified you have to wipe w soap and water. Tedious and time consuming but effective

  • @kevinsky Yes, naturally. I just meant using a small sprayer seems like it would give much better coverage, as not all plants are apt for a wipedown.

  • @J.Musser a wipedown will crush the eggs that will otherwise be unharmed by soap and water. It's only the pyrethrins and perhaps neem oil that have a residual activity that will control the next hatching without more attention. Some people don't have sprayers and have lots of time. That method is for them.
