A few leaves on my orange tree have this.

cottony scale

cottony scale 2

What is this? What can I do about it?

    My first guess is that it's some kind of scale - maybe cottony cushion.

I agree with Ed that this is most likely to be a cottony mealybug.

  • You can control this taking a paper towel soaked in dish soap and water and wiping the leaves down.
  • Repeat for every leaf with the symptoms. Check the axils where the leaves join the stems too.
  • After the treatment rinse or spray with water to prevent a soapy buildup
  • repeat every five to seven days for at least three times
  • continue to monitor as mealybug is hard to get rid of
  • move the tree away from any other houseplants. Some adult mealybugs have wings and fly to spread the population.
  • check for other plants that may have it too
  • Tks guys, this is a help.
