Icky white stuff on HousePlants is Mealy Bugs

one of the leaves on my plants has had this on it for a couple months. It is now spreading. I’m sure I should have addressed it sooner. What to do now?

It looks like your plant has Mealy BugsSee a picture, learn to identify and treat Mealy Bugs, a houseplant pest that leaves sticky,white, cottony residue on houseplants.. Am I correct that what I am looking at is white, sticky, cottony residue. This is what the Mealy BugsSee a picture, learn to identify and treat Mealy Bugs, a houseplant pest that leaves sticky,white, cottony residue on houseplants. leave behind. You can read about Mealy BugsSee a picture, learn to identify and treat Mealy Bugs, a houseplant pest that leaves sticky,white, cottony residue on houseplants. and how to treat them in the Glossary of the website. Yes, you should take care of it ASAP because it will spread to all of your plants. It looks so bad you may want to spray the back of the leaves with straight rubbing alcohol rather than the “ green solutionIf you don't want to use a commercial chemical product to treat plant pest problems try the “Green Solution.” This is a mixture of water, alcohol, biodegradable liquid soap, and mineral oil. Always test any spray on one or two leaves to be sure it won’t damage the plant. Depending upon how severe the infestation is, you can use these ingredients in varying proportions. If there are only a few pests, dip a Q-tip in alcohol and gently swab them off. For a more widespread problem, start by using a spray of warm water mixed with a few tablespoons of biodegradable soap. If that doesn’t cure the problem, make a solution using 8oz. water & 8oz. alcohol, add two tablespoons of biodegradable soap and two tablespoons of mineral oil. Spray all areas of the plant. Use this solution on leathery leafed plants (except palms), never on fuzzy leafed plants like African Violets or Begonias. For palms, omit the alcohol from the Green Solution. Never spray a plant that’s sitting in the sun or one with very dry soil.    ” I recommend in the Glossary.
