I have a large Ctenanthe burle-marxii indoor house plant with a strange problem.
I've has the plant for around 3 years, however around 6-months ago, the plant started displaying a problem where the underside of almost every leaf has many small white 'secretions' that are sticky to the touch. These secretions leave a sticky residue to anything that comes in contact with them.
Each secretions seems to represent a small hole on the upward facing part of each leaf.
Apart from these annoying sticky secretions, the plant seems otherwise healthy.
Does anyone have any idea what might cause this?

Thanks for any advice!

Your plant looks to have more than one type of plant pest. You will have to thoroughly wash down all of the leaves covering all surfaces with a solution of 5 parts water, 1 part alcohol, and a squirt of liquid dish soap. After spraying wipe down all the leaves to remove the carcasses. Then respray so that the solution runs freely into all the nooks and crannies.

Pest-infested plants are often plants that are under stress for other reasons, such as improper light or watering so check into that.
