It's got a few branches like this. Some of the new ones that are growing have a lot of these in the inside where the branch is opening up into leaves. What should I do? is this plant salvageable? should I keep it away from other plants? It's sitting (and in contact with) right next to my monstera

thanks

Welcome! It's hard to tell form the photo you posted. Please post a photo that shows the entire plant and its pot.

I'm thinking mealybugs, but hard to tell without a closeup. Looks like pests as they are randomly all over the leaves rather than in a symmetrical pattern. I would definitely isolate your palm till you know for sure.

I agree It's been many years since I have had mealybugs, got rid of them but can't remember how. Hope someone here can give you a formula to save your plant.

The bad news is that those are mealybugs and difficult to treat successfully on a plant that size. The good news is that your Palm does not appear to be a Majesty Palm. Palm species are often hard to distinguish in photos, but I believe yours is either a Chamaedorea or an Areca Palm. Both of those species have a much better track record than Majesty when used indoors.

Mix a solution of 5 parts water, 1-part alcohol, and a squirt of liquid dish soap. Then, spray all leaf and stem surfaces until they are dripping wet. If you just treat the visible mealybugs, you will miss the translucent and nearly invisible juveniles that will mature and reproduce. Thus, it is important that you spray ALL leaf and stem surfaces until they are literally dripping wet.

Thorough coverage is the key to successfully eradicating the problem and avoiding repeat treatments. It is a very messy task, but unless you get complete coverage and make direct contact even with the ones you cannot see, the survivors will reproduce, and the infestation will return. Be sure the solution runs into the crevices where leaf stems attach to the main stems.

Thank you!

should I do this many times? will they die but stay on the leaf? how do I know if I treated the plant successfully other than it doesn't become completely infested?

It depends on how thorough you are in getting complete coverage. After treating with the recommended solution, then wipe off any visible carcasses that remain so the plant looks clean. Every week inspect your plant carefully and watch for the return of any mealybugs and spot spray as needed.
