If they are really infested I would toss the, and buy your Mom a new one. I had to toss my sago palm because I could not get rid of them. I have been told that scale can be in the soil too. So just getting them off the plant is not going to help. You need to use chemicals. Make sure you get the whole plant, top and bottom of the leaves and the soil. I use "Ortho Systemic Insect Killer", but still ended up tossing my sago.

yeah, the garbage is probably where it will go. It's pretty bad.

Thanks, Passion!
