This palm (which I plan to identify soon, but I'm thinking it's a Cycad, hasn't really done well since we moved in. Mostly shade might have something to do with it, but I think it's most likely these bug things that I just noticed. They're ALL over!

On the leaves they look like they might be.. sacs, on the stems they look like thin white bugs.. well, you'll see with the picture.

What are they and how do I get rid of it? The ferns around it or any of the other plants don't seem to be bothered by it.
