An areca palm I own has an insect infestation that I've had trouble identifying. I've been unable to locate any non-egg mature examples, only the eggs that tend to be in nooks around the plant, typically under leaves. They look like very tiny white cylinders that tend to be in small clusters around veins.
I removed most of the infestation and sprayed with an insecticide but it seems to be coming back. I need help with identification and figuring out a way to deal with it.
Prior to clearing it out the first time a few leaves had enough of them on some leaves to be visible from a distance, so it may be that these aren't eggs but are mature.
