Hi everyone. I've had the palm for almost two years and always thought the brown spots were from the sun until it started to die. The dracena elephantypes (?) came from Walmart and I thought it was just sand in-between the leaves until I saw the leaves die and a sappy, honeydew substance on them. My Mexican cucumber was also doing fine overwintering until I checked the back sides of the leaves, which keep dying off one by one. I am trying to contain this so it doesn't spread, but it looks like something similar is on my hibiscus (not shown) though it could be a type of fly.
I don't want to throw them out, as they have sentimental value, one being from my wedding. Is there a horticulture oil I could purchase to kill the pests/could someone help ID what the pests are? I think the palm has Florida red scale, but I'm not sure about the others. I live in western Wisconsin, close to the border of Minnesota, so outside plants come in for the winter and go next to each other in the sunniest room.
