    Isolate the plant and use a Hot Shot or Nuvan strip.

    looks like: Hawaiian Scale (aka Asian Cycad Scale) - Aulacaspis yasumatsui

    I'm also looking for a systemic spray for it. I've been using rubbing alcohol wipes, and it keeps it off most of my plants except my Winged Mirabilis x Veitchii, I thought it might be because it's hirsute, but I've never seen one on my ampullaria. Maybe because there are a lot of crevices between the leaves and the stem on the Mirabilis x Veitchii. It also likes truncatas for some reason. I just picked up some Ortho Rose Pride Insect, Disease & Mite control w systemic protection and will let you know how that works.

    What is a Hot Shot or Nuvan strip? It's in my HL tank I don't know where else I could put it where it would get light and proper temps are those methods fast enough to kill the critters but not the plant if it's out of it's environs for however long?

    The rubbing alcohol seems to kill them off but they come back after a week or so, seemingly with a vengeance sometimes! LOL

    Could be the dreaded hibiscus snow scale Pinnaspis strachani

    It is not uncommon to get these on plants from Hawaii. These are an armored scale and are difficult to eradicate.

    Look for the three "ridges" on the males.

    You can use the strips in a closed terrarium. Just not somewhere where you'll be hanging out for any period of time. You'll probably only need it in there for a few hours, maybe overnight.
