    Anyone with thoughts or experience using spinosad (Captain Jack's Dead Bug) on Pleurothallids and other "fragile" taxa? I think I've got thrips on some of my Lepanthes / Masdevallia and have heard of people using this as a dunk for pests.
    Any thoughts, positive or negative?

    I have used spinosad on any number of different orchids without issues, but I have no specific experience with pleurothallids.

    Thank you Ray, I appreciate the advice!
    Have you found spinosad to work well on thrips? Or should I go for a different pesticide?

    Mostly, I'm hesitant because I'm planning to treat a large number of plants at once, and would hate to make a mistake.

    You’ll need to dunk them a couple of times, 10-14 days apart to get rid of thrips

    Always a good idea to test a few plants you don't mind loosing before you treat a large number.

    That's a great point! I'll give that a shot. I have a few species with multiples.

    Check on the interval between treatments. I’ve been seeing 5 days for thrips.

    Depending on the immigration of them into your growing area, what about using a beneficial mite against them?

    I haven't tried beneficial mites before! That is a really interesting idea. Have you had success with them knocking out thrips populations?
