Eliminating Scale on Bird of Paradise

The brown spots and sticky honeydew on your Bird of Paradise are caused by scale insects. Thorough treatment is essential: drench all leaf and stem surfaces (including the furled new leaves) with an alcohol‑soap spray (1 part rubbing alcohol to 5 parts water plus a drop of liquid soap) or a silicon‑based foliage cleaner like Brand X. Repeat in 5–7 days to catch newly hatched crawlers, then monitor weekly.

Scale can spread to other plants, but prompt treatment contains it. The insects don't harm human skin, but wear gloves if you prefer. Persistence is the key to eradication.
