Mystery Insects on Indoor Hibiscus: Likely Ladybug Larvae, Not Pests

Beneficial Insects

The black, fuzzy, rice‑shaped insects with legs clustered at the front are likely ladybug larvae. They are voracious aphid predators and indicate your biological control is working.

Do Not Spray

If no plant damage is visible, wait and observe. Spraying would kill the beneficial larvae. Yellow sticky traps can catch adult whiteflies if they appear.

Pre‑Entry Treatment

Next season, spray hibiscus with a systemic insecticide (e.g., Orthene) a day or two before bringing indoors to prevent hitchhikers.
