Controlling Whiteflies on Hibiscus

The Whitefly Problem

Hibiscus is a favorite host. Whiteflies suck sap, causing subtle speckling. You’ll notice them when disturbed—they flutter up like flying dandruff. They’re tough to eradicate but manageable with persistence.

Effective Tactics

Yellow or Blue Sticky Cards

Color attracts whiteflies; they get stuck in the glue. Hang cards in the plant canopy. Handle by edges only—glue is permanent. Cut cards if needed (sharp scissors, one clean cut). Replace when covered.

Horticultural Oil Sprays

Spray thoroughly (including leaf undersides) to smother adults and nymphs. Repeat per label. Complete eradication indoors is unlikely, but numbers can be kept low.

Last Resort

If infestation is severe, consider discarding the plant or hard‑pruning it before whiteflies spread to other houseplants.
