What kills whiteflies on citrus trees?

Horticultural oil applied in spring smothers eggs and nymphs. Insecticidal soap and neem oil kill adults and nymphs on contact. For severe infestations, systemic insecticides containing imidacloprid are highly effective but should not be used during bloom.

How do I know if my plant has whiteflies?

Disturb the plant — if a cloud of tiny white insects erupts from the undersides of leaves, you have whiteflies. Other signs include yellowing leaves, sticky honeydew, and black sooty mold.

Why do whiteflies keep coming back?

Whiteflies develop resistance to insecticides quickly when the same product is used repeatedly. Rotate between different product classes and use biological controls to prevent resistance buildup.

Are whiteflies harmful to humans?

No. Whiteflies do not bite or sting humans. They are only harmful to plants, where they cause damage by extracting sap and transmitting plant viruses.
