Whiteflies are not known to bite humans, but they do have piercing mouthparts they use to extract fluids from plants.

Can whiteflies harm humans?

“They damage plants, but besides irritating people they do little else in the way of harm to humans,” Ebrahim Azizkhani, an entomologist, told Borna News Agency. Azizkhani admitted that whiteflies may cause breathing difficulties when they enter the mouth or nostrils, “but it's nothing serious worth panicking over.”
