Biological methods have also been proposed to control whitefly infestation, and may be paired with chemical methods. Washing the plant, especially the undersides of leaves, may help reduce the number of the pests on the plants and make their management by other methods more effective. Whiteflies are also attracted by the color yellow, so yellow sticky paper can serve as traps to monitor infestations. Dead leaves or leaves that have been mostly eaten by whiteflies can be removed and burned or carefully placed in closed bins to avoid reinfestation and spreading of the disease.

Early detection in combination with hosing or vacuuming of diseased portions as well as removal of any section that is heavily infested. Pesticide use is not ideal in the case of controlling whitefly and widespread contamination can be costly; it is best to avoid this problem with aggressive preventive measures.

Several predators and parasitoids may be effective in controlling whitefly infestations, including green lacewings, ladybirds, minute pirate bugs, big-eyed bugs, damsel bugs, Encarsia formosa and phytoseiid mites.

Integrated management of whiteflies can as well be done using biopesticides based on microbials such as Beauveria bassiana (effective on larvae and adults) or Isaria fumosorosea.

Green lacewing larvae have voracious appetites, so will attack whiteflies, as well as other pests, including aphids, mealybugs, spider mites, leafhopper larvae, moth eggs, scales, and thrips. They also can attack other insects, including caterpillars. They are available as eggs from commercial insectaries, and will stay in a larval stage after they hatch for one to three weeks. The adult insects can fly and will feed only on pollen, honey, and nectar to reproduce. Repeated application may be necessary and the eggs could be eaten before they hatch by their natural predators, such as ants or mature green lacewings.

Ladybirds are also used. They eat mostly insect eggs, but will also feed on beetle larvae, aphids, scale insects, and young caterpillars. Adults are often collected when in a dormant state in the wild and shipped for use in pest control; however, they may not stay in the location where they are released. They do live for about a year and will continuously lay eggs and reproduce. Spraying the bugs' wings with a sticky substance before release may hinder their ability to fly.

Some promising claims have been made that mesh or film that excludes ultraviolet of certain wavelengths from a greenhouse interfere severely with the ability of whitefly and various other greenhouse pests, to find their food plants. It is not yet clear, assuming that the effect is substantially of value, how readily pests in such circumstances might develop behavioural tolerance to such control measures.
