Whiteflies are difficult to control once their populations grow large, so begin your control measures early in the season. Whiteflies are attracted to the yellow color of sticky traps. For best results, hang or place the cards close to the top of the plant.

Whiteflies can be controlled with sprays containing pyrethrum or neem give the best control. Both the surface & the underside of the leaf need to be covered and during the summer, a spray regime every 5 days is required.
