Whiteflies multiply quickly and because they have wings, they can spread to nearby plants. Look underneath leaves for this pest. When you bring a new plant home, isolate it for two to three weeks. If pests do show up, isolating it will help prevent the pest from spreading to other plants. Brett Schaefer from Schaefer Greenhouses Inc., in Aurora, Ill. believes that proper care can go along way toward preventing pests.
Houseplants require some basic care to remain healthy and vigorous.
If the leaves are covered with dust, it reduces the plant's ability to produce its own food. Simply wiping glossy or smooth leaved plants regularly with a moist, soft cloth can prevent dust build up. Instead, you should rinse them gently with warm water. If you do notice an infestation of pests, take care of the problem immediately. Delaying will only give the bugs a chance to spread to more of the plant or to other plants in your home.
