Whiteflies on Ornamentals in Southwest Florida
If you’ve noticed small white insects flying up from your shrubs when you walk by, you’re likely dealing with whiteflies — one of the most common ornamental pests in Southwest Florida.
Whiteflies become increasingly active as temperatures warm, and they can quickly weaken shrubs if not treated early.
What Are Whiteflies?
Whiteflies are tiny, winged insects that feed on plant sap. They typically live on the undersides of leaves and fly up in a small white cloud when disturbed.
Like aphids, whiteflies reproduce rapidly, especially during our warm Southwest Florida climate.
Common Ornamentals Affected in SWFL
Whiteflies frequently target:
Hibiscus
Ixora
Gardenias
Ficus
Viburnum
Crotons
Ligustrum
Some species, like ficus whitefly, can cause severe defoliation if left untreated.
Signs of a Whitefly Infestation
Whiteflies often go unnoticed until damage becomes visible. Look for:
Leaves turning yellow
Sticky residue (honeydew) on foliage
Black sooty mold forming on leaves
Premature leaf drop
A cloud of tiny white insects when plants are disturbed
Heavy infestations can stress shrubs and reduce flowering and overall plant health.
Why Whiteflies Are a Bigger Problem in Southwest Florida
Our extended warm season allows whiteflies to reproduce year-round. Without consistent monitoring and treatment, populations can explode quickly.
Additionally, once sooty mold develops from honeydew buildup, it blocks sunlight from reaching leaves, reducing photosynthesis and further weakening the plant.
Professional Whitefly Control
At Westfall’s Lawn & Pest Control, we use targeted treatment methods designed to:
Eliminate active whitefly populations
Interrupt the reproductive cycle
Protect new growth
Reduce reinfestation
Because whiteflies live on the undersides of leaves, proper application technique is critical for effective control.
Early Detection Makes the Difference
The sooner whiteflies are addressed, the easier they are to manage. If your ornamentals are yellowing, dropping leaves, or releasing white insects when disturbed, it’s time for a professional inspection.
