Lantana attracts a surprisingly short list of serious insect pests, and most of them are sap-feeders that thrive in hot, dry weather. The lantana lace bug is the single most damaging culprit in most regions, followed by whiteflies, scale insects, and spider mites. Because lantana is tough and fast-growing, it can tolerate light pest pressure without intervention, but heavy infestations do call for action. The good news is that the control options tend to be straightforward, and choosing the right cultivar can spare you much of the trouble in the first place.
The Lantana Lace Bug
If you grow lantana, you will almost certainly encounter the lantana lace bug, Teleonemia scrupulosa, sooner or later. This tiny insect, only a few millimeters long, has lacy, translucent wings and feeds on the undersides of leaves by piercing plant cells and sucking out their contents. The damage shows up on the upper leaf surface as a stippled, bleached pattern, often described as a silvery or whitish speckling. Flip a damaged leaf over and you will find dark, varnish-like excrement spots alongside clusters of the bugs and their nymphs.
Lace bug damage is mostly cosmetic in mild cases, but heavy infestations cause leaves to yellow, curl, and drop. The bugs reproduce quickly in warm weather, and populations can explode during dry spells when natural enemies are scarce. The lantana lace bug is well documented as a pest that often causes extensive damage to common lantana.
1EDIS. Lantana Lace Bug, Teleonemia scrupulosa Stål (Insecta: Hemiptera: Tingidae)For light infestations, a strong blast of water from a hose knocks nymphs off the leaves and disrupts feeding. Pruning heavily infested branches removes the worst damage and encourages fresh growth. When populations are heavy enough to defoliate sections of the plant, insecticidal soap or horticultural oil sprayed on the leaf undersides can bring numbers down. Systemic insecticides work too, but they carry pollinator risks on lantana that are worth thinking carefully about, a topic covered further below.
Whiteflies
Whiteflies are another common sap-sucker on lantana, particularly in warm and humid climates. Several species attack lantana, but the one most studied on it is the tobacco or silverleaf whitefly, Bemisia tabaci. These tiny white-winged insects cluster on leaf undersides, and when you brush against the plant a small cloud of them lifts into the air. Like lace bugs, they feed by piercing leaf tissue and extracting phloem sap, which weakens the plant and leaves behind sticky honeydew that attracts sooty mold.
Sooty mold, the dark fungal coating that grows on honeydew, is often the first visible sign of a whitefly problem. It blocks light from reaching leaf surfaces, compounding the damage the insects themselves cause. In warm regions where lantana grows year-round, whitefly populations can persist through multiple generations without a natural break.
Natural enemies do help. Research on whitefly populations on lantana in the Jordan Valley found that parasitoid wasps attacked a quarter to half of whitefly pupae, depending on the time of year, with parasitism rates peaking in winter and dropping in late autumn.
2Wiley Online Library. Parasitization of the tobacco whitefly Bemisia tabaci Genn., (Hom., Aleyrodidae) on Lantana camara L. in the Jordan ValleyFor garden-scale control, yellow sticky traps catch adults and help you monitor populations. Insecticidal soap sprayed directly on the insects is effective against nymphs but needs to make contact to work, so thorough coverage of leaf undersides matters. Reflective mulch around the base of plants has been shown in other crop systems to disorient whiteflies and reduce landing rates, and it can work for ornamental plantings too.
Scale Insects
Several types of scale insects feed on lantana, but the one most studied is the greenhouse orthezia, Orthezia insignis. Scale insects look nothing like typical bugs. They appear as small bumps, waxy lumps, or cottony masses stuck to stems and leaf veins, and they feed by tapping into the plant’s vascular system. Heavy infestations weaken plants, cause branch dieback, and produce honeydew that leads to the same sooty mold problems whiteflies cause.
Not all lantana species are equally vulnerable. Research comparing different lantana types found that Florida’s native pineland lantana and buttonsage were highly susceptible to greenhouse orthezia, while trailing lantana and its cultivars were somewhat less so. Common shrub lantana and its cultivars were the least susceptible of the group.
3HortTechnology. Susceptibility of Lantana Cultivars to Orthezia insignisControlling scale usually starts with physically removing them. A cotton swab dipped in rubbing alcohol works for small infestations on individual plants. For larger problems, horticultural oil smothers the insects under their waxy coverings, which is important because that waxy shield makes many contact insecticides ineffective. Systemic products penetrate the plant tissue and reach scale insects when they feed, but again, the pollinator implications on a nectar-rich plant like lantana are a serious consideration.
Spider Mites
Spider mites are not insects but tiny arachnids, and they love lantana during hot, dry stretches. They feed by puncturing individual leaf cells and draining the contents, producing a fine stippling that looks similar to early lace bug damage. The giveaway is webbing. When spider mites are present in large numbers, you will see fine silky webs stretching between leaves and along branch tips, especially on the undersides.
Spider mites reproduce remarkably fast in dry heat, with a new generation every week or two under ideal conditions. A plant that looked healthy can be covered in webbing within a few weeks if you are not paying attention. Overhead watering or hosing down the foliage regularly disrupts their webbing and washes off eggs and mites. This is one case where a little extra humidity around the plant actually works in your favor, since mites prefer dry conditions and their predators prefer moisture.
Predatory mites are commercially available and highly effective in warm climates. They seek out spider mites and consume them without damaging the plant. For chemical control, miticides are the targeted option. Standard insecticides often make spider mite problems worse by killing off the predatory insects that keep mite populations in check, so reaching for a broad-spectrum spray at the first sign of mites tends to backfire.
Aphids and Mealybugs
Aphids occasionally colonize lantana, especially on tender new growth in spring. They cluster on shoot tips and developing flower buds, sucking sap and excreting honeydew. Lantana is not their preferred host, so aphid problems on established, vigorous plants tend to be mild and transient. A few rounds of hosing them off or a single application of insecticidal soap usually resolves the issue. Ladybugs, lacewings, and parasitoid wasps often move in on their own and clean up aphid colonies without any intervention.
Mealybugs, which look like small cottony white masses in leaf axils and along stems, occasionally appear on lantana grown in sheltered locations or indoors. They are slow-moving and easy to spot. Rubbing alcohol on a cotton swab kills them on contact, and horticultural oil sprays handle larger populations. The key with mealybugs is catching them early, because they tend to hide in crevices and can build up quietly before you notice the honeydew and sooty mold they leave behind.
The Seed-Feeding Fly
One pest you might never notice is the lantana seed fly, Ophiomyia lantanae. This small fly lays its eggs in developing lantana fruits, and its larvae feed inside the seeds, destroying them before they mature. The damage is invisible from the outside unless you crack open the berries and look for hollowed-out seeds or tiny exit holes left by the emerging adults.
This fly is widespread wherever lantana grows and has been studied extensively, though more for its potential role in limiting lantana’s spread as a weed than as a garden concern.
4Biological Control. Lantana camara and the fruit- and seed-damaging fly, Ophiomyia lantanae (Agromyzidae): seed predator, recruitment promoter or dispersal disrupter?For ornamental gardeners, the seed fly is not really a pest at all. It does not affect the appearance of the plant, its flowers, or its foliage. If anything, it reduces the number of viable seeds the plant produces, which is arguably a benefit given lantana’s reputation for aggressive self-seeding in frost-free climates. You do not need to control this insect, and in most cases you would not even know it was there.
Picking Cultivars That Resist Pests
Your cultivar choice matters more than most gardeners realize when it comes to pest pressure. Research testing dozens of lantana cultivars for lace bug resistance found that trailing lantana (Lantana montevidensis) and its cultivars were highly resistant, averaging almost no lace bugs per leaf sample. Among common lantana cultivars and hybrids, there was a wide range of susceptibility, but at least one resistant cultivar existed within most flower-color categories.
5Florida Entomologist. Resistance Among Lantana Cultivars to the Lantana Lace Bug, Teleonemia scrupulosa (Hemiptera: Tingidae)A similar pattern holds for scale insects. Shrub-type lantana cultivars showed the least susceptibility to greenhouse orthezia, while native Florida species and trailing types were more vulnerable to that particular pest.
3HortTechnology. Susceptibility of Lantana Cultivars to Orthezia insignisThe practical takeaway is that there is no single “pest-proof” lantana. A cultivar resistant to lace bugs might be more vulnerable to scale, and vice versa. But if lace bugs are your main problem, which they are for most people, steering toward trailing lantana varieties or named cultivars with documented resistance can dramatically reduce the amount of spraying you do. Ask your local extension office which cultivars perform well in your area, because pest pressure varies regionally.
Horticultural Oils and Insecticidal Soaps
For most lantana pest problems, horticultural oil and insecticidal soap are the first-line treatments, and they are surprisingly effective. Both work by physically coating and suffocating soft-bodied insects rather than poisoning them, which means pests do not develop resistance the way they can with chemical insecticides. They break down quickly, leaving little residue, and they spare most beneficial insects that are not present at the time of spraying.
A common worry is whether oil or soap sprays will burn lantana foliage, especially in summer heat. Testing of horticultural oil and insecticidal soap applied repeatedly to lantana and other ornamentals under commercial nursery conditions in Florida and Georgia, even on days exceeding 95°F, found no phytotoxicity on any of the plants tested.

Phytotoxicity of Sunspray Ultra-Fine Spray Oil and Safer Insecticidal Concentrate Soap on Selected Ornamental Plants in Summer in North Florida and South GeorgiaThat said, a few practical tips improve results. Spray in the morning or evening rather than in direct midday sun. Cover leaf undersides thoroughly, since that is where lace bugs, whiteflies, and mites congregate. Repeat applications every seven to ten days for two or three rounds, because oils and soaps only kill what they touch and have no residual activity. New insects arriving after the spray dries are unaffected, so a single application rarely solves the problem.
Protecting Pollinators When You Treat Lantana
Lantana is a pollinator magnet. Butterflies, bees, and hummingbirds visit the flowers constantly, which creates a genuine tension when you need to treat a pest problem. The pesticide you choose and how you apply it matters more on lantana than on most other garden plants, precisely because so many pollinators are feeding on it.
Research on pesticide contamination in lantana nectar highlights the difference application method makes. When a neonicotinoid insecticide was applied as a foliar spray, it did not show up at measurable levels in the nectar. But when the same product was applied as a soil drench, concentrations in the nectar exceeded lethal doses for several bee species.
7PubMed. Influence of pesticide application practices, pruning, and planting on contamination of nectar in container-grown lantanaThis finding has real implications for home gardeners. Systemic insecticides applied as drenches are convenient and effective against sap-feeding pests, which is why they are popular. But on a plant whose flowers are actively visited by pollinators, a soil drench can turn every bloom into a poisoned feeding station for weeks. If you need to use a systemic product on lantana, consider removing all open flowers before application and pruning back flower buds to delay the next bloom cycle. Better yet, stick with contact-only products like oils and soaps when you can, and time spray applications for early morning or late evening when pollinators are less active.
Lantana’s Own Chemical Defenses
Lantana is far from defenseless against insects. The plant produces a complex cocktail of chemical compounds in its leaves and flowers, including alkaloids, flavonoids, tannins, and terpenoids. The principal components of its leaf essential oil include lantadenes and compounds like beta-caryophyllene and alpha-humulene, which have documented insecticidal and repellent properties.
8PubMed Central. From an Invasive Weed to an Insecticidal Agent: Exploring the Potential of Lantana camara in Insect Management Strategies-A ReviewThese chemicals are part of the reason lantana is such a resilient landscape plant. Many generalist herbivores avoid it altogether, which is why you rarely see caterpillar damage or beetle chewing on the foliage. The pests that do attack lantana, like lace bugs and whiteflies, are specialists or generalist sap-feeders that have evolved ways to bypass or tolerate these defenses. This also explains why lantana pest lists are relatively short compared to those for roses, hibiscus, or other popular garden plants.
Interestingly, researchers have been exploring lantana leaf extracts as botanical insecticides for use against agricultural pests on other crops. The same compounds that make the plant somewhat self-protecting could eventually see use as ingredients in commercial pest-management products, turning a plant that is often considered a weed in tropical regions into a source of pest-control chemistry.
Biological Control Agents Used Against Lantana
In regions where lantana has become an invasive weed, some of the insects that garden growers think of as pests were actually introduced deliberately to suppress wild lantana populations. The lace bug discussed above, for example, has been released in multiple countries as a biocontrol agent. Leaf-mining hispine beetles, Octotoma scabripennis and Uroplata girardi, have also been imported and established in Australia to attack lantana. Host-specificity testing confirmed that both beetle species feed almost entirely on lantana and pose negligible risk to other plants, making them well suited for biocontrol programs.
9Bulletin of Entomological Research. The suitability of Octotoma scabripennis Guér. and Uroplata girardi Pic (Col., Chrysomelidae) for the control of Lantana (Verbenaceae) in AustraliaThis creates a somewhat unusual situation for gardeners in places like Australia, Hawaii, or parts of Africa and Asia. The “pests” on your ornamental lantana may be the very biocontrol agents that land managers are counting on to suppress invasive lantana elsewhere in your region. If you live in an area where lantana is listed as a noxious weed, check local regulations before aggressively treating insects on your garden plants. In some jurisdictions, cultivating certain lantana varieties is restricted or discouraged, and releasing insecticides that kill biocontrol agents working on wild stands nearby can put you at odds with broader weed-management efforts.
For gardeners in regions where lantana is simply a beloved ornamental and not an invasive concern, this dynamic has no practical consequence. Treat your pests as you see fit. But knowing the dual identity of insects like the lace bug adds useful context: these bugs did not randomly find your lantana. They evolved to exploit it, and in many parts of the world, that is exactly what people want them to do.
