A new invasive pest reaches Hawaii every 18 days on average. That sobering statistic from the U.S. Forest Service reveals the relentless pressure facing the islands’ unique ecosystems and agricultural economy.
Hawaii’s geographic isolation—which once protected these islands and fostered extraordinary biodiversity—now makes them exceptionally vulnerable to invasive species that arrive hidden in cargo, luggage, and imported plants.
The consequences extend far beyond inconvenience. Invasive insects in Hawaii devastate native species found nowhere else on Earth, cripple agricultural industries worth hundreds of millions of dollars, and fundamentally alter the ecosystems that define island life.
Understanding these invaders—how to identify them, recognize their damage, and respond to their presence—represents a critical responsibility for every Hawaii resident, visitor, and agricultural stakeholder.
1. Little fire ant
The little fire ant (Wasmannia auropunctata) may measure only 1.5 millimeters long—about the thickness of a penny—but this invasive species packs a disproportionately painful sting and devastating ecological impact. Native to Central and South America, these tiny reddish-orange ants have established populations across multiple Hawaiian islands, earning their reputation as one of the world’s most problematic invasive ant species.
These minuscule ants form dense colonies in trees, gardens, homes, and agricultural areas. Their colonies can reach extraordinary densities, with thousands of ants occupying relatively small areas. Unlike many ground-dwelling ant species, little fire ants excel at climbing and frequently colonize tree canopies, creating “rain” of ants that drop onto people and animals passing below.
Important Note: Little fire ants deliver stings that cause intense, burning pain—hence their common name. The sting site develops into itchy, raised welts that can persist for days or even weeks. People with sensitive skin or allergies may experience more severe reactions. The pain and persistent itching significantly impact quality of life in infested areas.
Their ecological impact extends well beyond human discomfort. Little fire ants prey on native insects, spiders, and other invertebrates, reducing biodiversity in areas they colonize. They protect and farm honeydew-producing insects like aphids and mealybugs, which damage plants.
In agricultural settings, they interfere with crop harvesting, sting workers, and reduce productivity. They’ve been documented blinding pets and livestock by stinging their eyes, and they disrupt ground-nesting birds by attacking chicks and eggs.
The economic consequences are substantial. Property values decline in heavily infested areas as residents flee the persistent stinging. Agricultural operations face increased costs from protective equipment requirements and reduced worker efficiency. Tourism suffers when visitors encounter these aggressive ants at popular destinations.
Little fire ants spread through human-assisted transport of infested plants, soil, mulch, green waste, and equipment. A single potted plant can harbor an entire colony. Once established, they’re extremely difficult to eradicate. However, early detection and rapid response can prevent establishment in new areas.
If you suspect little fire ants on your property, report them immediately through the 643pest.org reporting system. Treatment requires sustained effort using approved baits and typically needs professional pest control expertise. Never move plants, soil, or green waste from infested to non-infested areas—this is the primary spread mechanism.
2. Africanized honeybee
The Africanized honeybee (Apis mellifera scutellata), often called the “killer bee,” arrived in Hawaii in the late 1980s and has since established populations primarily on the Big Island and Oahu. These bees are a hybrid between European honeybees and African honeybees, combining European honeybees’ productivity with African subspecies’ defensive aggression.
Visually, Africanized honeybees appear nearly identical to European honeybees, making field identification by appearance alone virtually impossible. They’re slightly smaller on average, but this difference isn’t reliable for identification. The critical distinction lies in behavior rather than appearance—Africanized colonies defend their hives much more aggressively, pursue perceived threats over greater distances (up to a quarter mile), and respond to disturbances in larger numbers.
Key Insight: Africanized honeybees aren’t inherently more dangerous on an individual basis—their venom is identical to European honeybees. The danger stems from their defensive behavior. When threatened, Africanized colonies can deploy hundreds or thousands of workers to attack, creating life-threatening situations through sheer numbers of stings.
These bees nest in smaller cavities than European honeybees prefer, colonizing locations like water meter boxes, overturned containers, old tires, wood piles, and even small holes in the ground. This adaptability to diverse nesting sites brings them into closer contact with humans than European honeybees typically establish.
For agriculture, Africanized bees present a complex situation. They’re effective pollinators, contributing to crop production. However, their aggression complicates beekeeping operations and creates safety concerns for agricultural workers. Commercial beekeepers must implement additional safety protocols and may face challenges maintaining European bee genetics in their hives as Africanized genetics spread through drone populations.
If you encounter a bee swarm or aggressive bee behavior, never attempt to disturb or remove it yourself. Move away quickly and steadily without swatting at bees—swatting releases alarm pheromones that trigger more aggressive responses. Seek shelter indoors if possible. Report swarms or aggressive hives to professional bee removal services or the Hawaii Department of Agriculture. In an attack situation, protect your face and head while running to enclosed shelter—most bee attack fatalities result from victims falling or becoming unable to escape due to disorientation from multiple stings.
3. Coconut rhinoceros beetle
The coconut rhinoceros beetle (Oryctes rhinoceros) represents one of Hawaii’s most destructive invasive pests to palms and related plants. First detected on Oahu in 2013, this large beetle has since spread despite intensive eradication efforts, threatening Hawaii’s iconic coconut palms, ornamental palms, and related species throughout the islands.
Adult beetles are substantial, measuring 1.5 to 2.5 inches in length with a characteristic horn on the head—males have larger, more prominent horns used in competition for mates. They’re shiny dark brown to black, with a robust, oval body shape typical of scarab beetles. Despite their size and somewhat intimidating appearance with that prominent horn, adult beetles don’t bite or sting humans.
The damage these beetles inflict on palms is distinctive and severe. Adults bore into the crowns of palm trees to feed on sap, creating V-shaped cuts in fronds as they emerge and unfold. Repeated attacks weaken palms, reduce fruit production, and can kill trees—particularly younger specimens or those already stressed by other factors. The characteristic damage pattern—symmetrical V-notches along the midrib of fronds—provides clear evidence of coconut rhinoceros beetle activity.
Pro Tip: Coconut rhinoceros beetles breed in decaying organic matter, particularly rotting palm material, compost piles, mulch, and decaying logs. Proper management of green waste dramatically reduces breeding habitat. Chip or grind palm material promptly, turn compost piles regularly to disrupt development, and avoid accumulating large piles of decaying vegetation.
The beetles complete their life cycle in breeding sites within organic matter. Females lay eggs in suitable substrate, which hatch into grubs that feed on decaying material for several months before pupating and emerging as adults. This life cycle means that reducing breeding habitat availability represents a critical control strategy.
Particularly concerning for Hawaii, the strain of coconut rhinoceros beetle established in the islands appears resistant to the Oryctes nudivirus, a biological control agent successfully used elsewhere. This resistance necessitates alternative control approaches and makes eradication significantly more challenging.
If you find coconut rhinoceros beetles or suspect their presence based on characteristic palm damage, report immediately through official channels. Don’t transport palm material, green waste, or mulch between properties or islands—this facilitates beetle spread. Participate in community chipping events where palm material is properly processed to destroy any developing beetles.
4. Coffee berry borer
The coffee berry borer (Hypothenemus hampei) represents the most damaging insect pest to coffee worldwide, and its establishment in Hawaii has devastated portions of the islands’ specialty coffee industry. First detected in Hawaii in 2010 on the Big Island’s Kona coffee-growing region, this tiny beetle has since spread to other coffee-growing areas.
These beetles are minuscule—females measure only 1.5 to 2 millimeters in length while males are even smaller. Their small size and dark coloring make them difficult to spot without close inspection. The real damage occurs inside coffee berries where they’re even harder to detect until damage becomes apparent.
Female beetles bore directly into coffee berries (the fruit containing coffee beans) and tunnel into the seeds themselves. Inside, they lay eggs and establish galleries where larvae develop while feeding on the coffee beans. This internal feeding destroys bean quality, leading to off-flavors in processed coffee, reduced bean weight, and economic losses from downgraded or rejected crops.
The economic impact on Hawaii’s coffee industry has been severe. The state’s coffee production—particularly the renowned Kona coffee—supports an industry worth tens of millions of dollars annually. Coffee berry borer infestations reduce yields, increase processing costs (as damaged beans must be sorted out), and threaten the premium quality reputation that commands high prices for Hawaiian coffee.
Coffee berry borer management requires intensive, integrated approaches. Cultural controls include harvesting all ripe and overripe berries promptly (beetles prefer older berries), stripping remaining berries after harvest to remove beetle breeding sites, and properly disposing of infested berries rather than leaving them on the ground where beetles can continue developing.
Biological control shows promise. Parasitoid wasps that attack coffee berry borer have been introduced and are being evaluated for effectiveness. Chemical controls must be carefully timed and applied according to strict guidelines to avoid contaminating coffee beans while targeting adult beetles when they’re vulnerable outside berries.
For coffee growers, vigilant monitoring is essential. Regular inspection of coffee berries, especially as they ripen, allows early detection of infestation. Prompt harvest of ripe berries reduces the period when beetles can attack. Coordinated area-wide management—where neighboring growers synchronize control efforts—proves more effective than isolated property-level management because beetles readily move between farms.
5. Big-headed ant
The big-headed ant (Pheidole megacephala) earned its common name from the disproportionately large heads of soldier caste members, though these represent only a fraction of any colony. This invasive species from Africa has established throughout Hawaii’s lower elevation areas, particularly in disturbed habitats, urban areas, and agricultural settings.
Worker ants display two size classes: minor workers measure about 2 millimeters long with normally proportioned heads, while major workers (soldiers) reach 3 to 4 millimeters with dramatically enlarged, heart-shaped heads equipped with powerful mandibles. The body color ranges from light brown to reddish-brown. Colonies are polygynous (multiple queens) and unicolonial (lack aggression between colonies), allowing them to reach extraordinary population densities.
Big-headed ants construct characteristic mounds of excavated soil around nest entrances, often creating numerous small piles across lawns, pathways, and garden beds. These soil mounds can be aesthetically displeasing and interfere with landscaping. The ants forage along distinct trails, often entering homes in search of food, where they become persistent nuisance pests.
Common Mistake: Many people assume big-headed ants are harmless nuisance insects. While they don’t sting or cause direct harm to humans, their ecological impact is substantial. They aggressively displace native ant species and other ground-dwelling arthropods, reducing biodiversity. They protect and farm honeydew-producing pests like aphids, mealybugs, and scale insects, indirectly harming plants by facilitating these pests.
In agricultural settings, big-headed ants protect crop pests from natural enemies, leading to increased pest populations and crop damage. They can damage seeds and seedlings directly and interfere with agricultural operations. Their presence in sufficient numbers can reduce property values and complicate farming operations.
Big-headed ants spread primarily through human-assisted transport of infested soil, potted plants, landscaping materials, and equipment. New infestations often establish when people move materials from infested to non-infested areas. They’re particularly problematic because their unicolonial social structure allows rapid population growth and territory expansion once established.
Control focuses on reducing food and moisture sources, eliminating harborage sites, and applying appropriate baits when necessary. Professional pest control may be required for severe infestations. Prevention—avoiding movement of potentially infested materials—remains the most effective approach to limiting their spread to new areas.
6. Yellow crazy ant
The yellow crazy ant (Anoplolepis gracilipes) gets its memorable name from its erratic, jerky movements and long legs that give it a distinctive appearance when disturbed. These invasive ants, originally from Southeast Asia, have established populations in Hawaii where they create serious ecological and nuisance problems.
Workers measure 4 to 5 millimeters in length with distinctively long legs and antennae. Their color ranges from yellowish-tan to reddish-brown, lighter than most ant species encountered in Hawaii. When disturbed, they move in a characteristic rapid, seemingly random manner with their bodies elevated high on their long legs—the behavior that inspired their “crazy” designation.
Yellow crazy ants form supercolonies with multiple queens and lack the aggression between nests typical of most ant species. This social structure allows them to achieve extremely high population densities. In heavily infested areas, ant densities can reach millions per hectare, creating a living carpet of ants that covers the ground, vegetation, and structures.
These ants spray formic acid as a defense mechanism and when subduing prey. While not as painful as fire ant stings, contact with yellow crazy ants can cause skin irritation and eye damage if acid contacts sensitive tissues. More significantly, their high densities make outdoor activities uncomfortable or impossible in heavily infested areas, dramatically reducing quality of life for residents.
The ecological damage is severe. Yellow crazy ants prey on native invertebrates, birds’ eggs and chicks, and other small animals, causing major declines in native fauna. They farm honeydew-producing insects extensively, leading to sooty mold growth on plants and forest decline. In some invaded areas, they’ve caused dramatic changes to entire ecosystems by eliminating key native species.
They prefer moist, undisturbed habitats but also colonize gardens, agricultural areas, and even homes. They nest in soil, under rocks, in tree cavities, and under bark—essentially any protected space. Foragers climb vegetation extensively and may establish arboreal nests far above ground.
Yellow crazy ants spread through transport of infested materials including plants, soil, mulch, equipment, and even vehicles where ants have taken temporary refuge. Their ability to form supercolonies means even a small founding population can rapidly explode into a major infestation.
Early detection and rapid response offer the best hope for control before populations reach unmanageable levels. Report suspected yellow crazy ants immediately through official channels. Control typically requires professional intervention using appropriate baits and sustained monitoring to ensure eradication.
7. Mediterranean fruit fly
The Mediterranean fruit fly (Ceratitis capitata), commonly called the medfly, represents perhaps Hawaii’s most economically significant agricultural pest. Established in the islands for decades, medfly populations require constant monitoring and suppression efforts to protect Hawaii’s fruit and vegetable industries from catastrophic losses.
Adult medflies measure 3 to 5 millimeters in body length, smaller than common house flies. They display distinctive coloring: yellowish-brown body with intricate black and white markings on the thorax, and wings patterned with yellowish-brown bands. The thorax pattern and wing markings provide reliable identification features, though small size means close examination is often necessary.
Female medflies possess a prominent ovipositor used to puncture fruit skin and deposit eggs inside. They attack a remarkably broad range of host fruits and vegetables—over 260 plant species documented worldwide. In Hawaii, they particularly threaten papayas, mangoes, citrus, tomatoes, peppers, and many other commercial and backyard crops.
Important Note: Medfly infestations create a regulatory crisis that extends beyond direct crop damage. Detection of medflies in an area can trigger quarantine restrictions that prevent fruit shipment to mainland markets. These quarantines devastate agricultural economics even when actual crop damage remains limited. The mere presence of medflies threatens Hawaii’s ability to export specialty crops that command premium prices.
The life cycle progresses rapidly in Hawaii’s warm climate. Females lay eggs inside fruit, which hatch into larvae (maggots) that tunnel through the flesh as they feed. This internal feeding causes fruit to rot and drop prematurely. Mature larvae exit the fruit and pupate in soil. Under favorable conditions, the entire cycle completes in as little as two weeks, allowing multiple generations per year.
Management requires coordinated, area-wide efforts. The Hawaii Department of Agriculture operates ongoing trapping networks to monitor medfly populations. In response to detection, they implement sterile insect technique releases—flooding areas with sterile male medflies that mate with wild females, producing no offspring and driving populations down over successive generations.
Home growers play a critical role. Harvest fruit promptly as it ripens. Pick up and properly dispose of fallen fruit immediately—never leave it on the ground where it serves as a breeding site. Bag and seal dropped fruit before disposal, or immerse it in water for several days to kill any developing larvae. Report suspected medfly activity to agricultural authorities immediately.
Fruit fly traps baited with protein lures or specific attractants can help monitor and reduce small populations around homes. However, these should supplement rather than replace proper sanitation practices and participation in official control programs.
8. Papaya mealybug
The papaya mealybug (Paracoccus marginatus) arrived in Hawaii in the 1990s and rapidly became a serious pest of papayas and numerous other crops and ornamental plants. These soft-bodied, sap-sucking insects damage plants directly through feeding and indirectly by vectoring plant diseases and producing honeydew that encourages sooty mold growth.
Adult female mealybugs measure 2 to 4 millimeters in length, oval in shape, and covered with white, powdery wax that gives them a cottony appearance. They lack wings and move slowly if at all once established in feeding sites. Males are smaller, delicate, winged insects rarely observed. The white, waxy appearance makes mealybugs relatively easy to spot on dark green foliage.
Papaya mealybugs colonize leaves, stems, fruits, and flowers of host plants. They insert their piercing-sucking mouthparts into plant tissue to feed on sap, removing nutrients and water. Heavy infestations stress plants, cause yellowing and curling of leaves, stunt growth, and reduce fruit production and quality. On papaya fruits, feeding creates blemishes that reduce marketability even when fruit remains edible.
The honeydew they excrete—a sugary waste product from sap feeding—coats plant surfaces. This sticky substance attracts ants that protect mealybugs from natural enemies. Sooty mold fungi colonize honeydew-covered surfaces, turning them black and reducing photosynthesis. The combination of direct feeding damage, plant stress, disease vectoring, and sooty mold can severely impact plant health and productivity.
Papaya mealybugs attack over 55 plant families, including critical crops like papaya, tomato, pepper, beans, hibiscus, plumeria, and many ornamentals. This broad host range means they threaten both agricultural and landscape plants throughout Hawaii.
Biological control provides the most effective long-term management. Several parasitoid wasps and predatory beetles that attack papaya mealybug have been introduced to Hawaii. These natural enemies can suppress mealybug populations substantially when present in sufficient numbers. Conserving these beneficial insects by minimizing broad-spectrum insecticide use represents an important management strategy.
Cultural controls include removing heavily infested plant parts, maintaining plant health through proper irrigation and fertilization, and avoiding excessive nitrogen fertilization which promotes succulent growth that mealybugs prefer. High-pressure water sprays can physically remove mealybugs from plants, though this requires repeated applications.
Chemical controls should be considered carefully. Insecticidal soaps, horticultural oils, and selective insecticides can reduce populations but may also harm beneficial insects. Systemic insecticides applied to soil can provide season-long protection for high-value crops but should be used judiciously.
9. Sweet potato weevil
The sweet potato weevil (Cylas formicarius) stands as the most damaging insect pest of sweet potatoes worldwide, and its presence in Hawaii severely constrains sweet potato production. This weevil attacks sweet potato plants both in the field and in storage, causing losses through direct feeding damage and by introducing secondary infections.
Adult weevils display a distinctive appearance: elongated bodies measuring 6 to 8 millimeters long, with metallic blue wing covers, orange-red thorax and head, and a prominent curved snout typical of weevils. This striking blue and orange coloration makes them relatively easy to identify when spotted, though their small size and habit of hiding in plant material means they often escape notice until damage becomes apparent.
Both adults and larvae damage sweet potatoes. Adults feed on sweet potato vines and leaves but cause relatively minor damage above ground. The serious damage occurs when females use their snouts to bore into sweet potato stems and tubers, creating oviposition tunnels where they deposit eggs. Larvae hatch and tunnel extensively through tubers as they feed, creating winding galleries throughout the flesh.
Key Insight: Sweet potato weevil damage renders tubers unmarketable and inedible. The tunneling creates entry points for bacterial and fungal infections that cause rot. Additionally, weevils produce terpenes—defensive compounds that give damaged sweet potatoes an intensely bitter taste and characteristic unpleasant odor. Even cooking doesn’t eliminate this bitter flavor. A single weevil-damaged tuber mixed with clean tubers during processing can contaminate an entire batch.
The economic impact extends beyond immediate crop loss. Because weevils infest both field and storage sites, they threaten tubers throughout the production and supply chain. Quarantines restrict movement of sweet potatoes from infested to non-infested areas, limiting market access for growers in affected regions.
Sweet potato weevils thrive in Hawaii’s warm climate, completing their life cycle in 25 to 30 days under optimal conditions. This rapid development allows multiple generations per year. Adults can fly between fields, facilitating spread, though most dispersal occurs through human transport of infested plant material.
Management requires integrated approaches. Field sanitation is critical—remove and destroy crop residues promptly after harvest, since vines and discarded tubers serve as breeding sites. Harvest tubers promptly when mature; leaving them in the ground extends vulnerability. Cure harvested tubers properly to heal minor wounds that could serve as entry points.
Crop rotation helps reduce field populations—avoid planting sweet potatoes in the same location in consecutive seasons. Consider barrier plantings or trap crops at field edges to intercept immigrating adults. Use clean, certified planting material to avoid introducing weevils to new areas.
Chemical control options exist but require careful timing and application to be effective while minimizing environmental impact. Pheromone traps can monitor populations and help time interventions.
For home gardens, raised bed or container growing provides some protection by making it harder for weevils to find and reach plants. Hill soil around plants as tubers develop to prevent cracking which creates entry points.
10. Two-spotted leafhopper
The two-spotted leafhopper (Sophonia rufofascia), sometimes called the red-banded leafhopper, has emerged as a significant pest since its detection in Hawaii in 1987. This invasive insect attacks a wide range of plants, with particular impact on native Hawaiian plants, agricultural crops, and landscape ornamentals.
Adult leafhoppers measure 5 to 7 millimeters in length with a wedge-shaped body typical of the leafhopper family. They display striking coloration: black body with two distinctive red-orange spots or bands across the wings, making them readily identifiable when viewed closely. They’re capable fliers and jump readily when disturbed, typical leafhopper behavior.
These insects feed by piercing plant tissues with their needle-like mouthparts and sucking sap. Light infestations may cause minimal visible damage, but heavy populations result in yellowing leaves, stippling, reduced growth, and plant stress. The feeding damage creates entry points for plant pathogens, and leafhoppers can vector plant diseases, though this aspect requires more research in the Hawaiian context.
A more visible indicator of leafhopper presence is the white, waxy material called wax tubes that nymphs produce. Young leafhoppers cover themselves in these distinctive white, tubular structures for protection. Accumulations of white waxy material on leaves and stems clearly indicate leafhopper activity. This waxy residue can be aesthetically displeasing on ornamental plants and may attract ants.
Two-spotted leafhoppers attack over 150 plant species from more than 30 families. Their diverse host range includes native Hawaiian plants like koa and ‘ōhi’a, agricultural crops including coffee, macadamia, citrus, and avocado, and numerous landscape ornamentals. This broad host range means they impact ecosystems, agriculture, and urban landscapes throughout the islands.
The impact on native plants raises particular conservation concerns. Hawaii’s native flora evolved in isolation without leafhoppers or similar pests and may lack effective defenses. Heavy leafhopper populations on native plants in natural areas can contribute to decline of already-threatened species.
Leafhoppers spread through flight and are readily transported on infested plant material. Their high reproductive rate and multiple generations per year allow rapid population build-up under favorable conditions.
Management approaches vary by setting. In conservation areas, reducing host plant abundance near protected sites and considering biological control agents may help reduce populations threatening native species. In agricultural settings, monitoring and properly timed insecticide applications may be necessary for high-value crops, though this must be balanced against impacts on beneficial insects.
For home landscapes, maintaining plant health through proper cultural care helps plants tolerate moderate leafhopper populations. Physical removal of heavily infested plant parts, high-pressure water sprays to dislodge nymphs, and conserving natural enemies all contribute to management. Insecticidal soaps or horticultural oils can reduce populations with less environmental impact than broad-spectrum insecticides.
Community Response and Prevention
Hawaii’s invasive insect crisis requires sustained community engagement and individual responsibility. Every resident, agricultural operation, and visitor plays a role in either facilitating or preventing the establishment and spread of these destructive pests.
Preventing Introduction and Spread
The most effective strategy against invasive insects is preventing their arrival and limiting their spread once present. When traveling between islands or arriving from the mainland, inspect luggage, vehicles, and goods for hitchhiking insects. Don’t pack fresh fruits, vegetables, or plant materials that could harbor pests. Purchase products at your destination rather than transporting them from elsewhere.
Never move agricultural materials, green waste, soil, or plants between properties or islands without proper inspection and clearance. Many invasive insects spread primarily through human-assisted transport. A single infested plant or load of mulch can introduce a destructive pest to a new area where eradication becomes difficult or impossible.
Support agricultural inspection stations at airports and harbors. These checkpoints serve as critical barriers preventing pest introductions. Report suspicious insects or plant damage through official channels including 643pest.org, a centralized reporting system for potential pest sightings.
Early Detection Matters
Most invasive insect eradication successes occur when infestations are detected early, while populations remain small and localized. Become familiar with the appearance and signs of high-priority pests. Regular inspection of gardens, crops, and landscape plants allows early detection of unusual damage or insect activity.
If you observe insects you don’t recognize, particularly if they’re present in high numbers or causing unexpected damage, collect specimens or take clear photos and submit reports to appropriate authorities. The Hawaii Department of Agriculture, County extension offices, and Invasive Species Committees across islands receive and investigate reports.
Supporting Control Efforts
When control programs are implemented in your area—whether trapping networks, biological control releases, or coordinated treatment programs—cooperation enhances effectiveness. Follow guidelines for fruit disposal during medfly suppression efforts. Allow access for monitoring activities. Avoid actions that might interfere with biological control agents like parasitoid wasps.
Economic and Ecological Stakes
The collective impact of invasive insects threatens Hawaii’s economic foundations and ecological heritage. Agriculture, tourism, property values, quality of life, and the survival of species found nowhere else on Earth all face ongoing threats from invasive insects.
The cost of inaction—measured in billions of dollars of economic losses and immeasurable ecological destruction—far exceeds the investment in prevention and early response.
The responsibility extends beyond government agencies. Homeowners managing gardens, farmers tending crops, landscaping professionals, shipping companies, tourists visiting the islands, and every resident who moves plants or materials between locations all influence whether invasive insects establish, spread, or get contained. Your awareness, vigilance, and responsible practices contribute to protecting Hawaii’s unique environment and agricultural future from these relentless invaders.
