Are There Centipedes in Hawaii?

Are they in Hawaii?

Yes, centipedes are well established throughout Hawaii on all major islands. The most notable species is the Vietnamese centipede and a large scolopendra centipede, both introduced species that have thrived in Hawaii's warm, humid tropical environment. These larger species are more medically significant than most centipedes found on the mainland. They are found in diverse habitats throughout the islands, from lowland forests to residential areas, particularly in moist, sheltered locations. Big Island, Maui, Oahu, and Kauai all have established populations. Centipedes in Hawaii are not rare, and residents and visitors are more likely to encounter them than centipedes in cooler states. They are active year-round because of Hawaii's consistent warm temperatures. The introduction of these species to Hawaii occurred decades ago through international trade and transport, and they are now a permanent part of the islands' ecosystem. Understanding their presence is important for personal safety and comfort. For more on centipede in Hawaii, see ourHawaii centipede guide.

How dangerous is it?

Centipedes in Hawaii, particularly the larger introduced species, can deliver a painful bite that is more significant than smaller mainland centipedes. A bite from a large Hawaiian centipede may cause intense localized pain, noticeable swelling, and redness around the bite site. Pain typically peaks within a few hours and gradually decreases over one to two days. Some people report systemic symptoms such as mild swelling of the affected limb, temporary numbness near the bite, or low-grade fever, though these are uncommon. Serious medical complications are rare and very unlikely in healthy individuals. No deaths from centipede bites have been documented in Hawaii in recent history. The venom in Hawaiian centipedes is designed to subdue invertebrate prey and is not lethal to humans with modern medical care. Most bites occur when someone accidentally presses on or handles a centipede. Avoiding contact and staying aware of their presence is the best protection. Any bite should be evaluated by a healthcare provider if symptoms persist beyond 24 hours or if unusual reactions develop. You can also browseHawaii wildlife.

How to recognize one

Large centipedes in Hawaii can reach six to twelve inches in length or occasionally longer, with a strong, flattened body. The Vietnamese centipede and scolopendra species present in Hawaii are typically dark brown or reddish-brown with a streamlined body shape. Their legs are numerous, long, and relatively thick compared to smaller species. The front pair of legs is modified into venomous fangs tucked underneath. Centipedes in Hawaii move quickly when disturbed and have a predatory appearance. Smaller introduced and native centipede species are shorter, typically one to four inches, and more yellow or tan in color. All centipedes have one pair of legs per body segment, which distinguishes them from millipedes. You are most likely to find Hawaiian centipedes in dark, moist places like under leaf litter, in mulch, under logs, inside shoes or clothing left on the ground, in garages, and in basements or crawl spaces. To identify what you have found, consultCentipede in Hawaiifor more details.

What to do if you are bitten or stung

If bitten by a centipede in Hawaii, stay calm and take immediate first-aid steps. Wash the bite area thoroughly with soap and clean water to prevent infection. Soak the affected area in hot water, as warm water can help relieve pain, though water should not be so hot as to burn skin. Keep the area still and elevated if possible to minimize swelling. Remove any rings or tight bracelets on the bitten hand or arm, as swelling can occur. Do not squeeze or massage the bite, and avoid any folk remedies or home treatments like cutting, suction, or tourniquets. Over-the-counter pain relievers may help with discomfort. This is general information, not medical advice; if you are bitten, call Poison Control at 1-800-222-1222, or 911 if symptoms are severe. In Hawaii, seek medical attention if pain is severe, if swelling worsens significantly after a few hours, or if you develop any systemic symptoms. Most bites resolve within one to two days with supportive care.

How to prevent encounters

Preventing centipede encounters in Hawaii begins with reducing their access to your home and yard. Keep mulch beds and leaf litter away from house foundations and entryways. Remove dead wood, logs, and plant debris from around the property, especially near living areas. Store shoes, gardening gloves, and clothing in sealed containers or elevated off the ground, and always shake them out before wearing. Inspect bed frames and pillows occasionally, as centipedes are attracted to warm, dark sleeping spots. Seal gaps under doors and around windows using weatherstripping and caulk. Reduce indoor humidity through proper ventilation and drain plugs. Keep basements, crawl spaces, and storage areas dry using dehumidifiers if necessary. Inspect stored boxes, firewood, and garden tools before moving them. When hiking or exploring Hawaiian forests and wild areas, wear closed-toe shoes and long pants, and avoid walking through thick leaf litter with bare legs. Watch where you place your hands when climbing or sitting. CheckHawaii wildlifefor more safety information when exploring the islands.

Where in Hawaii and when

Centipedes are found on all major Hawaiian islands, including the Big Island, Maui, Oahu, Molokai, Lanai, and Kauai. They thrive in Hawaii's warm, humid tropical environment and are active throughout the year because of the islands' consistent temperature. They are most commonly encountered at lower elevations and in wetter environments, particularly in forested areas, residential neighborhoods, and coastal regions. Moist habitats like ahupuaa valleys, lush native forests, and gardens with high irrigation are ideal centipede habitat. They are nocturnal hunters and are more active at night, particularly on warm, humid evenings after rain. Dry lava fields and arid regions host fewer centipedes, but populations exist even in drier areas when moisture pockets are available. Elevation provides some protection; higher elevations on islands like Maui or the Big Island are cooler and less humid, making centipedes less abundant but not absent. In hotels and tourist areas, centipedes may occasionally be encountered indoors, especially in ground-floor rooms or older buildings.

Harmless lookalikes

Several creatures in Hawaii are mistaken for centipedes. The most common confusion is with millipedes, which have a similar body shape and many legs but possess two pairs of legs per body segment instead of one. Millipedes in Hawaii are harmless, slow-moving, and typically much smaller and lighter in color than large centipedes. Earwigs, which have pincers at their rear end, are sometimes misidentified as centipede juveniles but are much smaller and move differently. Hawaiian skinks and small lizards can be briefly confused with centipedes by the unfamiliar, but skinks have visible eyes and different body proportions. Isopods, also called pillbugs or roaches, are harmless, slow, and roll into a ball when threatened, quite different from centipede behavior. Insects like long-legged darkling beetles may appear centipede-like at a glance but have six legs, not numerous pairs. If you find a fast-moving, many-legged creature in Hawaii and are unsure, the prudent approach is to leave it alone and contact local wildlife experts.
