Yes, Hawaii has ticks, though your risk is usually lower than in many mainland regions. Introduced ticks can affect dogs, livestock, and people, especially near homes, kennels, yards, and vegetation.
For most visitors, the main concern is preventing bites and checking your clothing, skin, and pets after outdoor activities. You are most likely to encounter the brown dog tick around residences and animals.
Local tick-borne diseases are a bigger concern for dogs than for people.
The Short Answer
Ticks live across the Hawaiian Islands, including Oahu, the Big Island, Maui, Kauai, Lanai, and Molokai. County surveillance has not found several major mainland species established in Hawaii.
The brown dog tick is commonly found around homes, kennels, and dogs.
Why Tick Exposure Is Usually Pet- and Property-Related
The brown dog tick, Rhipicephalus sanguineus, often lives around dogs. It can persist in kennels, yards, cracks, and indoor areas.
Dogs can spread ticks through contact or by moving between properties. Dog care and household prevention are especially important.
People can still pick up ticks while walking through vegetation. A casual beach visit or time spent at developed urban attractions is less likely to create exposure than contact with an infested dog or yard.
Year-Round Activity in a Tropical Climate
Hawaii’s warm climate supports tick activity throughout the year. You should not rely on a short mainland-style tick season.
If you own a dog or spend time in vegetation, stay alert year-round.
A recent Hawaii tick-season analysis recommends year-round awareness because introduced ticks can pose risks to pets.
Places Where Encounters Are More Likely
You are more likely to encounter ticks in dense vegetation, tall grass, hiking trails, wooded areas, dog parks, and unmanaged yards. Risk can vary by property and animal activity in Honolulu County, Hawaii County, Kauai County, and Maui County.
On Oahu, areas around Ewa Beach and Kailua include residential or trail environments where checking pets makes sense. Trails near the Na Pali Coast and other natural areas on Kauai also warrant routine checks.
Species Found Locally and Mainland Ticks to Distinguish
You are most likely to deal with different tick species than the deer tick, American dog tick, lone star tick, Gulf Coast tick, and other mainland species. County records describe distribution, but “not established” means no confirmed population in surveillance, not that a single tick can never arrive.
Brown Dog Ticks Around Homes and Dogs
The brown dog tick is reddish-brown and narrow, usually lacking the ornate markings seen on several mainland ticks. It can complete its life cycle indoors and may spread Rocky Mountain spotted fever or canine diseases.
Ask a veterinarian about reliable flea and tick control if your dog spends time in kennels, dog parks, yards, or homes with recurring tick sightings.
Spinose Ear Ticks Near Livestock and Animal Ears
The spinose ear tick, Otobius megnini, is associated with livestock and animal ears. Its immature stages can irritate animals.
Ranchers and animal owners should check ears and seek veterinary help if an animal shows head shaking, rubbing, pain, or discharge.
Ticks Not Established in Hawaii
Mainland species such as the deer tick (blacklegged tick, Ixodes scapularis or Ixodes pacificus) are not established in Hawaii. The American dog tick, Dermacentor variabilis; lone star tick, Amblyomma americanum; Gulf Coast tick, Amblyomma maculatum; Asian longhorned tick, Haemaphysalis longicornis; and Rocky Mountain wood tick are also not established according to available surveillance.
You should treat identification claims cautiously because ticks can arrive on animals, luggage, or transported goods. The CDC’s tick distribution information explains why species ranges matter when you assess disease risk.
Lyme Disease and Other Health Concerns
Lyme disease is not considered endemic in Hawaii, and the local Lyme disease risk is very low. Tick bites can still cause irritation, allergic reactions, or infection.
Dogs may face illnesses such as canine ehrlichiosis.
Why Local Lyme Disease Risk Is Very Low
Lyme disease requires infected Borrelia bacteria and a competent transmitting tick. The blacklegged ticks linked to most U.S. Lyme transmission do not live in Hawaii.
Reported Hawaii cases are generally linked to exposure elsewhere.
The Hawaii Department of Health Lyme disease guidance notes that Lyme disease spreads through infected tick bites and is not transmitted person-to-person. Tell a clinician about recent mainland travel if you develop symptoms after possible exposure.
Symptoms That Need Prompt Medical Attention
Seek medical advice for an expanding rash, fever, chills, headache, unusual fatigue, muscle or joint aches, facial weakness, or other symptoms after a tick bite. These signs can overlap with Rocky Mountain spotted fever (RMSF), ehrlichiosis, anaplasmosis, babesiosis, or unrelated illnesses.
Do not wait for a classic bull’s-eye rash. Keep a record of the bite date, location, travel history, symptoms, and any tick you safely remove.
Early evaluation can guide testing and antibiotic therapy when appropriate.
Canine Diseases and Veterinary Warning Signs
Dogs can develop canine ehrlichiosis and other diseases after tick exposure. Contact your veterinarian if your dog develops fever, lethargy, reduced appetite, swollen lymph nodes, bruising, pale gums, lameness, or unusual bleeding.
A veterinarian can recommend testing and treatment based on symptoms and exposure. Do not give your dog leftover antibiotics or human medication without veterinary instructions.
Prevention, Tick Checks, and Safe Removal
Simple tick prevention lowers your risk on trails, around yards, and near animals. Combine appropriate repellent, clothing choices, routine tick checks, and veterinary flea and tick prevention.
Protecting Dogs, Bedding, and Indoor Spaces
Use a veterinarian-recommended flea and tick prevention product consistently, including during Hawaii’s warm months. Check your dog’s ears, collar area, toes, armpits, and groin after outdoor time.
Inspect bedding, crates, and resting areas. If you find repeated brown dog ticks indoors, do not rely on a single bath or spray.
Ask your veterinarian or a qualified pest professional about treating the dog and property together.
Reducing Exposure on Trails and Around Yards
Stay on maintained paths and avoid brushing against tall grass or dense vegetation when practical. Wear light-colored clothing, tuck pants into socks, and use an insect repellent containing DEET or picaridin on exposed skin according to the label.
For longer outdoor activities, permethrin-treated clothing can provide additional protection. Do not apply permethrin directly to your skin, and keep treated products away from cats until completely dry.
Removing an Attached Tick Safely
Use fine-tipped tweezers to grasp the tick as close to your skin as possible. Pull upward with slow, steady pressure.
Clean the bite and your hands with soap and water or an alcohol-based cleanser.
Do not burn, crush, smother, or twist the tick while it is attached.
Save the tick in a sealed container or take a clear photo if identification may help.
Contact a clinician if symptoms develop after you remove the tick.
