Recorded biting species in Hawaii
Record counts come from GBIF and reflect how often a species is reported and identified in Hawaii. A guide to what is plausible here, not a census.
Narrowing it down in three questions
- Where on your body? Below the knee in clusters points to fleas or chiggers. Uncovered skin — arms, shoulders, neck — points to bed bugs or mosquitoes. Along a sock line or waistband is close to diagnostic for chiggers.
- How are they arranged? A line or zigzag of three or more suggests bed bugs. Scattered single bumps suggest mosquitoes. A curved group with white pustules the next day means fire ants.
- Indoors or outdoors, and when? In Hawaii the outdoor season runs January to December; the indoor species run all year — see what is biting me at night.
- Breathing trouble, or swelling of the lips, tongue or throat after a sting
- A red area that is spreading, hot and painful — especially with a red streak
- Fever, chills or feeling generally unwell in the days or weeks after a bite
- An expanding rash appearing 3 to 30 days after a tick bite
- A bite getting worse rather than better after 72 hours

Bite season month by month
Of the 3 species recorded in Hawaii, 3 are active in March — the peak of the local season. The tropical climate here is what sets those boundaries: species that need warmth disappear at the edges of the year, while the indoor ones do not care. By sighting records the busiest month here is May, at 15% of the year's total.
| Month | Species active | Notably |
|---|---|---|
| January | 1 | Scabies |
| February | 1 | Scabies |
| March | 3 | Honey bee, Flea, Scabies |
| April | 3 | Honey bee, Flea, Scabies |
| May | 3 | Honey bee, Flea, Scabies |
| June | 3 | Honey bee, Flea, Scabies |
| July | 3 | Honey bee, Flea, Scabies |
| August | 3 | Honey bee, Flea, Scabies |
| September | 3 | Honey bee, Flea, Scabies |
| October | 3 | Honey bee, Flea, Scabies |
| November | 2 | Flea, Scabies |
| December | 1 | Scabies |
Stings rather than bites in Hawaii
Honey bee are recorded here. Stings differ from bites in one way that matters: they can cause anaphylaxis in sensitised people, and that risk does not depend on how bad previous stings looked. Anyone who has had a severe reaction should carry an adrenaline auto-injector.
Species associated with illness here
- Flea bite — murine typhus (Gulf Coast, California, Hawaii), cat scratch disease bacteria carried between cats, flea tapeworm (mainly in children who swallow a flea)
- Scabies rash — secondary bacterial skin infection is common from scratching
Most bites from these species transmit nothing. What matters is the follow-up: note the date of the bite, and report any fever or expanding rash in the following weeks to a clinician, mentioning the bite explicitly.
Year-round in Hawaii
Weather does not affect everything. Bed bugs, scabies and head lice depend on people rather than season, so a bite pattern in January in Hawaii points to those first.
Common questions
What bites are most common in Hawaii?
By verified sighting records, the most frequently recorded biting species in Hawaii are honey bee, flea, scabies.
When is bite season in Hawaii?
Broadly January to December, driven by the tropical climate. Bed bugs, scabies and head lice are year-round because they do not depend on weather.
Something bit me at night in Hawaii — what was it?
Overnight bites most often mean bed bugs, fleas or mosquitoes. Lines of welts on uncovered skin suggest bed bugs; clusters below the knee suggest fleas.
