Recorded biting species in Nevada
Record counts come from GBIF and reflect how often a species is reported and identified in Nevada. 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 Nevada the outdoor season runs April to October; 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 8 species recorded in Nevada, 8 are active in June — the peak of the local season. The arid 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 September, at 14% of the year's total.
| Month | Species active | Notably |
|---|---|---|
| January | 1 | Bed bug |
| February | 1 | Bed bug |
| March | 3 | Honey bee, Bark scorpion, Bed bug |
| April | 6 | Honey bee, Bark scorpion, Wolf spider |

Stings rather than bites in Nevada
Honey bee, Paper wasp, Bald-faced hornet 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
- American dog tick bite — Rocky Mountain spotted fever, tularemia, tick paralysis (rare, resolves on removal)
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 Nevada
Weather does not affect everything. Bed bugs, scabies and head lice depend on people rather than season, so a bite pattern in January in Nevada points to those first.
