When do insect bites peak in Australia?
Across 49,302 verified records for Australia, biting and stinging activity concentrates in March, April, October — April alone accounts for 13% of sightings, and July is the quietest month of the year. Australia is in the southern hemisphere, so this runs opposite to the European and North American season.

What actually bites you in Australia
Australia is where standard bite advice most often stops being correct. Tick removal guidance here is the reverse of the American approach: freeze the tick in place rather than pull it, because disturbing a paralysis tick can trigger a surge of saliva. Pressure immobilisation bandaging, correct for snake bite, is explicitly wrong for redback bites. And the paralysis tick is the main local cause of mammalian meat allergy, which begins months after a bite that was long forgotten.
| Species | Pattern | Where on body | Records | Peak here |
|---|---|---|---|---|
| Redback spider bite | single site | hands, buttocks | 7,169 | January, April |
| Paralysis tick bite | single | scalp, behind the ears | 1,324 | August to November |
| Aedes mosquito bite | several bites, frequently on ankles and lower legs | ankles, lower legs | 632 | May, August |
| Honey bee sting | single | feet — bees are often stepped on in clover, hands | 33,785 | March, April, October |
| Yellowjacket sting | single or several — this wasp can sting repeatedly | hands, face | 4,229 | March to May |
| Paper wasp sting | usually single | hands, head | 752 | November to March |
| Flea bite | clusters of three or four, or short irregular groups | ankles, shins | 519 | January, May, December |
| Fire ant sting | multiple stings in a ring or cluster — the ant grips and pivots | feet, ankles | 277 | May, July |
| Mosquito bite | single bumps scattered over exposed skin | ankles, lower legs | 252 | March, April, November |
| Bed bug bite | lines or zigzags of three or more — the classic "breakfast, lunch and dinner" | arms, shoulders | 169 | March, November |
| Scabies rash | symmetrical, in finger webs, wrists, waistline, armpits and groin | finger webs, wrists | 126 | March, June, October |
| Head lice bites | concentrated behind the ears and at the nape | scalp, behind the ears | 59 | January, April, November |
| Black widow spider bite | single site | hands, forearms | 8 | — |
| Carpenter ant bite | single or a few | hands, arms | 1 | — |
Honey bees usually top records like these because they are the most photographed insect on earth, not because they sting most often. Read the column as "definitely present here", not as a ranking of risk.
What is different about Australia
Southern-hemisphere season, plus first-aid advice that genuinely differs from the rest of the world. Copying American guidance here can make things worse.
Species linked to illness here
- Paralysis tick bite — tick paralysis, tick-induced mammalian meat allergy (alpha-gal), Queensland tick typhus
- Aedes mosquito bite — dengue, Zika, chikungunya, yellow fever
- Flea bite — murine typhus (Gulf Coast, California, Hawaii), cat scratch disease bacteria carried between cats, flea tapeworm (mainly in children who swallow a flea)
- Mosquito bite — West Nile virus, La Crosse encephalitis, dengue (Gulf Coast and Southwest, local cases), chikungunya (rare, travel-linked)
- Scabies rash — secondary bacterial skin infection is common from scratching
Most bites transmit nothing. What matters is the follow-up: note the date, and report any fever or expanding rash in the weeks afterwards to a clinician, mentioning the bite and where you were.
Stings rather than bites
Honey bee, Yellowjacket, Paper wasp, Fire ant, Carpenter ant are recorded in Australia. Stings differ from bites in one way that matters: they can cause anaphylaxis in sensitised people, and that risk does not depend on how mild previous stings looked. Anyone who has had a severe reaction should carry an adrenaline auto-injector.
Year-round regardless of season
Weather does not affect everything. Bed bugs, scabies and head lice depend on people rather than temperature, so a bite pattern in the middle of Australia's quiet season points to those first — see what is biting me at night.
Seek medical care if
Call emergency services now for difficulty breathing, swelling of the lips, tongue or throat, dizziness or fainting, or hives spreading away from the bite.
- difficulty breathing, 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 that is getting worse rather than better after 72 hours
