Bites and Stings

29 June 2010

We all find the itch of a mosquito bite, or the pain of a bee sting very unpleasant, yet for some it can trigger an allergic reaction. Fortunately severe allergic reactions are uncommon, but even a mild reaction can be very uncomfortable.

Bites

March flies and mosquitoes cause nasty, itchy bites, while caterpillars cause severe irritation from touching their spines. Fortunately, allergic reactions are rarely serious, even if the swelling is large.

Stings

Allergies to venoms from stinging insects are a common cause of serious allergic reactions in Australia. The usual culprits are:

  • Honey bees
  • European wasps and paper wasps
  • Jack jumper ants, a very aggressive black bull-ant with a ‘hopping' walk found in SE Australia
  • Green ants, found in Queensland
  • Native Australian bees

Managing allergic reactions to stings

If you have ever had more than just a small reaction to a sting, such as hives on another part of your body, see your doctor for an allergy check up. You may need an allergy action plan, which helps you recognise the seriousness of a reaction and tells you what to do in response.

Prevention is better than cure

  • Bites from midges and mosquitoes are best avoided by covering up as much as possible. Avoid being outdoors in the early morning or at dusk, and use an insect repellent containing DEET.
  • Nightly checks for ticks may help. If someone with a known tick allergy is bitten, seek medical help before removing the tick as allergic reactions often occur when the tick is removed.
  • Honey bees normally only sting in self-defence, so don't confusing them by pretending to be a flower! Minimise perfumes, and avoid bright colours and floral prints. White clothing is good, as are muted colours.
  • Wasps are more aggressive than bees and are attracted to food and drink. Avoid provoking them and don't drink "blindly" from drink cans outdoors.
  • Cover up. Stings often occur on bare feet. Allergic people should wear shoes outside, and gloves, long sleeves and long pants when gardening.
