For many Australians insect bite first aid is an unavoidable part of outdoor life. While most insect bites and stings are harmless, some can be much more dangerous. Some insects are venomous, while all bug bites carry the risk of allergic reactions, anaphylaxis, and serious infections. With a solid understanding of insect bite first aid, you can help keep your picnic, hike, or trip to the beach safe while keeping a minor inconvenience from escalating into a medical emergency.
Common Types of Insect Bites and Stings in Australia
Insect bite first aid begins with a look at the many biting and stinging insects found in Australia. Each one has its own risks, attack triggers, and little nuances which set them apart.
Bee Stings and Wasp Stings
While similar, the main difference between bees and wasps is that bees can only sting once, leave their stinger in their victim, and then die. Meanwhile wasps can sting multiple times. Bees are also more likely to sting as a defensive measure if they feel their hive is threatened, while wasps are naturally more aggressive. Both are recognised by sharp pain and carry the serious risk of an allergic reaction.
Mosquito Bites
Mosquito bites are perhaps the most common insect encounters Australians face. While typically causing only minor itching and irritation, mosquitoes can transmit life-threatening diseases such as Ross River virus, Barmah Forest virus, and, in rare cases, Japanese encephalitis.
Ant Bites
Australian ants range from nuisance species to potentially dangerous. While the vast majority are harmless, some species, such as bull ants, fire ants, and jack jumper ants can cause severe pain. All ant bites also carry the risk of an allergic reaction.
Spider Bites
Though as arachnids spiders are not technically insects, no discussion on insect bite first aid would be complete without a look at spiders. While most are basically harmless and require only basic insect bite first aid, the redback spider and funnel-web spider are the most venomous spiders in Australia and require immediate professional medical intervention to get the life-saving antivenom.
Insect Bite Signs and Symptoms
While some bug bites are hard to miss, others are less noticeable and require a little bit of insect bite first aid knowledge to spot. Most insect bites and stings only cause mild local reactions at the bite site.
Common signs and symptoms include localised redness and inflammation around the affected area, minor pain and swelling that peaks within 24 to 48 hours, and itching that may persist for several days. Such reactions are normal and usually resolve within a few hours to days without medical intervention.
First Aid Steps Insect Bites and Stings
The first step in insect bite first aid is to slowly, calmly, and carefully move the person away from the area where they were stung or bitten to prevent further attacks.
If stung by a bee, remove the sting as quickly as possible by scraping it sideways using a fingernail, credit card, or similar firm object. Do not use tweezers as they squeeze the stinger which can inject more venom.
Regardless of the insect, wash the area with soap and water to help prevent infection. Use an antiseptic if you have one handy. Applying a cold pack wrapped in cloth to the area can reduce swelling and pain. Over-the-counter pain relief such as paracetamol manages pain, while antihistamines help reduce swelling and itching.
Allergies, Anaphylaxis, and Severe Allergic Reactions
Allergies to insect stings are one of the most common causes of anaphylaxis in Australia, with reactions to stings resulting in an average of three deaths per year. Someone experiencing a severe allergic reaction may show difficulty breathing, swelling of the tongue, throat, or face, a hoarse voice, dizziness, light-headedness, pale skin, and abdominal pain or vomiting. They may also simply collapse. If any of these signs appear, call triple zero or seek medical attention immediately.
In the meantime, insect bite first aid for anaphylaxis involves delivering a shot of adrenaline, also known as epinephrine. To use an adrenaline autoinjector remove the safety cap and place the tip of the device firmly against the outer mid-thigh (this can be done through clothing if necessary). Press down firmly until you hear a click, then hold for several seconds before removing the autoinjector. A second dose may be given after five minutes if there is no improvement.
After administering adrenaline, lay the person down on a flat surface. Do not allow them to stand or walk, and remain with them until emergency services arrive.
Prevention Tips
As with all things, prevention is the best form of insect first aid. With these simple tips you can stop bites before they even happen.
Protective Clothing
Whether hiking or just having a picnic, wear loose, light-coloured, long-sleeved shirts and long pants when heading outdoors during the summer. For hikes and long walks, wear closed-toe shoes rather than sandals, and tuck your pants into socks.
Insect Repellents
Use an insect repellent containing DEET, picaridin, or oil of lemon eucalyptus on exposed skin when spending long periods of time outdoors. However, it is important to note that this is most effective at stopping mosquitos and other small biting insects, but does not work against most other bugs.
Be Aware of Your Surroundings
Be aware of your environment and watch where you step, sit, and place your hands. Check outdoor furniture, play equipment, and picnic tables for nests before using them. If you notice insects flying repeatedly to and from the same spot, there is likely a nest nearby.
Learn First Aid for an Insect Bite or Sting
Bugs are a common nuisance in Australia, but knowing insect bite first aid can keep an itch from becoming deadly anaphylaxis. First aid for bites and stings is taught in any basic first aid course. Whether it’s learning how to better treat the symptoms of a bite, or knowing how to recognise and respond to a serious allergic reaction, knowing the proper first aid treatment for insect stings and bites, including a range of other medical emergencies, can give you peace of mind and the skills to save a life.
FAQs
Are There Natural Remedies for Insect Bites?
Sometimes. Some people find relief from natural products like aloe vera gel or tea tree oil for minor itching. However, other symptoms require first aid or for you to seek immediate medical help.
What Are the First Aid Kit Essentials for Stings?
A well-stocked first aid kit for bites and stings should include bandages, an ether-containing freeze spray for tick removal, permethrin cream, antiseptic wipes, cold packs, antihistamine tablets, and an adrenaline autoinjector if prescribed.
How To Treat a Tick Bite?
Kill the tick in place by using an ether-containing freeze spray which should cause it to drop off within minutes. Do not squeeze, twist, or pull the tick with tweezers, as this can cause its mandibles to become trapped in the wound and lead to infection. If the tick does not drop off or you cannot freeze it, leave it and seek medical help immediately.
