Topical Insect Repellent To Use Against Dengue Mosquitoes
While these botanical repellents may only offer limited protection times, a product registered in Australia as ‘extract of lemon eucalyptus, being acidmodified oil of lemon eucalyptus (Corymbia citriodora)’ [Mosiguard] has been shown to provide effective protection against a range of biting insects.
This product is not actually the extract from the plant but a by-product of the hydrodistillation process known as p-menthane-3, 8-diol (PMD).
This is the first plant-derived repellent to be included in public health messages issued by the Centers for Disease Control (CDC) in North America.
Correct Information on Insect Repellents
FROM: Travel Health Advisor
In view of the concerns about Zika virus and other mosquito-borne infections, … we advise the following:
Of the personal insect repellents on the market in Australia, the peak USA public health body, the Centers for Disease Control & Prevention (CDC), advises that the only repellents that are effective enough to recommend are those that contain adequate amounts of the following:
- deet (available in multiple brands in Australia)
- picaridin or icaridin (available in multiple brands in Australia)
- oil of lemon eucalyptus (OLE) or PMD (the only product available in Australia is Mosiguard)
An evidence-based review of insect repellents (Goodyer LI et al Journal of Travel Medicine 2010*) advises that there are only 3 active ingredients in insect repellents that provide enough protection (when in appropriate product concentrations) to be recommended. They are those listed above.
The CDC advice has been available for almost 10 years. A review on 1 February 2016 of health department websites in Australia reveals that there is only one federal, state or territory health department (South Australia) that even mentions PMD/OLE as a personal insect repellent choice. Many travel health clinics and other authorities also are failing to provide the same up to date information as provided by the South Australia State Health website.
When providing advice, rather than just referring to the active constituent as PMD, it is advisable that it be referred to as extract of lemon eucalyptus, and that the concentration must be 30% or greater (i.e. greater than 300g/kg). This would assist members of the public in selecting the effective products that contain the correct active ingredient and the correct concentration.

14 little known mozzie and sandfly remedies
In our quest for relief from this travellers blight we have made a few discoveries…
Firstly, we use and sell, Mosi-guard which is a natural insect repellent that has been scientifically proven to be more effective than the potent chemical repellants available, and yet it is all natural and safe — even for small children. Mosiguard works against Mosquitoes, Sandflies (Midges), Ticks and Leeches. Please find more information on the MosiGuard developers website.

Now to our other discoveries:
1. #~ Windex
Sitting at the drag races in the small town of Tom Price, in the Pilbara, we were being eaten alive by ferocious mozzies.
A neighbour told us about Windex, at the time we were keeping Windex in the vehicle all the time for when the red dust turned to mud on the windscreen, so we were rapt to find out that it was an excellent way to neutralise the toxin from those insect bites (including March flies).
The march flies were particularly vicious, and if you reacted (as I did) you could get a wildly itchy patch some 8cm across.
I had never heard of or experienced that before, where I come from march flies leave a bite not much worse than a mozzie.
So we were covered in bites, applied the Windex liberally, the toxin was gone, no worries – hardly any bites the next day.
2. #~ Deodorant
This is great in an emergency. I discovered deodorant on a trip to Sumatra, Indonesia. It seems to have some power to neutralise the bites, but mainly it stops the itch by sealing the bite from exposure to the air
3. #Vinegar
Aah the wonders of vinegar – not only is it a powerful mould killer, cleaner, neutraliser of jelly fish poison and fabric softener but vinegar is an excellent neutraliser of biting insect toxins. It is great for mozzies, sandflies, March flies- the March fly bites will sting for a second as they actually give you a little cut, but it is worth it if you react badly (my bites last for days).
4. #Wine
Yes, good old wine. On my first night in Kuranda near Cairns, on the way to a house sit I was staying at a nice Bali style resort. Sitting at the poolside restaurant I was spiked by a hairy caterpillar; it was tiny, just about 15mm long I flicked it away but immediately came up in big red, extremely itchy welts where ever it had landed on me. I asked the waiter if they had anything to put on it or knew what to do. His eyes went wide and he hurried off to see what he could find, never to return. My instinct was to grab for the vinegar but since I didn’t think they would appreciate me breaking into the kitchen I just dipped my finger into the wine, and spread it over the welts. It worked a treat! The marks were gone the next day. Later I heard from the locals that these hairy caterpillars left little spikes in you that itched for weeks, so I counted myself very lucky that I had neutralised the toxin before it got a chance to take hold.
5. *Clothing
This shouldn’t be little known – not much is going to bite through clothing, though they will go under and around. Your average weight material will protect you from mozzies, but even thin material will protect you from sandflies and less vicious mozzies while having the added bonus of reducing sunburn. I like that light indian cotton such as the kurta shirt for coolness and some protection, particularly at dawn and dusk. I am no scientist but I don’t get why you would need to impregnate cloth with insect repellent when the cloth forms a physical barrier anyway, and I notice that the fine print says that you still need to use repellent on exposed bits! If it is hot you want to use insect repellent so that you can expose bits and cool off! On that vein I don’t get SPF clothing, unless your shirt is as thin as these kurta’s it will shield you from the sun anyway! Aka Slip Slop Slap!
6. *Wind – Fan
I don’t find it enough by itself but those less allergic than me are convinced that the fan over the bed is enough to keep the sandflies at bay.
7. *Baby Oil
When I arrived in the tropics the locals advised us to use baby oil, since we would be living in the open air – our houses don’t have glass on the windows, or even fly screens, this is because you need to let as much air flow through as possible, to cool you down and to stop everything from going mouldy in the went season. This does stop the sandflies by creating a physical barrier that they can’t bite through, though it only lasts an hour or so as it soaks in or is diluted by sweat, I also found that it was hard not to wipe it off, especially if I already had bites that cried out to be scratched, adding lavender or tea tree oil helped, as a repellent and to sooth the existing bites. Though I did feel pretty yuk covered in oil.
8. *Avon Skin-so-soft
If you do a search on the web for sandfly or midge repellents you will come up with Avon Skin-so-soft, I haven’t tried it but have read many glowing reviews, stories of use by UK Special Forces. It seems it works on the same principle as baby oil, providing an oily coating to the skin that the sandfly or midge urine does not penetrate. I also read scientific studies that showed that it was less effective than most other products, and a comment on an expat forum commenting that the midges over here were a completely different entity to those that our British counterparts were dealing with.
9. #~Calamine
Well, when I was a kid it was not ‘little known’ it was ‘the thing to use’ everybody had Calamine in the cupboard. It is still amazingly effective stuff, even if a bit embarrassing to go out in public showing off white/pink blobs that yell – Hey! I am new in town! Still if I am staying in, I love the stuff, dab it on thickly to form a seal, this is what gave me the idea for the deodorant in Sumatra. I don’t think it neutralises the toxin as well as some of the others though.
10. *#~Tea tree oil
Great for neutralising the toxin, soothing the bites, and gives some protection as a repellent. The thing about sandflies is that you have to have repellent on every inch, they are not deterred by just the smell of it as mozzies are. It is great for mould as well. Locals at Kuranda, the mould capital, say that bleach doesn’t kill off the spores but Tea Tree, Vinegar and Clove oil do, they are kinder to fabric too.
11. *#~Lavender
We had a gig house-sitting a lavender farm in Queensland with a horse and 2 chooks. They put us onto lavender oil for bites. We didn’t have to worry about sandflies but lavender oil is great for neutralising and soothing mozzie bites. Here in the tropics I did try it with the baby oil and found it gave it a boost as a repellent and soothed my bites as well. Lavender is a hardy plant that you can grow around your home to keep the blighters at bay.
12. #Take a shower
This works for sandflies, as the toxin is in the urine they leave on your skin you can wash it off. I find if I feel some bites before I have put repellent on, if I have a shower as soon as I can it reduces the number and severity of the bites.
Since arriving in the tropics and trying so many different products, including the mainstream insecticides we have found what we were looking for!
13. #~Rainforest rejuvenation
If you have been bitten, this product is amazing at neutralising the toxin and relieving the itch – it is a combination of natural rainforest oils and sea salt made in Kuranda, near Cairns Qld.
14. *#~Mosi-guard – Lemon Eucalyptus
Now this is the most amazing product; when I lived the easy life in southern NSW and Canberra natural insect repellants were my preferred option, they worked fine for me. But once I left the safety of civilised society and took off to explore wild and wonderful horizons, the insects just got desperately persistent they were not to be deterred! At one of our first stops the insects were so persistent that even with commercial tropical strength repellant dabbed on my face and surface spray on my hat they hovered just inches away waiting for any chance.
We found Mosi Guard on the net, we had trouble finding a retailer, we did find one that had a couple they had forgotten about and bought a couple to try, we were amazed. It was everything the manufacturers website said it was. It was at least as effective than the DEET products at repelling the biting insects, but at the same time it soothed the bites and neutralised the toxins! So unlike the mainstream insect repellents you don’t rub it off scratching at your bites, even if you do rub or scratch or sweat it doesn’t just sit on the surface of your skin so it isn’t such a drama, and it is so nice to use on your skin, it smells lovely and fresh – of lemon eucalyptus, not chemicals and perfumes. So we bought a box of 12.
Our neighbours came to call, they have lived in this area for years, we gave them some Mosi Guard to try and were amazed as well, they came back the next day to buy some off us.
The same story with another set of neighbours.
So we decided to start selling it ourselves, we had been looking for products to sell online that are useful to people travelling in remote places as we do.
Insect bite remedies work in 3 different ways,
* They stop the insect biting – apply before you are likely to be bitten
# They neutralise the toxin – apply immediately you have been bitten
~ They relieve the itch – apply after the bites have developed
We have moved to Mareeba
After living for nearly 4 years in paradise, we have moved to Mareeba (near Cairns)
I am selling at the local markets (calendar to come).
I also have a pump spray for sale locally only (as we cannot freight it due to Aust Post regulations)
Calamine
Calamine is a mixture of zinc oxide (ZnO) with about 0.5% ferric oxide (Fe2O3). It is the main ingredient in calamine lotion and is used as an antipruritic (anti-itching agent) to treat mild pruritic conditions such as sunburn, eczema, rashes, poison ivy, chickenpox, and insect bites and stings. It is also used as a mild antiseptic to prevent infections that can be caused by scratching the affected area, and an astringent to dry weeping or oozing blisters and acne abscesses.

Sandflies (Midges)
Sandflies (as we know them in Australia) are actually Biting Midges and are members of the insect family Culiocoides. Over 270 species of Culiocoides occur in Australia but only three main species cause havoc and itchiness in humans.
Their habitats are mangrove swamps and tidal flats, coastal lagoons and estuaries. They don’t like wind very much so calm still days are the worst, although if a light wind is coming from the direction of their habitat, we have found they still bite.
The Byron Shire council has a good article on their website about “Why are biting midge bites so unpleasant?”
“The anatomy of their feeding mechanism means that (unlike mosquitoes) they leave a large raised mark on the skin that is filled with damaged tissue and saliva (containing anticoagulants). This can cause certain individuals repeatedly exposed to their bites to become ‘sensitised’ and trigger allergic responses. The direct impact on human health and wellbeing caused by midges is due to the allergens in midge saliva. These biting insects are an annoyance to humans, but are not likely to transmit disease.”
Sandflies do tend to attack arms and legs more than bodies, so protecting these works well.
We lived in Cape York at sandfly heaven for 4 years. While there we covered feet, legs, hands and arms with Mosiguard early in the morning and about 3 in the afternoon
Anti-histamines do help with people who get allergic reactions to sandfly bites (but you should get your doctors opinion before you do this).
Mosquitoes
Mosquitoes (known as mozzies in Australia) are found almost all over the world. There are over 2,500 species world-wide. Mosquitoes are estimated to infect over 700 million people annually (worldwide) and cause about 2 million deaths annually.
In Australia we have about 300 species but less than 20 of these are of worry to human health. We don’t have malaria in Australia and there are very few (if any) mosquito caused deaths. The main diseases in Australia that mosquitoes do infect humans with are Ross River Fever, Barmah Forest Virus, Dengue Fever and Australian Encephalitis. The symptoms can vary from mild to severe and sometimes debilitating.
However most people do find mosquito bites annoying, and it is wise to try and NOT get bitten.
There are a multitude of remedies and repellents available. DEET based solutions are effective but DEET is a synthetic chemical solvent. The Rid website says to “avoid situations where leaks or spills of this product could contact and damage spectacle frames,contact lenses, soft plastics, PVC, vinyl, leather, some clothing dyes, timber fittings, painted and polished surfaces.
The DEET in RID softens these materials, and the damage cannot be repaired. ”
The mosiguard website states “Deet is readily absorbed into the skin which can lead to problems, especially in young children.”
Mosiguard has been tested extensively and recently the London School of Hygiene and Tropical Medicine tested mosiguard against some of the most popular repellents and found that Mosiguard was as “effective as the strongest available deet repellent over an eleven hour period“.
