Best Natural Mosquito Repellents
If you prefer to use natural bug repellents rather than chemical or DEET based mosquito sprays, you might like to look at the selection here.
However, it is true to say that 'natural' does not necessarily mean 'safer' as many people are allergic to natural oils.
The US Environmental Potection Agency have only passed 6 mosquito repellent sprays for topical use. Three of them are chemical (DEET, Icaridine and IR3535) and three are plant based and are discussed below.
Please follow the instructions on the label when applying any of the products listed here, as they can be extremely irritating to the eyes, and have caused skin irritations in some sectors of the population, especially children.
Lemon eucalyptus bug repellent
Lemon eucalyptus comes from the corymbia citriodora tree found growing up to 50 metres high in north eastern Australia and in China. It's other names are blue-spotted gum, lemon-scented gum and lemon eucalyptus.
The essential oil obtained from the lemon eucalyptus is citronellal, while its unrefined oil is used in perfumery and insecticides.
These oils are normally obtained from the leaves of this tree and are reportedly widely to be a highly effective alternative to chemical-based insecticide sprays.
Studies have also shown that lemon eucalyptus oils, when added to water containing mosquito larvae, prevent the larvae from emerging as adults, depending on the strength of the oil added.
The active ingredient in lemon eucalyptus is named as PMD (p-menthane-3,8-diol) and is one of only three plant-derived products endorsed by the US Centers for Disease Control and Prevention as being effective against the West Nile Virus, which is spread by mosquitoes.
The other two named are Citronella and Nepetalactone.
It is also effective against biting flies and gnats.
Citronella is another non-chemical natural bug repellent recommended by the EPA for general use.
It is derived from two Asian grass plants, Cymbopogon winterianus and Cymbopogon nardus which are similar to those of the Lemon Grass family.
These plants can become invasive and so are not recommended for home growing.
Like eucalyptus oil, products containing citronella are not recommended for children under 3 years of age in case they give rise to irritation.
However, it is entirely at your discretion if you care to put a small amount on your child for their protection, and observe them carefully for adverse effects. Only some children are irritated by this product.
Citronella when used on the skin needs re-applying frequently, every 30 minutes or so to maintain its effectiveness.
Mosquito candles are frequently made from citronella that is derived from the lemongrass plant. I have not found them to be of any use whatsoever and believe it to be nothing more than a marketing ploy to get you to buy the citronella candles.
Lemon Grass Mosquito repellent
Lemon Grass (Cymbopogon citratus) may have a lot of uses, but it has never proven its effectiveness as a mosquito repellent.
The active ingredients in lemongrass are geraniol and citronellol which are widely used in soaps and household disinfectants because of their antiseptic properties.
Garlic mosquito repellent
Garlic mosquito repellent is widely used for spraying wide areas to keep the population of mosquitos and other insects down.
However, there is no evidence that using a garlic spray on your body will deter mosquitoes, so it would probably be better for you to stick with a DEET-based spray if you are likely to get bitten or have a high incidence of the West Nile Virus in your area.
It will do you no harm to eat garlic so that it seeps through your pores. It may or may not deter mosquitoes (some people swear by this method), but because garlic is good for you in so many other ways you are bound to derive some benefit by doing so.
Unfortunately, it may deter other people from coming close to you.
Catnip mosquito repellent
Catnipis reputed to make a better insecticide than DEET.
This is because it was discovered in 2001 that the active ingredient in catnip, nepetalactone, is actually 10 times more effective than DEET at repelling mosquitos.
In 2009, EPA passed a product made by Dupont containing largely nepetalactone derived from the catnip plant, nepeta cataria. This was the first new insect repellent to be registered in 8 years.

Hot Off the Press
According to a Spanish television program, to deter mosquitoes put 1 tablespoon of apple cider vinegar in a small bowl. Add a handful of cloves and leave for 1 day to soak.
Apply to skin (in evening, as that is when mosquitoes bite most), and apparently mosquitoes stay away as they don't like this mixture.
