mosquito repellent

I have been using the following recipe to repell mosquitos:

Garlic Tea. This works! 2 heads of garlic, chopped 2 peppers (the hotter the better e.g habinero, 1 cup of vegetable oil, 1 tbsp of dishsoap --dump this into a gallon jug, fill the rest with water and let it set in the sun for a day or so. Spray at a 1/4 cup per gallon on the lawn, bushes, house, trees... I spend about 10-15 hours outside per week, and I've gotten bit less than 5 time ALL YEAR...

The following information is taken from http://www.garlic-central.com/mosquito.html

There is a long history of using garlic to get rid of many insects, from slug to mosquito. In particular garlic has a reputation for protecting people from mosquito bites - some think that this could be the origin of the belief that vampires are scared of garlic. There are a number of commercial garlic sprays on the market, these effectively coat an area and produce a natural mosquito barier.
Garlic is more effective at repelling some species of mosquitoe than others. For this reasons many of the commercial preparations available include a number of different repellent ingredients such as catnip and soy as well as garlic.
Why Does Garlic Repel Mosquitos?It's not clear why garlic should be an effective mosquito repellent. It would seem that the powerful compounds such as allicin which garlic releases are inimical to mosquitos. They have therefore evolved to avoid garlic. Another possibility is that the strong smell of garlic overwhelms the mosquito's sense of smell and prevents them from finding their prey (us!).
Whatever the mechanism, garlic's ability to repel a variety of pests has been proven scientifically. Its effect against mosquitos specifically is less well documented however there is much anecdotal evidence to support it.
If you wish to protect an entire area such as your garden, you could treat it with one of the commercially available garlic based sprays you can buy. For individuals, studies (1) have shown that coating the body with a jelly based compound including garlic can keep mosquitoes away for some time. Obviously such a method, whilst effective against bites, has fairly major social side effects! (Warning: the allicin in garlic is very strong and can result in skin problems and allergic reactions. Consult your doctor
Fortunately you probably don't have to go that far. There is strong anecdotal evidence that simply consuming more garlic can help to prevent mosquito bites.
This is not simply a case of mosquitos being averse to garlic breath! If you eat a large amount of garlic then it actually seeps out through the pores of your skin. Some people think that this invisible layer of garlic oil might create a natural barrier cream. Any mosquitoes which do find you will think twice before taking a bite.
Given the possible dangers from mosquito bites (West Nile virus etc) I don't recommend you rely on garlic alone!
