Natural insect repellents have a tendency to provide coverage for a shorter amount of time than chemical mosquito repellants so. But since their coverage is so much safer, than using Deet or other harmful chemicals. you may find it worth the extra effort applying it more often.
DEET is a nasty chemical that can cause terrible rashes, eye irritation, swelling and even worse problems. The worst problems found to be caused by Deet are unusual but they HAVE happened, they include- brain swelling in children, low blood pressure, anaphylactic shock and there has even been a report of a death.
For best results you should reapply the natural repellants often-probably about every 30 minutes or so but it can be worth it to avoid the nasty side effects of chemical repellants.
Make your own insect repellent sprays by simply combining vodka, rubbing alcohol, witch hazel, or olive oil with one of the following essential oils:
Citronella (also known as rose geranium) is the most effective essential oil against mosquitoes
Thai lemon grass (Cymbopogon citratus)
Clove oil works well but can be a skin irritant so I would use it more on clothing
Eucalyptus
Lemon grass
Castor oil
Tea tree oil
Peppermint
Lavender
Cedar
Lavender
Cinnamon oil
Castor oil
You should stick with around a 10-to-1 alcohol to essential oil ratio. This means use 10 Tablespoons of vodka or witch hazel to every Tablespoon of essential oil. Be sure to shake well before each use.
Store in a dark bottle, away from heat or sunlight. If you are pregnant or nursing please do not use any mosquito repellent, natural or otherwise, until after you’ve gotten the ok from your physician. Don’t go overboard with essential oils as they are potent and could cause skin irritation, or some type of a reaction, if you use too much.
