Mosquitoes!

“The mosquito is the state bird of New Jersey” - Andy Warhol

Mosquitoes can ruin an outdoor adventure. Many years ago I drove across country (via Canada) to my summer internship in New York with IBM. I had time to kill (the job start was delayed by one week due to paperwork) and so I had fun sightseeing. While in Edmonton, Alberta, I learned about Tar Sands and drove further north to see them. Then it dawned on me that it was June 20th, the longest day of the year and I was further north than I had ever been in my life. So I resolved to drive as near to the Arctic Circle as possible, find a campground and watch the sun not set. It was fun watching the sun move sideways near the horizon after midnight. What was not fun were the large mosquitoes! I figure the mosquitoes up north don’t have a long “warm” season to live so they are very aggressive and very hungry in the little time they have! I quickly abandoned the notion of pitching a tent and slept in my car after rolling up the windows and killing the several dozen mosquitoes that had followed me back inside!

Mosquitoes are everywhere and the traditional way to repel them is with a DEET based lotion or spray. So far as I can tell, fear over DEET is overblown. The Business Management site BNet.com, in “Is DEET safe for children”, does a nice job listing the studies that show DEET is safe. The website for Colorado Mosquito Prevention looks a lot like an advertisement promoting DEET but claims to be the product of an official state Tri-County Health Department.

However if you are DEET adverse or during an emergency, don’t have any bug spray on hand, it is possible to make your own Natural Insect Repellent Recipe as described on About.com. Many “natural” ingredients can repel bugs: citronella oil, rosemary oil, lemongrass oil, cedar oil, peppermint oil, clove oil, geranium oil, and possibly oils from verbena, pennyroyal, lavender, pine, cinnamon, basil, thyme, allspice, soybean, and garlic. But be careful – in high doses even natural oils can cause rashes or burns.

The About.com science writer, Anne Marie Helmenstine, Ph.D, recommends combining different oils to create an all-purpose bug repellent. “A good rule of thumb is to mix the repellent so it's 5-10% essential oil, so mix 1 part essential oil with 10-20 parts carrier oil or alcohol. “ For small batches mix:

• 10-25 drops (total) of essential (herbal) oils
• 2 tablespoons of a carrier oil or alcohol

Here are some essential oils to try:

• cinnamon oil (mosquitoes)
• lemon eucalyptus or regular eucalyptus oil (mosquitoes, ticks, and lice)
• citronella oil (mosquitoes and biting flies)
• castor oil (mosquitoes)
• orange oil (fleas)
• rose geranium (ticks and lice)

Mix these with one of the following base oils (for a lotion) or alcohol (for a spray):

• olive oil
• sunflower oil
• any other cooking oil
• witch hazel
• vodka

Bottom Line
“Rub or spray the natural insect repellent onto skin or clothing, using care to avoid the sensitive eye area. You'll need to re-apply the natural product after about an hour or after swimming or exercise. Unused natural insect repellent may be stored in a dark bottle, away from heat or sunlight. If you wish, you may combine the oil with aloe vera gel to change the consistency of the product.” [About.com]
