Does hearing about West Nile scare the living DEET out of you? Have you been walking around in a mosquito net? (Please send pictures.) Then may we suggest investing in some bug repellent?
No, it’s not how we’d like to smell either (although some claim to be odorless or even smell good), but if you’re going to be in buggy areas anytime soon, it couldn’t hurt to spray yourself down. And no, this being 2014, you don’t have to buy DEET repellents if you don’t want to.
There are a number of active ingredients in various insect repellents that promise to keep bugs away. Some of the more popular, listed by the Environment Protection Agency, include:
DEET: This is the active ingredient found in many insect repellents. It repels biting pests, such as mosquitoes and ticks. Formulations registered for direct application to human skin contain 4% to 100% DEET.
Picaridin: This is a colorless, nearly odorless liquid active ingredient, which repels against biting flies, mosquitoes, chiggers and ticks. Products contain a range of 5% to 20% of picaridin.
(These are derived from such natural materials as animals, plants, bacteria and certain minerals.)
Oil of lemon eucalyptus: This is found naturally in eucalyptus leaves and twigs. Products contain a range of 30% to 40 %of the active ingredient.
Oil of citronella: This comes from dried, cultivated grasses and has a distinctive odor that masks the CO2 or lactic acid on our bodies that mosquitoes and other pests find attractive. However, oil of citronella is included on the list of chemicals that may not require EPA registration in some cases. Unless a product containing citronella is EPA-registered, it has not been subject to EPA review and EPA cannot corroborate its safety and effectiveness. These products are commonly sold as candles, and skin-applied products only offer some protection in certain circumstances. Most skin-applied products contain about 5%. citronella.
Before you use any insect repellent, particularly DEET products, be sure to read the instructions and use as directed. If you do choose DEET repellents, click here for the EPA’s guidelines and here for bug spray poisoning information from the U.S. National Library of Medicine.
Now the question: Which repellent works best? We scoured the Internet for a number of repellents and checked out the reviews so you don’t have to. While no products received A’s across the board from online reviews, some definitely stood out as fan favorites.
The active ingredient is derived from the leaves of the Eucalyptus citriodora tree. This spray is designed to repel mosquitoes for up to six hours.
Reviews: Repel received some rave reviews by users. Most found the smell to be pleasant: “Although 30% DEET was more powerful as a repellent when we were walking directly next to the swamps, the Repel Lemon Eucalyptus product was plenty effective and so much more pleasant when we were in more usual mosquito (and sand flea) territory back at our base camp,” said one reviewer. The only potential downside: Many had to reapply after a few hours; one had to do so after one hour. ConsumerSearch rated this product as the best natural insect repellent in its review.

We live in Florida and have tons of mosquitoes, but no bites with this spray! Thank you for a great, natural and SAFE product that really works.” One user who gave Burt’s Bees a poor review even recommended this repellent: “I found a great 100% natural insect repellent, non-oily, safe for kids. I use it on the dogs, smells and works fantastic. It’s by Herbaria and it’s called Citronella Mist.”

The DEET-free insect repellent uses six natural-repelling oils, including oil of soybean, oil of citronella, oil of peppermint, oil of cedar, oil of lemongrass and oil of geranium.

Reviews: Online reviewers raved about Repel 100. One even claimed: “I highly recommend this spray if you are going to the jungle.” However, with 100% DEET, people with sensitive skin should be cautious. And the smell? “Works great at making you unpleasant to everyone and yourself, as well as bugs,” one reviewer wrote.
3M Ultrathon Insect Repellent
The time-release protection means DEET is slower to evaporate and provides protection for up to 12 hours of protection; this means 3M uses less DEET. Ultrathon Insect Repellent was initially developed for the U.S. military to provide up to 12 hours of protection for troops. It contained 25% DEET.
