Insect Repellent: Ratings of Sources

1. Insect repellents, Editors of, Last updated: March 2017
In this free guide, Consumer Reports evaluates 16 insect repellants by putting testers' treated arms into a cage filled with mosquitoes and counting the number of bites they get every five minutes. They also test against ticks by placing five uninfected ticks on the tester's arm to see how many enter the treated area. Six products, with a variety of active ingredients, perform well enough to earn recommendations.
2. Journal of Insect Science Efficacy of Some Wearable Devices Compared with Spray-On Insect Repellents for the Yellow Fever Mosquito, Aedes aegypti (L.) (Diptera: Culicidae), Stacy D. Rodriguez, Hae-Na Chung, Kristina K. Gonzales, Julia Vulcan, Yiyi Li, Jorge A. Ahumada, Hector M. Romero, Mario De La Torre, Fangjun Shu, and Immo A. Hansen, Feb. 16, 2017
A team of scientists tests five mosquito repellent sprays against alternative pest-repelling methods such as bracelets, wearable devices, and a citronella candle. A cage full of mosquitoes is placed in a wind tunnel, a volunteer sits a short distance upwind, and the scientists measure how many mosquitoes are attracted toward the volunteer. A concentrated DEET-based spray works best, but one clip-on device is also effective.
3. Journal of Insect Science The Efficacy of Some Commercially Available Insect Repellents for Aedes aegypti (Diptera: Culicidae) and Aedes albopictus (Diptera: Culicidae), Stacy D. Rodriguez, Lisa L. Drake, David P. Price, John I. Hammond, Immo A. Hansen, Oct. 5, 2015
A team of scientists test seven commercial mosquito repellents, along with two fragrances and a vitamin B patch, by releasing mosquitoes into a sealed chamber with a tester's treated hand. Products with DEET are generally the most effective, but one spray containing lemon eucalyptus oil is also a top performer. The vitamin B patch had no effect at all.
4. Which Natural Mosquito Repellent Works Best?, Cathy Wong, ND, Updated Oct. 5, 2016
Cathy Wong, a naturopathic doctor, sums up the evidence on several natural mosquito-repelling ingredients. She says lemon eucalyptus oil is both safe and effective, noting it actually outperforms DEET-based sprays in two studies. Bite Blocker, with geranium oil, also beats some DEET-based products in studies. Wong says most other natural insect repellants, such as citronella, don't have enough evidence to support their use.
5. New York Magazine What's the Best Mosquito Repellant?, Ashley Weatherford, Jul. 1, 2016
Ashley Weatherford, a reporter who says she's "especially prone to mosquito bites," tests eight different bug sprays in outdoor settings to see which ones keep her bite-free. She tests products with all four EPA-approved ingredients – DEET, picaridin, lemon eucalyptus oil, and IR3535 – as well as natural products with citronella and eucalyptus oils. Six products manage to keep the bugs at bay, but only three are both effective and agreeable to use.
6. Camping Insect Repellent, Contributors to, As of April 2017
Credibility: offers thousands of products to repel mosquitoes and other insects, but it's difficult to sort out the sprays and creams from items like wristbands and electronic traps that experts say are unlikely to work. Still, the effort is worthwhile as most of the top-rated mosquito repellents are listed, and many get enough feedback -- hundreds of reviews in some cases -- to be meaningful.
7. Insect Repellent & Control, Contributors to, As of April 2017
Cabela's, a store specializing in outdoor gear, offers about 70 products to repel insects—including clothing, traps, and mosquito nets as well as typical sprays and creams. The products with the most positive reviews include permethrin-based sprays and area repellents, which we don't cover in this report. However, we found one personal bug spray that gets strong reviews from about 50 users.
