Fast Answers - Best Insect Repellent
Top Rated What the Research Says
•  Cutter Advanced
   (*est. $6 for 6 oz.)

>> Where to buy

Best insect repellent overall.

Experts are mixed on DEET-based insect repellents. Although effective, some dislike the distinctive smell and oily feel on the skin, and DEET can damage plastics and clothing. An alternative insect-repellent ingredient, picaridin, has been shown to be as effective as lower-strength DEET. Reviewers say the 7% picaridin concentration in Cutter Advanced protects against ticks and mosquitoes for about 2.5 hours. Unlike DEET, Cutter Advanced doesn't damage plastics, isn't sticky on the skin and is odorless, but it can cause eye irritation. Cutter Advanced is considered safe for kids as young as two months and is available in a spray or wipes. (compare prices)
•  3M Ultrathon Insect Repellent 12 Lotion
   (*est. $10 for 2 oz.)

>> Where to buy

DEET repellent for long periods or extreme conditions.

Ultrathon uses a special kind of DEET that isn't as easily absorbed into the skin, yet it is as effective as standard DEET formulas (both types can ruin plastic and paint, however). If you need long protection, its 34% concentration of DEET is the optimum amount. This insect repellent has been tested in jungle areas and is used by the U.S. armed forces. 3M Ultrathon is water-resistant, protecting against ticks and flies as well as mosquitoes for five hours or longer. Experts recommend not using any DEET repellent on babies, however. (compare prices)
•  Repel Lemon Eucalyptus
   (*est. $7.50 for 4 oz.)

>> Where to buy

Best natural mosquito repellent.

If you prefer a non-chemical insect repellent, reviews say Repel Lemon Eucalyptus is effective against mosquitoes and ticks for four to six hours. It's not equally effective for everyone, however, and it's supposed to be applied only twice per day. Unlike DEET, lemon eucalyptus oil doesn't damage plastics or synthetics, but it can stain leather. Most reviewers, but not all, like the scent and skin-feel. Mosquito repellents containing lemon eucalyptus oil are not recommended for kids under three years old, however. (compare prices)
•  Bite Blocker
   (*est. $9 for 4 oz.)

>> Where to buy

Safest insect repellent for kids.

Considered safe for all ages and for pregnant women, Bite Blocker uses only food-grade plant-based ingredients including soybean oil and geranium oil. It is effective against black flies as well as mosquitoes and ticks. As with most natural insect repellents, protection time varies greatly among individuals, but averages 1.5 to two hours, and Bite Blocker is safe to reapply as needed. (compare prices)

What the experts say, our analysis, and more...
Updated June 2008

If you've ever wondered why you seem to be a "mosquito magnet" while your spouse or friends don't seem to get bitten as often, it's not all in your head. Scientific studies confirm some people do attract mosquitoes more than others, and in the same way, research shows that every insect repellent is more effective on some people than on others. For that reason, the best-designed insect repellent reviews employ many testers and report the minimum and maximum protection time, not just the average. We found the best such mosquito repellent review conducted by Mark Fradin and John Day, published in The New England Journal of Medicine in 2002. Unfortunately, it doesn't cover the newest contenders for best mosquito repellent, which use either synthetic picaridin or lemon eucalyptus oil (a natural insect repellent) as the active ingredient.

Consumer Reports does test mosquito repellents that include these newer ingredients, but only four people test the products, and only the average protection time is reported. An otherwise well-designed review done for the U.S. Department of Agriculture, published in the Journal of Medical Entomology, tests products on only two people, but it does report the range of results. We found some insect repellent reviews in Backpacker magazine, but only one person tests each product.

The Backpacker review reports on the odor of each insect repellent, along with how it feels on the skin. These practical aspects are often ignored in the more scientific reviews, but the less formal reviews at Slate magazine and Good Housekeeping agree that they're important.

Of course, effectiveness matters most. Reviews based on lab testing conclude that wristbands, electronic mosquito repellents and insect-repellent clothing are a waste of money for most people. Although few insect repellents fail to attract praise from at least a few users, it's clear that most insect repellents that use DEET are consistently effective, while only a few alternatives work well for most people. Still, even the U.S. military is researching alternatives to DEET, because it damages plastics, paint finishes and many synthetic fabrics. It also smells bad and should be washed off the skin whenever you return indoors. Dozens of alternatives to DEET have appeared on the market, but reviews based on objective comparison tests show that only three of the alternative ingredients stand out as best.

Reviews say lemon eucalyptus oil offers the longest-lasting protection from bug bites, but it's not to be used on kids under three years old. Bite Blocker, picaridin or DEET are considered safe even for babies as young as two months (though some experts say six months is safer). The most recommended DEET insect repellent is the 34% Ultrathon controlled-release version used by the U.S. military, followed by DEET-based products with even lower concentrations.
