Five Types of Insect Repellent to Skip

Consumer Reports has no relationship with any advertisers on this web site.

One of the upshots of final yr’s Zika outbreaks is that there at the moment are many extra insect repellents to select from.  

Last August—the peak of mosqutio and tick season for a lot of the continental U.S.—an Amazon search of repellents turned up greater than 13,000 merchandise, in accordance to researchers at New Mexico State University. This spring, that very same search turned up nearer to 25,000 merchandise—not simply sprays but in addition lotions, clothes, pores and skin patches, wearable units, and even stay crops wealthy in important oils. 

This sheer quantity of choices presents shoppers with a double-edged sword: It’s good to have decisions, nevertheless it’s not all the time straightforward to inform what works and what doesn’t.

“The recurrent outbreaks of dengue, chikungunya, and Zika have created a large market for a variety of mosquito repellent and control products,” says Immo Hansen, a scientist who research insect-borne illnesses at New Mexico State University. “But in many cases, the claims made by the vendors of these products are exaggerated or outright false.” 

Joe Conlon, an entomologist with the American Mosquito Control Association, a commerce group, stated that space repellents—merchandise that declare to create an insect-free bubble across the consumer—could be notably problematic. “They have limitations,” he says. The AMCA advises shoppers to stick to Environmental Protection Agency-registered merchandise, and says that no product is simpler than DEET. 

To assist separate the good stuff from the not-so-good, we have compiled a fast listing of merchandise which you can skip. 

Natural Repellents

It feels like such a good suggestion: Use a “natural” mosquito repellent, with an lively ingredient like clove or lemongrass or rosemary oil, and keep away from those containing chemical compounds reminiscent of DEET. 

But this is the issue: Natural repellents are regulated in a different way than different repellent merchandise. Because the EPA deems the chemical compounds they include innocent, the company doesn’t consider them for effectiveness. Because of that loophole, corporations that promote these repellents do not have to show that they really work. And our testing signifies that, in reality, they do not.

Most of the plant-based repellents CR has tested lasted only one hour or much less towards the Aedes aegypti mosquito—the type that may unfold Zika, yellow fever, dengue and chikungunya.  

Daniel Fabricant, Ph.D., president and CEO of the Natural Products Association, advised Consumer Reports that pure repellents differ of their effectiveness the identical method that different repellents do. 

The Centers for Disease Control and Prevention and the EPA each say that DEET is protected when used correctly, even for pregnant women. Our specialists agree, although they advocate sticking to merchandise that include 15 % to 30 % DEET.  

Wrist Bands

These wearable repellent units are marketed as being safer, as a result of you do not have to rub something in your pores and skin.

But Consumer Reports examined two wristband merchandise and located each of them to be ineffective: When our testers caught their arms right into a cage full of mosquitoes sporting one of two wristbands—the Coleman Naturals Insect Repellent Snap Band, or the Super Band Wristband—the bugs began biting instantly. 

Last May, the Federal Trade Comission fined another wristband maker, Viatek, $300,000 for misleading advertising of its Mosquito Shield Bands. The fee says the corporate’s claims—that the bands shield towards mosquitoes—weren’t backed up with scientific proof. 

Sonic Repellents

Ultrasonic units declare to emit excessive frequency sounds which might be too excessive for people to hear, however are simply the correct frequency to drive pests, together with mosquitoes, away. The hassle is, there isn’t any proof that they work. 

Last summer, the New York Attorney General’s Office despatched stop and desist letters to the makers of two particular manufacturers of sonic repellent—STAR Ultrasonic Pest Repeller and iGear iGuard 2.zero Ultrasonic Insect Pest Repeller. “Numerous scientific studies show that [these devices] don’t repel mosquitoes and may even attract mosquitoes,” the lawyer common stated. 

The Federal Trade Commission has additionally investigated a number of sonic repellent makers for false promoting. 

Clip-On Fans

Clip-on repellents might appear to be a terrific concept, as a result of they permit you to keep away from rubbing chemical compounds instantly onto your pores and skin. But the CDC says that wearable foggers “have not been adequately evaluated for their efficacy in preventing vector-borne diseases.” 

Our own testing of one such product—the Off! Clip-On repellent, a tool that attaches to your waistband after which makes use of a fan to flow into the chemical metofluthrin into the air round you—discovered that it provided far much less safety than our best-performing spray-on repellents. 

Perhaps most essential, Consumer Reports additionally has considerations concerning the security of the Off! Clip-On as a result of it makes use of the chemical metofluthrin, which is assessed by the EPA as a neurotoxin and as a possible carcinogen.  

Citronella Candles

Our tests of two area repellents—citronella candles and a battery-powered diffuser that blows out the chemical geraniol—confirmed they have been ineffective at protecting mosquitoes away. An oscillating pedestal fan set on excessive labored a lot better: It minimize mosquito landings by 45 to 65 %, a minimum of amongst individuals shut to it.

But your greatest guess is doing issues that discourage mosquitoes from breeding within the first place. Keep your yard free of containers full of water, resembling gutters, birdbaths, tires, wheelbarrows, wading swimming pools, and swimming pool covers. Clear away ivy and decaying leaves, as a result of mosquitoes like cool, darkish locations. And as a result of ticks like tall grass and much of shade, it is best to maintain your garden mowed and free of leaves and different particles (learn our lawn mower buying guide).
