6 On Your Side: CR’s Top Tested Insect Repellents

(ABC 6 News) – Summer is almost here, which means vacations, backyard barbecues, beach days, and unfortunately bugs.

Insect repellent is a great way to battle against buzzing mosquitoes in your face, itchy bites, and creepy ticks.

But not all bug sprays are effective, which is why Consumer Reports put 53 repellents to the test to find out the best ones for you.

How does sticking your arm in a cage filled with hundreds of hungry mosquitos sound? That’s exactly what Consumer Reports has brave volunteers do.

A standard dose of repellent is applied to test subjects’ arms.

After 30 minutes, they stick their arms into cages of 200 disease-free mosquitoes for 5 minutes and testers count every time a mosquito lands on their arm or bites.

The process is then repeated until the repellent fails or until 8 hours has passed.

“A repellent fails our test if a mosquito bites twice in one 5-minute session. Or if there’s one bite in each of two consecutive 5-minute sessions,” explains Consumer Reports’ Catherine Roberts.

Now, while those mosquitoes in these tests are disease free, the ones you’ll encounter might not be.

“Mosquitoes and ticks can spread serious bug-borne diseases like Lyme disease and West Nile virus, and using an effective insect repellent is one really good way of reducing your risk of contracting those diseases,” says Roberts.

Key word there is “effective.”

CR’s tests found that many of the most effective repellents in fighting against mosquitoes and ticks contained 25% to 30% percent Deet as its active ingredient.

Properly applying the repellent is just as important as the kind you use. Follow the directions on the label, and use a thin coat on all exposed skin. You can also spray on top of your clothes, but don’t apply under your clothing.

If you’re wary of Deet, CR’s tests found some repellents that contain 20% picaridin or 30% oil of lemon eucalyptus were effective as well.
