Top Tested Repellents for Mosquitoes and Ticks

Consumer Reports tested insect repellents to fight mosquito and tick bites

Mosquito and tick-borne diseases are on the rise nationwide. The best way to protect yourself is with a good insect repellent.

Many of the highest-rated products contain DEET at concentrations of 15 percent to 30 percent. Research has shown that DEET is safe when used as directed, even for kids and pregnant women.

As part of Consumer Reports expert testing against mosquitos, a standard dose of repellent is applied to each test subject’s forearms. Each subject tests two repellents, one on each arm, at a time, then sticks each arm into a cage of 200 disease free mosquitoes of one species for five minutes.

The repellent fails if there are two bites in one exposure period, or one bite in each of two consecutive sessions. Consumer Reports did not test all repellents against ticks, but previous test results and further research indicate that any product that protects from mosquito bites will also likely protect from tick bites.

Consumer Reports' two top-rated repellents contain DEET. Total Home CVS Woodland Scent Insect Repellent and Off! Deep Woods Insect Repellent VIII Dry.

Also performing well in Consumer Reports' testing were the 30 percent oil of lemon eucalyptus repellent and the 20 percent picaridin repellent.

Research suggests both are safe, though Oil of Lemon shouldn’t be used on children under three years old.

And to get the best protection from any of these repellents, you must apply them properly. So follow the directions on the label.

Now, you may worry about using a chemical such as DEET on your children and want to go the natural route, perhaps with a repellent containing citronella or other essential oils. The Environmental Protection Agency — and Consumer Reports — says that DEET with concentrations of 30 percent or less is safe for children when used as directed.

And Consumer Reports' tests have shown that most natural products, with the exception of oil of lemon eucalyptus, don't perform well against mosquitoes.
