Zika is a growing threat in the United States, particularly here in the South where mosquitoes flourish in the summertime. All reported U.S. cases of Zika have so far involved people who traveled to areas with a current outbreak, but health experts have warned that local transmission cases are likely to occur in the coming weeks during summer mosquito season. Gulf Coast states, such as Florida and Texas, are seen as particularly vulnerable.1
In response to this growing threat, Consumer reports recently released their test results and ratings of mosquito repellents. "Using an insect repellent is one of the best ways you can protect yourself from Zika and other diseases transmitted by mosquitoes," said Harry Savage, Chief of Ecology and Entomology Activity at the CDC's Division of Vector-Borne Diseases. Consumer Reports' tests show that some repellents worked better than others at protecting against the Aedes mosquitoes, the type that carry Zika.
Here is a breakdown of the top recommended mosquito repellents based on overall score from Consumer Reports' tests.
|Brand & Model||Price||Overall Score**||Active Ingredients||Effectiveness Aedes Mosquitoes||Effectiveness Culex Mosquitos||Effectiveness Deer Ticks|
|Sawyer Picaridin||$8.25||96||Picaridin 20%||8 hours||8 hours||8.5 hours|
|Ben's 30% DEET Tick & Insect Wilderness Formula||$8.00||93||Deet 30%||7.5 hours||8 hours||8.5 hours|
|Repel Lemon Eucalyptus*||$7.50||87||Oil of Lemon Eucalyptus 30%

|7 hours||8 hours||7 hours|
|Natrapel 8 Hour||$9.00||81||Picaridin 20%||8 hours||8 hours||6 hours|
|Off! Deepwoods VIII||$6.50||74||Deet 25%||8 hours||8 hours||5 hours|

** Overall score is based on mosquito and tick repelling effectiveness. The displayed score is out of a total of 100 points.
Consumer Reports advise skipping most products made with natural plant oils, such as California Baby Natural Bug Blend (a blend of citronella, lemongrass oil, cedar oil, and other ingredients) and EcoSmart Organic, (which includes geraniol, rosemary oil, cinnamon oil, and lemongrass oil). They did not last for more than 1 hour against Aedes mosquitoes, and some failed almost immediately.1
