Battling Zika Virus: Comparing Anti-Mosquito Products

The spread of the Zika virus has consumers looking for protection.

The FTC said the company sold the band without reliable scientific evidence to back its claims. The company said it never claimed to protect against all mosquitoes, also denying that it took "advantage of consumer concerns for the Zika virus."

"To date, Viatek stands behind the empirical scientific evidence that resulted from multiple tests performed as to the efficacy of their mosquito bands. The tests were conducted by a leading American university and a distinguished professor of entomology, who provided competent and reliable evidence for the claims," the company said in a statement.

Meanwhile, in a report released this morning, Consumer Reports said it tested several brands of mosquito-repellent clothing and found that while the shirts did help to protect against mosquitoes, none offered full protection.

The report said none of the shirts tested was as effective as an ordinary shirt that was sprayed with DEET, adding that the shirts’ manufacturers stressed the importance of wearing the clothing as well as a repellent.

The shirts tested were L.L. Bean’s permethrin-treated Crew shirt ($80), Bugsaway Breez’r by ExOfficio ($85) and Talisman by ExOfficio ($85). According to the report, the shirts were treated with 0.52 percent permethrin, the industry standard. It also said manufacturers claim the permethrin would last for 70 washes.

Consumer Reports said it tested new shirts and shirts that had been washed 25 times. As controls, it also tested untreated shirts made of similarly thick materials, as well as one untreated shirt that was sprayed with Ben’s 30 percent DEET Tick and Wilderness formula, Consumer Reports’ top-rated DEET product.

The DEET-sprayed shirts prevented all mosquitoes from landing, and therefore prevented all bites, the report said.

Insect Shield, the technology used on ExOfficio BugsAway clothing, said in a statement to ABC News that its technology provided “an inexpensive and automatic way to protect from Zika virus.”

In a statement to ABC News, L.L. Bean said: “While contact repellents like permethrin, which is in our No Fly Zone apparel and spatial repellents like Deet represent vastly different technologies, our No Fly Zone garments give folks yet another effective choice for battling biting insects and insect-borne diseases."

Hadyn Parry, the CEO of Oxitec, spoke at a congressional hearing Wednesday about his company's mosquitoes, which are genetically modified in an effort to reduce the population of the Aedes aegypti mosquito, the species primarily responsible for the spread of the Zika virus.

The FDA has given an initial "Finding of No Significant Impact" regarding the proposed test in the Florida Keys.
