Sprayon Insect Repellent II S00856 contains a 23.75% concentration of DEET, which provides up to four hours of protection under normal use.

To protect against and combat this summer's return of the West Nile virus (WNV), Diversified Brands provides an insect repellent with the industry's highest concentration of DEET. Sprayon Insect Repellent II S00856 is EPA-registered and can be safely applied to skin, clothing and anywhere insects are a problem. With a 23.8% concentration of N,N-diethyl-3-methylbenzamide (DEET) that lasts for up to four hours, Sprayon Insect Repellent II provides longer-lasting protection against mosquitoes than repellants with lower time-released concentrations.

West Nile virus (WNV) was first detected in the fall of 1999 in the New York City area. As a result, 62 persons infected with the virus were hospitalized and seven died. It was then discovered that a person becomes infected with the virus from the bite of a virus-carrying mosquito. WNV has since traveled westward in the United States, infecting numerous people in states including Colorado and South Dakota.
