At the Twilight's Last Gleam - Be Sure Repellent is on Your TEAM!

Jul 1, 2010

Independence Day is upon us once again! Many of us will be celebrating America's "Birthday" in the evenings, outdoors, with fireworks, barbecues and family gatherings.

And you won't be alone! West Nile virus carrying mosquitoes could be celebrating with you! Reduce your chances of being bitten and infected with West Nile virus by following these few simple repellent guidelines:

Apply a repellent containing DEET, picaridin, oil of lemon eucalyptus or IR3535 before going outside. Always follow the label directions carefully and reapply as necessary.

Use just enough repellent to cover exposed skin. Heavy application doesn't mean longer protection.

When using spray repellents do not spray directly on face--spray on hands first and then apply to face.

Do not allow children to handle the product. When using on children, apply to your own hands first and then put it on the child.
