For Great American Outdoors Day on August 4, The National Park Service is offering free admission for the day. Now families can enjoy exploring their local national parks with OFF!® insect repellent.

To help travelers plan smarter, OFF!® — the #1 most trusted insect repellent brand* — created OFF!Cast Mosquito Forecast, which predicts mosquito behavior and populations.

Mosquito Protection Tips To Enjoy The National Parks

With 37.8 million visitors to the national parks during the month of August last year, OFF!® and the National Park Foundation are teaming up to share insider tips for avoiding mosquitoes and other bugs.

• Wear protective clothing: Choose light-colored, long-sleeved shirts and pants to reduce exposed skin and discourage mosquito bites.
• Plan your activities smartly: Mosquitoes are most active at dawn and dusk, so plan your hikes and activities in mid-morning or mid-afternoon for more ideal conditions when mosquitoes are less active.
• Use a trusted repellent: Apply an EPA-registered mosquito repellent like OFF!® Deep Woods, which offers long-lasting protection for up to 8 hours (when used as directed) in wooded and high-risk areas. It also repels against mosquitoes that may carry diseases like Zika, Dengue and West Nile virus.

OFF!Cast Mosquito Forecast

This guide informs parkgoers on where to expect higher mosquito activity—so they can come prepared with the data backed from OFF!Cast Mosquito Forecast.

With the right protection from OFF!® repellents, every parkgoer can enjoy a comfortable outdoor experience at the parks, regardless of how many bugs might be present.
