TDH: Protect against ticks, mosquitoes

With more than 50 beautiful state parks and three National Parks, Tennessee offers endless ways to enjoy the outdoors – whether you’re hiking, swimming, fishing, camping, or just relaxing with family and friends.
But while you're out soaking up the sunshine, don’t forget to take steps to protect yourself from ticks and mosquitoes.
“Getting outside and staying active is a big part of summer fun here in Tennessee,” said Tennessee Health Commissioner John Dunn, DVM, PhD, EMBA. “Just make sure you're also protecting yourself from insect bites that can spread disease.”
Every year, illnesses like Rocky Mountain Spotted Fever and West Nile Virus are reported across the state. While most bites only lead to mild irritation or flu-like symptoms, in rare cases, they can cause serious illness or even death. And since there aren’t vaccines or specific treatments for many of these diseases, prevention is your best defense.
Here are some simple ways to keep yourself safe:
• Use insect repellent. Look for products with DEET, Picaridin, IR3535, oil of lemon eucalyptus (OLE), para-menthane-diol (PMD), or 2-undecanone. Always follow the directions on the label. (Note: Avoid OLE and PMD for kids under 3, and never apply any repellent near the eyes or mouth.)
• Cut down on mosquito breeding grounds. Dump out any standing water around your home – things like flower pots, gutters, watering cans, or even bottle caps can be mosquito nurseries.
• Treat your gear. Products containing permethrin can be used on clothing, shoes, camping gear, and bed nets to repel both ticks and mosquitoes. Some outdoor gear comes pre-treated. Just remember – permethrin is for use on fabrics only, not for direct application to the skin.
• Dress smart. Long-sleeved shirts and long pants offer extra protection. Tuck your pants into your socks and your shirt into your waistband. Go with light-colored clothes—they make it easier to spot any crawling bugs and are less attractive to many insects.
By taking a few precautions, you can fully enjoy everything Tennessee’s outdoors have to offer – without the itch, sting, or risk that comes with bites.
