What can I do to stay healthy? 

Before you go outside 

  • Know where ticks live! 
    • Ticks live in grassy, bushy, or wooded areas. They also live on animals.  
      • When hiking or walking outside, try to stay on trails.  
      • While hunting or trapping, use gloves when touching an animal or harvesting* an animal. 
  • Hunting, camping, hiking, gardening, or playing outside can bring you close to ticks.  
  • Treat your clothes, gear (boots, tents, backpacks or camping gear), or any outdoor equipment with insect repellent*.  
  • Wear long pants, long sleeves, and long socks when outside.   
  • Use insect repellents* while hiking, camping, hunting, or being outside. Ask an adult to help you with insect repellent*.  

Before you come inside after being outside 

  • Check your clothes, pets, and gear (backpacks, shoes, tents) for ticks before going inside.  
  • If you have a tick on you, ask for help to have it removed.   
  • Shower soon after being outside to wash off ticks and do a tick check.
