Treat clothing and gear with permethrin products, which remain protective after several washings. Use Environmental Protection Agency (EPA)- registered insect repellents external icon containing DEET, picaridin, IR3535, oil of lemon eucalyptus (OLE), para-menthane-diol (PMD). Do not use insect repellent on babies younger than two months old or under 3 years. If you work outdoors, find more information about protection at the NIOSH Tick-borne Diseases Workplace Safety and Health Topics. Check your body for ticks after coming indoors. Shower soon after being outdoors. https://www.cdc.gov/ncezid/dvbd/media/stopticks.html Thanks..
