There are multiple ticks that transfer multiple diseases. Permethrin, in my opinion, is essential. Spray your clothes well, and it will be very effective. It also helps to tuck your pants legs into your boots. I have had friends that have contracted Lyme and other tick borne issues. I have picked up Alpha Gal allergy, which is also caused by ticks, so I know personally what a problem ticks can cause. Alpha Gal makes you allergic to mammal meat. Imagine no beef, no pork, no lamb, no venison, no elk, etc. I had reactions for over 20 years, and have pretty much figured out that I have had this issue all that time, even though I only diagnosed it about a year ago. Don't be fooled thinking Lyme is the only issue related to ticks, as there are lots of health issues involved. If you walk into the woods and fields, you need to address the tick issue.
