Might try something with Picaridin if the DEET and permethrin aren’t getting the job done.
Or move to Montana. Don’t move to NC. We’re full up with both people and ticks.
I'm a big fan of Sawyer Picaridin Lotion and spray. When we first started cleaning up the farm, I had a tick fall on my arm from walking through high grass. Looked down and seen it crawling on my arm, which was treated. It crawled to the side of my arm and jumped off, it did not like the Picaridin. Been using the stuff for 8 years and so far, no ticks.
Since my wife suffers from Lyme disease, I make sure that I take precautions because I don't want to go through what she has gone through.
Just a little footnote, you don't always get the red bullseye mark with tick bites and lyme. The studies are showing between 30-40% of the people do not get the rash, which my wife did not, so they didn't treat her. Ten years later, they finally tested her to find out that she had the markers for long term Lyme.
