Here's a thought.. About a month ago, while brush cutting, i saw about 20 ticks on my right leg, no joke.
I had a overspill of diesel from the tank side of my tractor... Upon seeing the the ticks, i whiped my hand over the diesel "spil" and rubbed over my leg, some of tht ticks had dug in. Upon the diesel being applied, they all fell off. And I mean ALL I watched them fall in amazment upon a straightaway of cutting.
So, it's not great to go greasing yourself in diesel, it beats getting a disease from a tick.. But to me the take away is, check yourself completely after being in a tick area and treat appropriatly. In my case with #2 fuel LOL
