I use the sawyer and it has changed my life.
Before, I spent the entire summer covered in chigger bites just from going out to my backyard garden/orchard.
Now, I am bite-free.
I started using the Sawyer product last year after a couple of ticks found their way to me.
Not a single tick since then
I just spray my jeans from the knees to the ground and let dry. I do it at the start of the gardening season and again a month later. I did not spray my socks or my shirts
