ThermaCells work pretty decent, I always use those when hunting.
They have sprayers that connect to the hose you can spray. I probably wouldn’t do thus though, just another option.
Wear clothing that covers you all over, they make like mesh jumpsuits you can put over your clothes that aren’t bad priced. Similar to how they do in Africa at night on the beds. Give it a Google you will see many styles
I feel your pain, bloodsuckers are painful after alot of them.
