Yes I know, I buy stuff to spray that kills ticks becuase I’m constantly pulling them of the dog and often I find them on my clothes or my skin. I’ve learned to check, it can be nasty - which is why I spray.
Found some good stuff online that works and isn’t harmful, but nothing beats DDT for killing those rascals.
But it also kills off bees and other useful insects. Precise application is critical.
The other thing you can do is try to keep the low brush cut down. The ticks tend to hang out in the brush and weeds that are 6” to 2’ tall. That is where they tend to jump on you. I go around with my Stihl brush trimmer and keep the stuff around the yard(grass that I mow) knocked down.
My mother in law actually tucks her pant legs into her socks so the ticks can not jump on your ankles and crawl up your leg.
Also, I have a few bags left of diazinol crystals still in the shed. I mostly use that to keep carpenter ants from coming in the house. I sprinkle it right around the foundation. I bought six bags about ten years back when I heard they were going to make it illegal.
What sprays are using?
