I have had very good experience by spraying my clothing with Permanone by Repel. It's for clothing use (not skin). Spray it on your clothing, hats, socks, gear, boots, etc. a day before you pack up so it dries well. No smell, no, stain, and the ticks will just about jump off of you. I live in Southeast Virginia which is thick with ticks and chiggers and this stuff is great.

You might be able to spray it on the tent floor if it's that poly type stuff, but not on the tent fabric because it might make it leak.
