I know this base recipe works for us, and I usually try some new addition every batch or two. 

I got this  idea from Dr Pitcairn's Lemon Dip for fleas but I needed something that worked well on ticks too. 
this has been very successful for us. You may need to use it more or less, or use more lemon, etc. to find the exact mixture that works for you.
I currently have 3 40-45 pound dogs that like to spend alot of time outside. One batch lasts us about a month.
