For anyone not wanting to use chemicals chrysanthemum oil is really good as a deterrent but permetherin on clothing is really good, we use tick clothing in the uk which is great, i also use a spray for skin contact i will post a pic tomorrow and have not had a single tick since taking these precautions. on the west coast of Scotland where i hunt is the most concentrated area for ticks and the red deer are crawling with them it is unreal how many are on a single animal and each year gets worse, take care guys its a terrible thing to be hit with any disease the ticks carry it never leaves you, if you get a ring or red rash get to the doctors and get a large dose of antibiotics as testing is a waste of time and you don't have time to waste, regards, wayne
