I have used Brewer's yeast and Garlic as well as front line I am not into the chemical stuff , because I live in a wooded area I am always checking the cat and dog for fleas and ticks ... whenever they are playing outside and in the garden w/us we check them ... Merilyn is getting a fenced area for himself this spring and we will make sure that we treat the area w/a natural repellant as well.
