Something natural that works for me I buy 4oz of clove oil. I put 1oz in a spray bottle and add 8 oz water put it on there body and fleas are dead. Nags and Mosquitos stay away too. Repeat 2 times a week. I even put it on me here in Florida too much Mosquitos. I love the smell too. I discovered this from my breeder as to my princess is allergic to frontline.
