The treatments were garlic at 100g (A100) and 200g cow-1 (A200) for three days, Amitraz at 0.025% (Am) and negative control group. Engorged ticks were evaluated with lengh superior to 4.0 mm and flys before and at 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, and 14thday after treatment. In the 1st, 2nd, 3rd days after treatments, milk samples were taken for flavor evaluation on raw milk and soft cheese Minas-Frescal. The efficacy of treatments were 27.34; 12.31; e 97.05% for (A100), (A200) e (Am), respectively. Commercial ectoparasiticide was more efficacious in the control of ticks.
