I have not bought any flea or Tick med this yr better knock on wood. I have used the Downy to rinse them after bathing them and put downy sheets as well in there beds. So far I have not bought any this yr. I also spread seven pellets in the fenced in yard where they go out to play everytime I mow I sprinkle the pellets. I have not seen no ticks at all and maybe two fleas .
