Hi Paul. There are many options to get rid of ticks. You can use any anti-tick powder and shampoo like Erina EP. Or you can use a spot on (to be selected based on body weight). If you have tried all of these, and ain't working at all, go for a tablet like Simparica or Bravecto. If you want to try a herbal product, 'scooby dub-dub' is another option.
