I use Sawyer Permethrin Tick Repellant and DEET plus. It is available at Dicks Sporting Goods and it is the best I have found. You spray it on your clothes and it lasts for up to 6 weeks. Even through washings. I retreat every 4 weeks and I have not been bitten by a tick in 2 years. Which is when I started using this product.
