Search Permethrin on Amazon and mix it yourself in a spray bottle. I'd say buy the Permethrin SFR concentrate but I don't think Cali will let you have it in that concentration. Been mixing it and treating my hunting clothes for years and haven't found a tick yet. Works pretty good on flying critters too. Check the dogs topical flea and tick products, many use permethrin so when mixed properly it's safe for dogs.
