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.
THAT product is NOT designed for clothing use. Usually a higher concentration of petroleum distillates.
Any miscalculation in mixing over .5% (point 5) may result in poisoning! (you)
