I go to Ollies, Home Depot, or Wal-Mart and get the Tick and Flea killer that is used to threat carpets and dogs. The brand that I have out in my vehicle now that works great is RAID Flea Killer... It works on Fleas and Ticks... It's for home use and for spraying on pets... Actually kills Ticks on contact.. Since it used for pets too it would probably be a bit safer for you instead of shooting quantities of Permethrin into the bag.. I do use Permethrin on my boots and clothes to kill ticks in the outdoors.. You can get a large bottle of Permethrin at Dick's sporting goods in the camping department.. Use this in the warmer months when calling to keep ticks off you...
