While you're probably correct,I've been using the oil based concoction for years and I never get ticks imbedded.No! It aint okay for your clothes. The stuff for animals is oil based so it doesn't come right off the livestock or K9. It will never dry right on you clothes. Get the stuff from repel or sawyer to treat your clothes. I'm in the woods every day and I use both the repel spray type or the pump spray from sawyer. Both work well. The more times you treat your stuff the better it works.
