Yes, that permethrin is amazing stuff Anthony. I do the same during hunting season. Have watched ticks start crawling across treated clothing . They would start making circles and just flat die. My cousin used to spray a rag and wipe down his horse. It would kill the biggest meanest black horse flies. He read the percentage on that bottle then bought full strength and started mixing his own for the horse and his clothes. Said it was cheaper. It in fact was stronger than what is sold and recommended to use like you, and I do. Cousin Mike found out he had bladder cancer that had went all over his body. I can't say it was this product, but he did tinker with the mixture. He was a long-time chain smoker like in 55 years also. Who knows but I believe in this product used as recommended.
