Hey Shane70! How's it going? What I do to make my own shrimp scent is to take 4oz. of worm oil and add powdered shrimp from the grocery store spice isle, add 1bag (about 2oz.) to worm oil, and cook it on low heat on the stove until it starts to boil, then turn off and let it set until slightly warm, then I strain liquid through a coffee filter 1 to 2 times to remove all of the shrimp powder ( if any of the powder gets into hot plastic it will bubble Big time!) It has worked very well for me cooked into plastic and when bagging baits. I hope this helps you out.
