When I think of attractant I alway remember buying some salmon egg spray years ago. My brother in law and I were using plastic grubs for bream, crappie and bass. For some reason I was catching fish without the spray but my BIL was not. So we sprayed his grub and he caught a night bluegill on the next cast. Every 8 to 10 cast he would have to spray his grub, as CoachBob said he was probably covering up something on his lure. Later we saw the parents of a good friend out in their boat and my BIL told Mrs. C to let him spray her grub. The next cast she caught a turtle. I don't think she has ever forgiven or let him forget that. She was sure it was a turtle attractant.
