we do ours at night because if you leave them out during the day bass and turtles get the bait before the cats do. we avoid fishing during the day because when bass hit the bluegill they usually get deep hooked and they die. but we have actually caught a guy trying to steal a fish off of our limblines. and we have found our jugs out in the middle of the lake with the hook wound up from someone taking our fish. some ppl just don't have any respect for others.
