Are they the same as the wax worms we use for bait? If so I remember using them and mousies as a kid ice fishing in Minnesota. That was back in the sixties and seventies, and two years ago when my kids got hooked on ice fishing also.
Are they also the same moth/miller larvae that destroyed a lot of coats and we used moth balls on?
Fortunately I haven't had to get close and personal with them, other than when I dump them out of my moth trap.
