If it is the mice that you want to attract them there them why not just trap a mouse and us it. I can trap a lot more mice in a mouse trap and do it for much cheaper.
If I was going to use this set i would not use the star or trapezoid pattern...it would only work if you use 10 traps and make a circle around the bag......no gaps that is the secret to the whole thing....
Stanley Hawbaker outlined putting mice in a tin travel cage in the back of cubby sets. The copy of his book I have is from the 1940's. (So the whole mice scent at your set idea has been around for a while!)
If you want to attract things with mice, use live mice or an electronic squeaker! You can also raise some of those .99 cent mice at the pet store and put their dirty cedar bedding in your dirt holes, or use them to scent your weasel boxes.
