I have a lot of spearmint on my property, Would this make a good muskrat lure. I'm thinking of chopping it up and mixing with glycerine.

I recommend 50/50 everclear olive oil for the tincture. that performed best for me on catnip and licorice

Muskrat do like spearmint. Some actually use spearmint toothpaste for an attractant.

Natural organic spearmint is fragrant but mild compared to an essential oil spearmint or a distilled type. You may want to try both ways to see what is giving you your best push for a lure. Then do some testing to see what that reveals.

coyotes like the blue altoids candy. so do SOME cats. I bet muskrats would too. One of those candys is real fragrant.

I like the wintergreen to eat occasionally myself. They are quite strong and you don't want to eat one after the other.
