Are you looking for a cover scent or are looking to lure them in, and try to get em to nibble on your shoe strings? I have seen scent killer made in acorn scent, but I never liked it. If I use anything natural for cover scent it is cedar. I usually cut a few cedar limbs and put them in the bottom of a big rubbermade storage tote cover the limbs with an old towel or something to keep the sap off you good stuff, and let it sit for a day or so. Just hope you are not allergic to cedar.
