For trapping sets and predator calling, I use a great homegrown fear remover that works equally well in snow as in dirt. I use the droppings, urine and hair from domestic rabbits as a fear remover, a curiosity scent, and a distracter.
You can easily collect the items. The most difficult part is finding someone who raises rabbits. Ask around at feed stores, and you’ll find a source. Better yet, raise some yourself and have some tasty meals as well. One rabbit yields more material than you need.
To collect droppings and urine, use trays or pans beneath the cages. On a daily basis, empty the pans of urine into small screw-top bottles, leaving room for freeze expansion. You can place the pellets in plastic baggies, which is the amount you’ll need for a set, then freeze them. To obtain loose hair, check the fluffy nests made by the female for her nest. You can also cut strips of hair from the dried skin of butchered rabbits — domestic or wild. Bag loose hair and hair strips. Set urine and pellets out to thaw the night before a hunt. Don’t microwave or heat to thaw.
For predator callers, the rabbit parts serve a unique purpose. You need to attract, distract and occupy the attention of the animal that believes it is moving in for an easy meal. A strip of rabbit hair suspended and moving with the wind helps fulfill all these needs.
On the anticipated line of approach, choose a site or two for scatterings of pellets, urine and loose hair to give your prey something to hone in on. Scatter some around your remote caller and/or decoy to add absolute realism to your set.
