Here are some ways to apply bear scents:

Spray: Spray a bear attractant on the ground, brush, trees, and stumps to create a scent trail that will attract bears. You can also spray the scent high in trees so the wind carries it through the area.

Smear: Smear a gel attractant into trees with a paintbrush.

Sprinkle: Sprinkle a hickory smoke powder across bushes to drift the scent.

Mix: Mix a concentrate with used fryer oil and splash it under the bait barrel and on trails.
Use a wax scent stick: Use a wax scent stick that can be used in all weather conditions.

Some scents that bears like include: anise, vanilla, butterscotch, fruity flavors, and chocolate.

You can also use bear scents to cover your human scent during a hunt. When placing your bait, consider the prevailing wind for the time of year and the direction you want the scent to blow.
