What scents attract bears most effectively during fall?

Food-Related Scents

In the fall, black bears are primarily attracted to food-related scents that signal the availability of high-calorie sources. These scents include, but are not limited to, salmon, berries, and honey. In areas where salmon runs are present, the smell of raw fish can be particularly effective in attracting bears. For example, in a study conducted in Alaska, it was found that a scent lure consisting of 1 part fish oil to 3 parts water was effective in attracting bears from up to 1 mile away.

Plant-Based Scents

In addition to food-related scents, certain plant-based scents can also be effective in attracting bears. For example, the scent of ripe berries, particularly blueberries and raspberries, can be particularly attractive to bears in the fall. In a study conducted in the northeastern United States, it was found that a scent lure consisting of 1 part crushed blueberries to 2 parts water was effective in attracting bears from up to 500 yards away. Other plant-based scents, such as the oil extracted from the leaves of the mountain ash tree, have also been found to be effective in attracting bears.

Scent Strength and Duration

When using scent lures to attract bears, it is essential to consider both the strength and duration of the scent. Bears have a highly developed sense of smell, but they can also become desensitized to strong scents over time. To maximize the effectiveness of a scent lure, it is essential to use a scent that is strong enough to be detected by bears from a distance, but not so strong that it becomes overwhelming. A general rule of thumb is to use a scent that is 1-2% concentration, and to refresh the scent every 1-2 hours to maintain its effectiveness.
