Which calls are most effective for late-season bull moose?

Preparing the Call

To effectively call late-season bull moose, it’s essential to have a well-placed stand and a solid understanding of the local moose behavior. In Ontario, the best stands are typically near water sources, such as rivers, streams, or lakes, and in areas with dense vegetation. Use a call that can produce a clear, high-pitched “tongue-lashing” sound, achieved by rapidly slapping the tongue against the roof of the mouth.

Call Techniques

To elicit a response from a late-season bull, use the “grunt-grunt” call to mimic the sounds of a dominant bull challenging another. Start with a series of short, high-pitched grunts (3-5 seconds apart), then transition to longer, lower-pitched grunts (5-7 seconds apart). Repeat this sequence every 10-15 minutes to maintain interest and avoid habituation. When using the “tongue-lashing” call, focus on rapid, high-pitched slaps (10-15 seconds apart) to mimic the sound of a cow in heat.

Call Duration and Timing

In Ontario, the peak rut period for bull moose typically occurs during late September to early October, with the most intense calling activity occurring around the full moon. During this period, maintain a calling schedule of 10-15 minutes on, followed by 10-15 minutes off, to avoid habituation and conserve energy. Be prepared to call for extended periods (2-4 hours) to elicit a response from a late-season bull, as these animals can be notoriously selective and finicky.
