Best Times To Use Bull Grunt Calls In October?

April 5, 2026

Quick Answer

The best times to use bull grunt calls in October for moose hunting are during early morning hours (dawn to 9 am) and late evening hours (4 pm to dusk), when the animals are most active and vocal.

Optimal Timing for Grunt Calls

When using bull grunt calls in October, it’s essential to target the moose during their most active periods. In the early morning hours (dawn to 9 am), the animals are often more alert and responsive to calls. This is because the morning air is typically cooler and less humid, making it easier for them to detect and respond to sounds. Aim to make 3-5 grunt calls during this time, pausing for 5-10 minutes between each call to allow the animals to process and respond.

Moon Phase and Grunt Calls

The moon phase can also play a significant role in determining the effectiveness of grunt calls in October. If the moon is in its new or waning phase, the moose are often more active and vocal, making it an ideal time to use grunt calls. When the moon is full, the moose tend to be less active, so it’s best to reserve grunt calls for the early morning or late evening hours.

Call Volume and Frequency

When using bull grunt calls, it’s crucial to vary the volume and frequency to mimic the natural behavior of a moose. Start with a series of 2-3 low-pitched grunts, followed by a pause of 5-10 minutes. Then, increase the volume and frequency to 3-5 high-pitched grunts, followed by another pause. This pattern can help to stimulate a response from the moose, and by varying the volume and frequency, you can simulate the different vocalizations that a moose might make.
