When should you switch from cow calls to bull grunts?

April 6, 2026

Quick Answer

Switch from cow calls to bull grunts when you start to hear bull moose responding to your cow calls and you notice a significant increase in bull activity, usually around 9-10 days into the September rut.

Identifying the Right Time to Switch

When hunting moose, it’s crucial to switch from cow calls to bull grunts at the right moment to maximize your chances of calling in a bull. Typically, you’ll start with cow calls in the early stages of the rut, usually around the first 7-8 days of September, to simulate a receptive cow. As the rut progresses, you’ll start to hear bull moose responding to your cow calls, which indicates that they’re becoming more active and aggressive.

Transitioning to Bull Grunts

To transition to bull grunts, start by making short, high-pitched cow calls to keep the bull’s attention. Then, gradually shift to louder, more aggressive bull grunts, mimicking the sound of a dominant bull. This will help to trigger a response from the bull, potentially leading to a closer encounter. It’s essential to maintain a consistent and authentic tone when making bull grunts, as this will help to build trust with the bull.

Effective Raking Techniques

In addition to switching to bull grunts, incorporating raking techniques can be an effective way to bring a bull moose in close. Raking involves making a loud, scraping sound with your antlers or a raking tool, simulating the sound of a bull making contact with a receptive cow. Start by making short, gentle rakes and gradually increase the intensity and frequency, mimicking the sound of a bull in heat. This can be an effective way to trigger a response from a bull, especially when combined with bull grunts.
