Quick Answer
Deer stop using mineral licks after a while due to the depletion of minerals and the deer's adaptation to the available nutrients. This can also be caused by the presence of other food sources that provide similar essential minerals. Furthermore, if the mineral lick is not adequately replenished, deer may lose interest.
Natural Mineral Sources and Deer Behavior
Deer rely on natural mineral sources such as limestone, dolostone, and shale, which provide essential minerals like calcium, phosphorus, and potassium. These natural sources also contain other beneficial minerals like magnesium, zinc, and copper. When a deer has access to these natural sources, it may not require the minerals provided by a supplement or mineral lick.
Mineral Lick Depletion and Replenishment
A general rule of thumb is to replenish mineral licks every 2-3 weeks, depending on the number of deer using the lick and the size of the lick. For example, a large mineral lick serving 20-30 deer may need to be replenished every 2 weeks, while a smaller lick serving 5-10 deer may only need to be replenished every 3-4 weeks. This ensures that the deer continue to have access to an adequate supply of essential minerals.
Legal Considerations and Mineral Lick Placement
When placing a mineral lick or supplement, it’s essential to consider local regulations and ensure that the location complies with hunting laws. Typically, mineral licks should be placed at least 100-200 yards away from any public road or trail to avoid disturbance and maintain a safe distance from human activity. Additionally, mineral licks should be placed in areas where deer are most likely to frequent, such as near bedding areas or food sources, to maximize their effectiveness.
