Why Do Squirrels Eat Wood

Why Do Squirrels Eat Wood?

Squirrels are known for their acrobatic skills, bushy tails, and love for nuts. However, you may be surprised to learn that squirrels also have a penchant for eating wood. While it may seem puzzling at first, there are several reasons why these furry critters indulge in this unusual behavior.

1. Nutrient Source: Squirrels have a varied diet, and wood is a source of nutrients such as manganese, calcium, and sodium. These minerals are essential for their overall health and development.

2. Dental Health: Squirrels’ teeth continuously grow throughout their lives. Gnawing on wood helps them wear down their teeth, preventing overgrowth and maintaining proper dental health.

3. Food Storage: Squirrels are known for their habit of hoarding food for the winter. By chewing on wood, they create holes to hide their stash of nuts, acorns, and other food items.

4. Boredom and Stress Relief: Squirrels are highly active creatures, and chewing on wood provides them with mental stimulation and stress relief. It helps keep them occupied and prevents boredom.

5. Nest Building: Squirrels build nests, called dreys, using twigs and leaves. Gnawing on wood helps them break down branches and create suitable materials for constructing their cozy homes.

6. Bark Consumption: Squirrels often strip the bark off trees and eat it. The soft inner layer of the bark, known as the cambium layer, provides squirrels with a nutritious and easily digestible food source.

7. Natural Instinct: Wood-eating behavior is believed to be a natural instinct that has been passed down through generations of squirrels. It is a part of their innate foraging and survival skills.
