New York wildlife rehabilitator Karenlynn explains what squirrels actually eat and what they really do with, including storing nuts, seeds, leaves, and other food for winter storage. Despite the misconception that squirrels primarily eat nuts, this misconception can be more harmful than people realize. While squirrels often scavenge for nuts, they actually store them for future use and use them for better nutrition. They also store nuts for later food, which they use in a process called caching, which allows them to create a winter supply. Despite this, squirrels are known for their opportunistic nature and tendency to dig holes and destroy gardens in search of nutritious snacks. They are also noted for their efficient gardeners, helping thousands of new plants sprout every year.
