You can use barriers or repellents to discourage the beavers.  Once all initial construction activities have been completed, beavers spend their time eating, maintaining the various structures, and collecting food for the winter. Beavers are herbivores, which means they eat plants and plant material. A beaver may consume up to 20-30 oz. of food per day (about equal to the bark and smaller branches of a 2-inch diameter tree every 2 days). They consume a wide variety of aquatic plants and trees, including pine, red cedar, willow, alder, tulip poplar, red maple, dogwood, sweet gum, beech, and others that grow near water. During spring and summer, beavers consume mostly grasses, sedges, rushes, some farm crops (e.g., soybeans, corn), and the succulent new growth of small bushes. As winter approaches, they switch more to woody material (i.e., trees and branches). Beavers cut felled trees to manageable lengths for transport back to the lodge area and then anchor the stems and branches into the sand or mud at the bottom of the pond. In climates where water bodies are subject to freezing over, beavers will use this underwater food cache of stored tree sections to survive the winter under the ice. Once all the bark and leaves have been stripped and eaten, these limbs and branches will be used as building materials to maintain or repair the dam and lodge. Given Virginia's mild winters, beaver ponds here rarely freeze over for extended periods of time, so beavers will cut and eat fresh trees and plants throughout the winter months. In the event of an unusually harsh winter, beavers will use the stored food cache and rely on their fat reserves to make it through the winter.
