Pests such as squirrels, mice, and chipmunks can cause a great deal of property damage to your home. Squirrels and other critters commonly gain access to roofs and attics via power lines and utility poles. They can quickly chew through the exterior of the roof to gain access to the warm attic. Once inside, these animals build nests, chew through wood and wires, and quickly locate the food sources inside the home. Fortunately, Critter Guard is an effective method of preventing critters from entering the attic via power lines and causing damage to your home exterior.
