Oh yes they can! Squirrels can cause a variety of damage when they infest an attic. Some of the most common types of damage include:
Chewed wires: Squirrels have a natural instinct to chew on objects to sharpen and control the growth of their teeth. In an attic, they may chew on electrical wires, which can lead to service interruptions, fires, or electrocution.
Damage to insulation: Squirrels may tear up or compress attic insulation to create nests, which can reduce the effectiveness of the insulation and increase energy costs.
Structural damage: Squirrels have constantly growing teeth and may chew on wood framing, support beams, or joists in the attic. Over time, this can weaken the structure of the home.
Water damage: Squirrels may chew through roofing materials, such as shingles or soffits, which can lead to water leaks and damage to the interior of the home.
Fire hazard: Squirrels may carry branches, leaves, and other flammable materials into the attic for nesting, which can increase the risk of a fire if they come into contact with exposed wires.
Health risks: Squirrel urine and feces in the attic can create a foul odor, stain the ceiling, and potentially spread parasites or diseases that can be harmful to humans and pets.
Damage to personal belongings: If you use your attic for storage, squirrels may chew on or damage your belongings, such as furniture, boxes, or clothing.
To prevent squirrel damage in your attic, it is important to seal any gaps or openings that may allow them to enter the home and to keep trees trimmed away from the roof to prevent easy access. If you see, hear or suspect a squirrel infestation, it is best to contact a professional to safely and humanely remove the squirrels and repair any damage they may have caused.
