Squirrels building nests in your ventilation is detrimental to both your home and your health. First, these nests can obstruct airflow, causing your HVAC system to work harder and potentially leading to costly repairs. The accumulation of debris and nesting materials can also introduce contaminants into your home’s air, lowering indoor air quality and triggering respiratory issues. Squirrels can chew through ductwork and insulation, reducing the efficiency of your system and increasing energy costs. Their presence also attracts insects and pests, compounding the problem. With respect to your health, the nesting materials and squirrel droppings can harbor harmful bacteria and pathogens, posing health risks when they become airborne. Consulting a professional is essential to safely remove squirrels and their nests, ensuring your home’s efficiency and your family’s well-being.
