Various pests can find their way into your ductwork, creating a range of problems. The most common include rodents, insects, and even birds. Knowing which pests to look out for can help you take preventative measures.

Why Do Pests Invade Ductwork?

Pests seek out ductwork for warmth, shelter, and a hidden route to move around your home. The dark, enclosed spaces provide an ideal environment for nesting and hiding from predators.

Birds may nest near your HVAC system, and their droppings can contaminate the ducts. This can lead to blockages and unhealthy air quality.


Squirrels can chew through ductwork insulation and create nests, causing significant damage and potential fire hazards.


Bats can enter through small openings and leave droppings that contaminate the air, posing serious health risks.
