Getting Rid of Mice Stuck In Your HVAC System— And How To Keep Them Out!

We’ve all heard about the occasional mice issue, which isn’t quite out of the ordinary. They find access to certain areas in the house to keep them warm and sneak on our food storage. Their favorite places to hide are dark or small corners, like roofs, attics, air ducts, and vents.  Of course, if we can help it, we would prefer having no signs of these tiny animals pestering our living space. They grow in numbers incredibly fast, and it’s rather unhealthy to keep them hanging around. In this article, we’ll focus on the common identifying signs of mice present in HVAC systems, what are the ways to get rid of them, and how to keep them out.  

How to Identify Evidence of Mice Roaming In The HVAC System

  • Faint running sounds in the air ducts and ventilation lines
The usual first sign of mice infestation in the HVAC units, and probably in most corners of the house, are the faint sounds you can hear running around the ceiling and ventilation systems.
  • Clusters of mouse droppings (small, black, seed-like shapes)
Mice running around the house through the ventilation pipes often leave black droppings everywhere. You’ll notice their unique seed-like shapes, which are hard to miss.
  • Bitten chunks and corners in the cardboards, fabric, furniture, etc.
In their attempt to hunt for food around the house, you will notice bitten corners in food cabinets, closets, and boxes.  

How to Get Mice Infestations Out of Your HVAC Systems

It’s highly possible that mice infestations cluster in the ventilation lines of your heating and cooling systems. These areas are hard to reach for us, and they provide the most accessible routes for mice to transfer from one area to another. Follow these steps to get rid of the problem:
  • Turn off the heating and cooling system for your safety and to draw mice clusters out of the ventilation lines.
  • Open the exit points of the ventilation system.
  • Place snap traps with bait food on each exit point.
  • Get rid of the trapped mouse who takes the bait and replace it daily with a new snap trap.
  • Repeat the process until you observe that there’s no evidence left of the mice infestation around the house, specifically in the HVAC system.

How To Keep Mice Infestations From Coming Back

You can always hire a pest control unit to sweep your house from the natural mice infestations and other kinds of pests. On the other hand, here are a few suggestions on how you can prevent mice infestations from coming back to your HVAC systems.
  • Ensure that your HVAC systems are clean inside and out. Infected areas often attract as a livable condition for pests. Maintain a cleaning schedule with your trusted HVAC maintenance service providers.
  • No matter how big or small, seal all the possible entry points in your air duct, ventilation, and exhaust systems. Some leaks may require professional ductwork. Make sure that you regularly have your system checked twice or once a year. 
  • HVAC system repairs and refurbishments are extra precautionary measures you can periodically follow as well.
