How to Stop Mice from Penetrating Air Vents

Let’s talk about how to stop this now that we’ve shown that mice can enter through air vents.

Putting in vent covers

Installing metal vent covers is one of the simplest ways to stop mice from entering your air vents. Ensure the cover’s narrow openings keep mice from slipping through.

Continual Inspections

Check your ductwork and air vents occasionally for evidence of rodent activity. Look within the ducts for droppings, chewed-up objects, or nests.

Seal crevices and gaps.

Use silicone caulk to fill in any tiny cracks or gaps near the air vents. As a result, mice won’t be able to get inside quickly.

Use repellents for Mice.

Additional Considerations

Although the fundamental query, can mice come through air vents, has been addressed, there are still a few other levels to consider. Understanding them will offer you a more thorough understanding of how to handle a potential mouse problem involving the ventilation system in your home.

The Functions of Season and Temperature

The onset of a new season is one reason you can discover mice invading your home through air vents. Mice seek out warm locations to nest as the weather grows more relaxed, and your home draws them in more and more.

Ambient Temperature of Air Vents

Warm air is frequently carried by air vents, especially in the winter when the heating system is used. As a result, mice seeking warmth find them to be an even more appealing option.

Health Risks and the Urgent Need to Take Action


Several illnesses that put human health at risk, including Hantavirus and Salmonella, can be spread by mice. When you learn that mice can enter your home through air vents, you need to take immediate action to prevent property damage as well as to preserve a healthy living environment.

Asthma and allergies

Dander and feces from mice can aggravate asthma and allergy symptoms. Nobody would want these allergens circulated throughout the home via the air vents.

Pets’ Function
