What's Crawling Around in Your Home's Air Ducts?

You don’t want to think about it, but often times dust isn’t all that is in your duct system. You might hear animal noises coming from air ducts and realize you have unwelcome visitors. You can attempt to lure the little guys out but they may not leave their babies if they are nesting. Call Roy Inch & Sons Home Services by Enercare for a thorough duct cleaning and we will ensure your duct system is free of all these uninvited house guests, including:

Bugs and Insects

Not much is worse than aiming to kill a spider and seeing it run into the air vent. It’s impossible to get it now and all you can do is sit on the couch and imagine the thing laying all those baby spiders. You may even believe you hear some scurrying around your duct system. Don’t worry. Roy Inch & Sons Home Services by Enercare will come out and give you a full duct cleaning and make sure that spider and any of her creepy-crawly friends are out of there. Babies, too.


When rodents make their way into your duct system, generally through gaps in the duct work and breaks in the foundation or home exterior, it causes multiple issues. First, rodents can leave droppings behind and can ruin anything they encounter, including Christmas decorations or baby toys you’re storing in your attic. Second, rodents tend to chew, which can leave you with exposed wiring. That joined with the twigs and dried grass they’re likely taking in to manufacture a nest, and now there’s quite the fire risk in your attic, behind your walls, and in your duct system. A full duct cleaning can get rid of rodent droppings or nests, but you might also need to call animal control to remove the mice, squirrels, or other wildlife and possibly an electrician if there was any wire damage.


Birds typically find safe and dry places to nestand your air vents meet that criteria. Nests mean babies, which means they are feeding babies, and that means BUGS. If you find birds in your vents, you’ll probably end up with creepy-crawlies in your home. But that’s not all. Birds assemble nests in your vents, and given the large amount of leaves and grass they use to build said nest, it can wind up fully clogging a vent, stopping any airflow. As with rodents, a professional duct cleaning from Roy Inch & Sons Home Services by Enercare can get rid of any droppings, feathers, or other potential illness-carrying leave-behinds. You might also need animal control to actually remove the birds from your vents or attics.

Mice in Air Ducts

If there are mice in the air ducts, you should take steps to quickly remove them. Mice gnaw electrical wires and leave droppings like all rodents, but they also grow their population quickly. And when they run around in the ducts, treating it like the beltway of your home, they usually die in there. This creates an unsanitary situation, and you may notice unpleasant scents.

You might think of mice because of the noise you hear – lots of scratching and scrabbling inside sheet metal. Or you might actually notice one making an escape through the air vents in your walls. You may even confirm their passage by inspecting the ducts for mice feces. If you suspect mice you have a couple choices. You could trap them yourself, by placing traps on the interior of each duct and checking them in the morning. Or you might decide to pay for a professional exterminator.

Once you’ve determined that the mice are gone, you should have your air ducts thoroughly cleaned by an HVAC company. If mice have been present, they will have left mice refuse in your ducts. Mice droppings are toxic, and if you ignore them in your ducts they can make your household sick.
