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

You don’t want to think about it, but often times dust isn’t the only thing that is in your duct system. You might have heard animal noises coming from air ducts and fear you have unwanted visitors. You can try and lure the little guys out but they may be nesting and refuse to leave their babies. Call Service Experts Heating & Air Conditioning for a thorough duct cleaning and we will assure your duct system is free of all these uninvited house guests, including:

Bugs and Insects

Nothing is worse than working to kill a spider and seeing it escape into the air vent. It’s impossible to get it now and all you can do is lie in bed and imagine the spider laying all those spider eggs. You may even think you hear a couple scurrying around your duct system. Don’t worry. Service Experts Heating & Air Conditioning will come to your home and give you a full duct cleaning and ensure that spider and any of her bug friends are good and gone. Eggs, too.


When rodents make their way into your duct system, commonly through gaps in the duct work and fractures in the foundation or home exterior, it causes several issues. First, wildlife can leave droppings behind and can tear up anything they get into, including Christmas decorations or old baby clothes you’re keeping in your attic. Second, animals tend to chew, which can result in exposed wiring. That combined with the dried grass and leaves they’re likely bringing in to manufacture a nest, and now there’s quite the fire danger in your attic, duct system, and behind your walls. A professional duct cleaning can remove rodent droppings or nests, but you could also need to call an expert wildlife removal company to remove the rodents and possibly an electrician if there has been any damage to wiring.


Birds usually get into safe and warm places to nest, like your air vents. Nests mean babies, which means they are bringing food to babies, and that means BUGS. If you have birds in your vents, you’ll likely end up with bugs in your home. But that’s not the end of it. Birds construct nests in your vents, and given the vast amount of leaves and grass they use to assemble said nest, it can wind up fully clogging a vent, preventing any airflow. As with rodents, a professional duct cleaning from Service Experts Heating & Air Conditioning can remove any droppings, feathers, or other potential illness-carrying leave-behinds. You may also need animal control to actually remove the birds from air vents or attics.

Mice in Air Ducts

If you’ve got mice in your home’s ductwork, you should take steps quickly to remove them. Mice chew through electrical wires and leave droppings like all rodents, but they also multiply quickly. And when they run around in the ducts, treating it like the highway of your residence, they may die in the ducts. This creates an unsanitary situation, and you may notice it due to the smell.

You may guess mice because of the noises you hear – plenty of scratching and scrabbling in ducts. Or you could actually spot one making an escape into the heating vents in your house. You could even confirm their passage by inspecting the ducts for mice feces. Either way, if you suspect mice you have some choices. You could trap them yourself, by setting traps on the interior of each vent and checking them in the morning. Or you might decide to contract a professional exterminator.

After you have verified that the mice are removed, you should have your air ducts expertly cleaned by an HVAC company. If mice have been there, they will have left feces in your ducts. Mice droppings are toxic, and if you don’t remove them from your ducts they can make you and your family sick. Service Experts Heating & Air Conditioning offers duct cleaning services that will remove most debris from your home’s ventilation system.
