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

You don’t want to think about it, but sometimes dust isn’t all that is in your duct system. You might hear animal noises coming from air ducts and notice you have unwelcome visitors. You can attempt to lure the creatures out but they may not leave their babies if they are nesting. Call Service Experts Heating & Air Conditioning for a thorough duct cleaning and we will assure your duct system is free of all these nasty house guests, including:

Insects and Bugs

Not much is worse than working to kill a spider and watching it run into an air vent. You can’t get to it now and all you can do is sit on the couch and imagine it laying all those spider babies. You may even think you hear some racing around your duct system. No worries. Service Experts Heating & Air Conditioning will come out and give you a complete duct cleaning and assure that spider and any of her creepy-crawly friends are evicted. Babies, too.


When raccoons, mice, and other furry visitors find themselves in your duct system, generally through gaps in the duct work and fractures in the foundation or home exterior, it causes many issues. First, wildlife can leave droppings behind and can destroy anything they get into, including Christmas decorations or old baby clothes you’re keeping in your attic. Second, rodents tend to chew, which can cause exposed wiring. That joined with the dried leaves and twigs they’re likely bringing in to manufacture a nest, and that creates quite the fire hazard in your attic, duct system, and behind your walls. A full duct cleaning can get rid of rodent droppings or nests, but you may also need to call animal control to remove the furry visitors and perhaps an electrician if there has been any damage to wiring.


Birds typically get into safe and dry places to nestand your air vents meet that criteria. Nests mean babies, which means they are finding food for babies, and that means BUGS. If you have birds in your vents, you’ll presumably end up with creepy-crawlies in your home. But that’s not the end of it. Birds create nests in your vents, and given the vast amount of stuff they use to build said nest, it can end up completely clogging a vent, obstructing any airflow. As with rodents, a full duct cleaning from Service Experts Heating & Air Conditioning can remove any droppings, feathers, or other likely illness-carrying leave-behinds. You may also need an expert animal removal company to actually remove the birds from air vents or attics.

Mice in Air Ducts

If there are mice in your ductwork, you should take steps quickly to remove them. Mice nibble on wires and leave droppings like all rodents, but they also add to their population quickly. And when they run around in the ducts, treating it like the beltway of your house, they may die in there. This creates an unsanitary situation, and you may notice an unsavory odor.

You may suspect mice because of the sounds you hear – some scratching and scrabbling inside metal. Or you might actually spot one making an escape through the air vents in your house. You may even confirm their passage by inspecting the ducts for mice droppings. Either way, if you suspect mice you have a couple options. You may trap them yourself, by setting traps just inside each vent and checking them each morning. Or you could hire a professional exterminator.

If you’ve determined that the mice are exterminated, you should have your air ducts thoroughly cleaned by an HVAC company. If mice have been living in the walls, they will have left droppings in your ducts. Mice leavings are toxic, and if you leave them in your ducts they can make you and your family sick. Service Experts Heating & Air Conditioning offers duct cleaning services that will eliminate most debris from your home’s ventilation system.
