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

It’s not fun to think about, but occasionally dust isn’t the only thing that is in your duct system. You might hear animal noises coming from air ducts and realize you have unwanted visitors. You can attempt to 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 confirm your duct system is rid of all these nasty house guests, such as:

Bugs and Insects

Nothing is worse than aiming to kill a spider and watching is escape into your air vent. It’s out of reach now and all you can do is lay in your room and imagine the thing laying all those baby spiders. You may even think you hear a couple scuttling around your duct system. Never fear. Service Experts Heating & Air Conditioning will come see you and give you a full duct cleaning and make sure that spider and any of her creepy-crawly friends are out of there. The offspring, too.


When rodents make their way into your duct system, normally through openings in the duct work and breaks in the foundation or home exterior, it causes multiple issues. First, wildlife can leave droppings behind and can tear up anything they get into, including holiday decorations or old baby clothes you’re keeping in your attic. Second, animals tend to chew, which can cause exposed wiring. That joined with the dried grass and leaves they’re likely bringing in to create a nest, and now you have quite the fire risk in your duct system, your attic, or behind your walls. A good duct cleaning can eliminate rodent droppings or nests, but you may also need to call animal control to remove the rodents and possibly an electrician if there was any damage to the wiring.


Birds typically find safe and sheltered places to nestand your air vents are perfect. Nests mean eggs, which means they are feeding babies, and that means BUGS. If you have birds in your vents, you’ll presumably end up with six-legged and eight-legged critters in your home. But that’s not all. Birds build nests in your vents, and given the great amount of materials they use to assemble said nest, it can result in fully clogging a vent, stopping any airflow. As with rodents, a completely duct cleaning from Service Experts Heating & Air Conditioning can get rid of any droppings, feathers, or other possible illness-carrying leave-behinds. You could also need an expert animal removal company to actually remove the birds from your vents or attics.

Mice in Air Ducts

If you’ve got mice in the ductwork, you should take steps quickly to remove them. Mice gnaw wiring and leave droppings like most rodents, but they also grow their population quickly. And when they run around in the ducts, treating it like the road system of your residence, they may die in there. This creates a health hazard, and you may notice unpleasant scents.

You probably suspect mice because of the noises you hear – lots of scratching and scrabbling inside ductwork. Or you may actually see one making an escape into the air vents in your house. You could even confirm their presence by inspecting the ducts for mice leavings. If you you’re worried you have mice you have two choices. You may trap them yourself, by setting traps just inside each vent and checking them every morning. Or you could hire a specialist.

If you’ve verified that the mice are removed, you really should have your ductwork thoroughly cleaned by an HVAC company. If mice have been living in the walls, they will have left feces 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 remove most debris from your home’s airways.
