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

It’s not fun to think about, but occasionally dust isn’t all that is in your duct system. You may hear animal noises coming from air ducts and notice you have unwanted tenants. You can try and lure the little guys 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 make sure your duct system is free of all these unwelcome house guests, including:

Bugs and Insects

Not much is worse than trying to kill a spider and seeing it escape into an air vent. It’s out of reach now and all you can do is sit on the couch and imagine the spider laying all those spider eggs. You may even think you hear some scurrying around your duct system. Don’t worry. Service Experts Heating & Air Conditioning will come to your home and give you a thorough duct cleaning and ensure that spider and any of her creepy-crawly friends are evicted. Eggs, too.


When rodents make their way into your duct system, commonly through holes in the duct work and cracks in the foundation or home exterior, it causes multiple issues. First, wildlife can leave droppings behind and can ruin anything they come across, including Christmas decorations or old baby clothes you’re keeping in your attic. Second, those little guys tend to chew, which can result in exposed wiring. That joined with the dried grass and leaves they’re likely taking in to manufacture a nest, and now you have quite the fire danger in your attic, behind your walls, and in your duct system. A professional duct cleaning can get rid of rodent droppings or nests, but you could also need to call animal control to remove the furry visitors and possibly an electrician if there was any wire damage.


Birds normally get into safe and dry places to nestand your air vents are perfect. Nests mean babies, which means they are feeding babies, and that means BUGS. If you discover birds in your vents, you’ll presumably end up with creepy-crawlies in your home. But that’s not all. Birds build nests in your vents, and given the vast amount of leaves and grass they use to assemble said nest, it can result in completely clogging a vent, preventing any airflow. As with rodents, a full duct cleaning from Service Experts Heating & Air Conditioning can get rid of any droppings, feathers, or other potential illness-carrying leave-behinds. You could also need animal control to actually remove the birds from your vents or attics.

Mice in Air Ducts

If there are mice in your home’s ducts, you should take steps quickly to remove them. Mice chew through wires and leave feces like all rodents, but they also multiply quickly. And when they run around in the ducts, treating it like the road system of your home, they eventually die in the ducts. This creates unhealthy living conditions, and you may notice an unsavory odor.

You may suspect mice from the noise you hear – lots of scratching and scrabbling inside air ducts. Or you could actually see one making an escape into the air vents in your home. You may even confirm their presence by inspecting the ducts for mice droppings. Either way, if you suspect mice you have a couple options. You may trap them yourself, by placing traps just inside each vent and checking them every morning. Or you can contract a pest control company.

Once you’ve verified that the mice are removed, you really should have your ductwork professionally cleaned by an HVAC company. If mice have been there, they will have left droppings in your ducts. Mice droppings are toxic, and if you ignore 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 air ducts.
