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

It’s not fun to think about, but often times dust isn’t the only thing 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 Stevenson Service Experts for a complete duct cleaning and we will ensure your duct system is clear of all these unwelcome house guests, for instance:

Bugs and Insects

Nothing is worse than aiming to kill a spider and watching is escape into an air vent. It’s out of reach now and all you can do is lie in bed and imagine the thing laying all those baby spiders. You may even believe you hear a couple scuttling around your duct system. No worries. Stevenson Service Experts will come to your home and give you a complete duct cleaning and ensure that spider and any of her bug friends are good and gone. Babies, too.


When rats, squirrels, and other wildlife make a home in your duct system, generally through gaps in the duct work and breaks in the foundation or home exterior, it causes many issues. First, rodents can leave droppings behind and can ruin anything they come across, including holiday decorations or baby toys you’re storing in your attic. Second, those little guys tend to chew, which can leave you with exposed wiring. That joined with the dried leaves and twigs they’re likely bringing in to build a nest, and now you have quite the fire hazard in your attic, behind your walls, and in your duct system. A professional duct cleaning can eliminate rodent droppings or nests, but you may also need to call an expert wildlife removal company to remove the furry visitors and perhaps an electrician if there was any damage to the wiring.


Birds normally look for safe and warm places to nest, like your air vents. Nests mean baby birds, which means they are bringing food to babies, and that means BUGS. If you discover birds in your vents, you’ll likely end up with bugs in your home. But that’s not the end of it. Birds assemble nests in your vents, and given the large amount of stuff they use to build said nest, it can result in fully clogging a vent, obstructing any airflow. As with rodents, a thorough duct cleaning from Stevenson Service Experts can remove any droppings, feathers, or other potential illness-carrying leave-behinds. You might also need a professional wildlife 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 to remove them. Mice chew through electrical wires and leave droppings like most rodents, but they also multiply quickly. And when they run around in the ducts, treating it like the beltway of your residence, they eventually die in there. This creates an unsanitary situation, and you may notice it due to the smell.

You probably guess mice because of the noises you hear – plenty of scratching and scrabbling inside walls. Or you could actually spot one making an escape into the air vents in your home. You might even confirm their passage by inspecting the ducts for mice feces. If you you’re worried you have mice you have two options. You could trap them yourself, by setting traps inside each duct and checking them every morning. Or you might decide to contract a specialist.

Once you have verified that the mice are removed, you will need to have your air ducts thoroughly cleaned by an HVAC company. If mice have been living in the walls, they will have left feces in your ducts. Mice feces are toxic, and if you don’t remove them from your ducts they can make your household sick. Stevenson Service Experts offers duct cleaning services that will clean out most debris from your home’s airways.
