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 hear animal noises coming from air ducts and realize you have unwanted tenants. You can attempt to lure the creatures out but they may not leave their babies if they are nesting. Call Service Experts Commercial HVAC for a comprehensive duct cleaning and we will make sure your duct system is clear of all these nasty house guests, such as:

Insects and Bugs

Not much is worse than working to kill a spider and watching it run into your air vent. It’s out of reach now and all you can do is lay in bed and imagine the thing laying all those spider eggs. You may even believe you hear some scampering around your duct system. No worries. Service Experts Commercial HVAC will come to your home and give you a full duct cleaning and ensure that spider and any of her creepy-crawly friends are good and gone. Eggs, too.


When rats, squirrels, and other wildlife make a home in your duct system, usually through holes in the duct work and fractures in the foundation or home exterior, it causes multiple issues. First, rodents can leave droppings behind and can tear up anything they encounter, including seasonal decorations or old baby clothes you’re keeping in your attic. Second, rodents tend to chew, which can cause exposed wiring. That mixed with the dried leaves and twigs they’re likely bringing in to create a nest, and that creates quite the fire hazard in your attic, duct system, and behind your walls. A complete duct cleaning can remove rodent droppings or nests, but you could also need to call animal control to remove the mice, squirrels, or other wildlife and maybe 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 eggs, which means they are bringing food to babies, and that means BUGS. If you have birds in your vents, you’ll probably end up with bugs in your home. But that’s not the worst part. Birds assemble nests in your vents, and given the large amount of leaves and grass they use to build said nest, it can result in completely clogging a vent, obstructing any airflow. As with rodents, a professional duct cleaning from Service Experts Commercial HVAC can eliminate 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 the vents or attics.

Mice in Air Ducts

If there are mice in your ductwork, you should take steps to quickly remove them. Mice chew through wiring and leave feces like most rodents, but they also add to their population quickly. And when they run around in the ducts, treating it like the beltway of your home, they eventually pass away inside. This creates unhealthy living conditions, and you may notice an unsavory odor.

You probably think of mice from the noises you hear – some scratching and scrabbling inside metal. Or you may actually spot one making an escape through the vents in your walls. You might even confirm their presence by inspecting the ducts for mice feces. Either way, if you you’re worried you have mice you have some choices. You can trap them yourself, by setting traps just inside each vent and checking them each morning. Or you can hire a specialist.

Once you have determined that the mice are removed, you will need to have your ductwork expertly cleaned by an HVAC company. If mice have been there, they will have left feces in your ducts. Mice leavings are toxic, and if you leave them in your ducts they can make your household sick.
