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

It’s unpleasant to consider, but occasionally dust isn’t all that is in your duct system. You might hear animal noises coming from air ducts and fear you have unwanted guests. You can pull out all the stops to lure the creatures out but they may not leave their babies if they are nesting. Call All American Air Service Experts for a comprehensive duct cleaning and we will make sure your duct system is free of all these unwanted house guests, such as:

Insects and Bugs

There are few things worse than working to kill a spider and watching is escape into your air vent. You can’t get to it now and all you can do is lay in bed and imagine it laying all those spider babies. You may even think you hear some scampering around your duct system. No worries. All American Air Service Experts will come out and give you a full duct cleaning and make sure that spider and any of her creepy-crawly friends are good and gone. Eggs, too.


When rodents make their way into your duct system, commonly through gaps in the duct work and breaks in the foundation or home exterior, it causes several issues. First, wildlife can leave droppings behind and can tear up anything they get into, including Christmas decorations or baby toys you’re storing in your attic. Second, rodents tend to chew, which can cause exposed wiring. That joined with the twigs and dried grass they’re likely carrying in to manufacture a nest, and now you have quite the fire hazard in your attic, behind your walls, and in your duct system. A good duct cleaning can get rid of rodent droppings or nests, but you may also need to call animal control to remove the rodents and perhaps an electrician if there was any wire damage.


Birds typically look for safe and dry places to nestand your air vents are perfect. Nests mean baby birds, which means they are finding food for babies, and that means BUGS. If you have birds in your vents, you’ll probably end up with creepy-crawlies in your home. But that’s not all. Birds create nests in your vents, and given the vast amount of leaves and grass they use to create said nest, it can wind up completely clogging a vent, stopping any airflow. As with our furry friends, a thorough duct cleaning from All American Air Service Experts can eliminate any droppings, feathers, or other possible illness-carrying leave-behinds. You might also need an expert animal removal company to actually remove the birds from the vents or attics.

Mice in Air Ducts

If you’ve got mice in your air ducts, you should take steps to quickly remove them. Mice chew through wires and leave droppings like most rodents, but they also add to their population quickly. And when they run around in the ducts, treating it like the road system of your residence, they eventually pass away inside. This creates an unsanitary situation, and you may notice an unsavory odor.

You might guess mice due to the sounds you hear – plenty of scratching and scrabbling in ductwork. Or you might actually notice one making an escape into the vents in your walls. You could even confirm their status by inspecting the ducts for mice leavings. If you suspect mice you have two options. You could trap them yourself, by placing traps inside each vent and checking them in the morning. Or you might decide to hire a professional exterminator.

Once you have verified that the mice are gone, you really should have your ducts thoroughly cleaned by an HVAC company. If mice have been living in the walls, they will have left mice refuse in your ducts. Mice droppings are toxic, and if you ignore them in your ducts they can make you sick. All American Air Service Experts offers duct cleaning services that will clean out most debris from your home’s airways.
