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

It’s not fun to think about, but sometimes dust isn’t exclusively what is in your duct system. You might have heard animal noises coming from air ducts and fear you have freeloading tenants. You can pull out all the stops to lure the critters out but they may be nesting and refuse to leave their babies. Call Bryant Heating & Cooling Service Experts for a thorough duct cleaning and we will make sure your duct system is rid of all these uninvited house guests, such as:

Insects and Bugs

There are few things worse than trying to kill a spider and watching it run into the air vent. It’s out of reach now and all you can do is lie in bed and imagine the spider laying all those spider eggs. You may even think you hear a couple scuttling around your duct system. Never fear. Bryant Heating & Cooling Service Experts will come out and give you a complete duct cleaning and assure that spider and any of her creepy-crawly friends are out of there. Babies, too.


When raccoons, mice, and other furry visitors find themselves in your duct system, commonly through holes in the duct work and cracks in the foundation or home exterior, it causes several issues. First, rodents can leave droppings behind and can destroy anything they get into, including holiday 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 twigs and dried grass they’re likely bringing in to manufacture a nest, and that creates quite the fire risk in your attic, behind your walls, and in your duct system. A full duct cleaning can remove rodent droppings or nests, but you may also need to call an expert wildlife removal company to remove the rodents and perhaps an electrician if there was any damage to the wiring.


Birds typically find safe and dry places to nest, like your air vents. Nests mean babies, which means they are finding food for 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 all. Birds create nests in your vents, and given the great amount of materials they use to assemble said nest, it can end up totally clogging a vent, obstructing any airflow. As with mice, squirrels, etc., a thorough duct cleaning from Bryant Heating & Cooling Service Experts can get rid of any droppings, feathers, or other possible 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 you’ve got mice in your ducts, you should take steps to remove them. Mice gnaw wires and leave refuse like most rodents, but they also add to their population quickly. And when they run around in the ducts, treating it like the highway of your residence, they usually die in the ducts. This creates a health hazard, and you may notice an unsavory odor.

You probably think of mice from the noises you hear – lots of scratching and scrabbling along ducts. Or you could actually see one making an escape through the heating vents in your house. You might even confirm their presence by inspecting the ducts for mice droppings. If you think there’s mice you have two choices. You could trap them yourself, by setting traps just inside each vent and checking them each morning. Or you might decide to hire a specialist.

If you have determined that the mice are gone, you really should have your ducts professionally cleaned by an HVAC company. If mice have been present, they will have left droppings in your ducts. Mice feces are toxic, and if you ignore them in your ducts they can make your household sick. Bryant Heating & Cooling Service Experts offers duct cleaning services that will clean out most debris from your home’s airways.
