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

It’s not fun to think about, but occasionally dust isn’t the only thing that is in your duct system. You might hear animal noises coming from air ducts and notice you have unwelcome visitors. You can pull out all the stops to lure the little guys out but they may not leave their babies if they are nesting. Call San Antonio Air Service Experts for a thorough duct cleaning and we will make sure your duct system is rid of all these nasty house guests, for instance:

Bugs and Insects

There are few things worse than trying to kill a spider and seeing it run into the air vent. It’s impossible to get 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 a couple racing around your duct system. Fear not. San Antonio Air Service Experts will come to your home and give you a complete duct cleaning and ensure that spider and any of her creepy-crawly friends are good and gone. The offspring, too.


When raccoons, mice, and other furry visitors find themselves in your duct system, normally through openings in the duct work and breaks in the foundation or home exterior, it causes several issues. First, furry critters can leave droppings behind and can ruin anything they come across, including Christmas decorations or old toys you’re saving in your attic. Second, animals tend to chew, which can cause exposed wiring. That mixed with the twigs and dried grass they’re likely taking in to manufacture a nest, and now there’s quite the fire hazard in your attic, duct system, and behind your walls. A thorough duct cleaning can remove rodent droppings or nests, but you could also need to call a professional animal removal company to remove the rodents and perhaps an electrician if there was any wire damage.


Birds normally look for 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 likely 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 assemble said nest, it can end up completely clogging a vent, stopping any airflow. As with our furry friends, a full duct cleaning from San Antonio Air 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 your vents or attics.

Mice in Air Ducts

If you have mice in your home’s ducts, you should take steps quickly to remove them. Mice gnaw wires and leave refuse like all rodents, but they also multiply quickly. And when they run around in the ducts, treating it like the road system of your residence, they usually die in there. This creates unhealthy living conditions, and you may notice unpleasant scents.

You probably guess mice because of the noise you hear – lots of scratching and scrabbling along air ducts. Or you could actually see one making an escape through the air vents in your home. You might even confirm their status by inspecting the ducts for mice feces. Either way, if you think there’s mice you have a couple choices. You could trap them yourself, by placing traps on the interior of each duct and checking them each morning. Or you could pay for a specialist.

If 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 living in the walls, they will have left feces in your ducts. Mice leavings are toxic, and if you ignore them in your ducts they can make you sick. San Antonio Air Service Experts offers duct cleaning services that will eliminate most debris from your home’s air ducts.
