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

You don’t want to think about it, but often times dust isn’t all that is in your duct system. You might hear animal noises coming from air ducts and realize you have unwanted guests. You can attempt to lure the creatures out but they may be nesting and refuse to leave their babies. Call McElroy Service Experts for a complete duct cleaning and we will make sure your duct system is clear of all these nasty house guests, for instance:

Bugs and Insects

Not much is worse than trying to kill a spider and watching it run into your air vent. It’s impossible to get it now and all you can do is lay in your room and imagine the thing laying all those spider eggs. You may even think you hear some scuttling around your duct system. Fear not. McElroy Service Experts will come see you and give you a complete duct cleaning and ensure that spider and any of her bug friends are evicted. Babies, too.


When rodents make their way into your duct system, commonly through gaps in the duct work and fractures in the foundation or home exterior, it causes multiple issues. First, furry critters can leave droppings behind and can destroy anything they encounter, including Christmas 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 grass and leaves they’re likely carrying in to build a nest, and now there’s quite the fire hazard in your attic, duct system, and behind your walls. A good duct cleaning can remove rodent droppings or nests, but you might also need to call an expert wildlife removal company to remove the mice, squirrels, or other wildlife and maybe an electrician if there has been any damage to wiring.


Birds typically find safe and warm places to nestand your air vents meet that criteria. Nests mean babies, which means they are feeding 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 worst part. Birds assemble nests in your vents, and given the large amount of materials they use to assemble said nest, it can end up fully clogging a vent, obstructing any airflow. As with rodents, a thorough duct cleaning from McElroy Service Experts can get rid of any droppings, feathers, or other likely illness-carrying leave-behinds. You could also need animal control to actually remove the birds from air vents or attics.

Mice in Air Ducts

If you have mice in the ductwork, you should take steps quickly to remove them. Mice nibble on wiring and leave droppings like most rodents, but they also multiply quickly. And when they run around in the ducts, treating it like the highway of your home, they may pass away inside. This creates an unsanitary situation, and you may notice it due to the smell.

You may guess mice due to the noises you hear – lots of scratching and scrabbling along walls. Or you could actually spot one making an escape through the air vents in your walls. You might even confirm their passage by inspecting the ducts for mice leavings. If you suspect mice you have some choices. You could trap them yourself, by placing traps just inside each duct and checking them in the morning. Or you can contract a professional exterminator.

Once you have verified that the mice are removed, you should have your ducts professionally cleaned by an HVAC company. If mice have been there, they will have left droppings in your ducts. Mice droppings are toxic, and if you don’t remove them from your ducts they can make you and your family sick.
