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 may hear animal noises coming from air ducts and notice you have unwanted visitors. You can try and lure the creatures out but they may not leave their babies if they are nesting. Call Service Experts Heating & Air Conditioning for a comprehensive duct cleaning and we will assure your duct system is rid of all these unwelcome house guests, for instance:

Insects and Bugs

Nothing is worse than working to kill a spider and watching is escape into an 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 babies. You may even believe you hear a few racing around your duct system. No worries. Service Experts Heating & Air Conditioning will come out and give you a full duct cleaning and assure that spider and any of her creepy-crawly friends are out of there. Eggs, too.


When rodents make their way into your duct system, commonly through holes in the duct work and breaks in the foundation or home exterior, it causes many issues. First, furry critters can leave droppings behind and can ruin anything they encounter, including holiday decorations or baby toys you’re storing in your attic. Second, those little guys tend to chew, which can result in exposed wiring. That combined with the dried leaves and twigs they’re likely carrying in to create a nest, and now you have quite the fire danger in your attic, duct system, and behind your walls. A professional duct cleaning can eliminate rodent droppings or nests, but you may also need to call a professional animal removal company to remove the rodents and maybe an electrician if there was any wire damage.


Birds typically get into safe and warm places to nest, like your air vents. Nests mean babies, 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 creepy-crawlies in your home. But that’s not the end of it. Birds construct nests in your vents, and given the great amount of leaves and grass they use to build said nest, it can wind up fully clogging a vent, preventing any airflow. As with mice, squirrels, etc., a thorough duct cleaning from Service Experts Heating & Air Conditioning can eliminate any droppings, feathers, or other possible illness-carrying leave-behinds. You may also need an expert animal removal company to actually remove the birds from your vents or attics.

Mice in Air Ducts

If there are mice in the ducts, you should take steps to quickly remove them. Mice chew through wires and leave feces like all rodents, but they also grow their population quickly. And when they run around in the ducts, treating it like the highway of your house, they usually die in there. This creates unhealthy living conditions, and you may notice unpleasant scents.

You may guess mice due to the sounds you hear – lots of scratching and scrabbling in air ducts. Or you may actually see one making an escape into the air vents in your home. You could even confirm their status by inspecting the ducts for mice feces. Either way, if you suspect mice you have two choices. You may trap them yourself, by setting traps on the interior of each duct and checking them in the morning. Or you can hire a pest control company.

If you’ve determined that the mice are gone, you should have your air ducts thoroughly cleaned by an HVAC company. If mice have been living in the walls, they will have left droppings in your ducts. Mice droppings are toxic, and if you leave them in your ducts they can make your household sick. Service Experts Heating & Air Conditioning offers duct cleaning services that will clean out most debris from your home’s ventilation system.
